cisco switch domain name command

-Dynamic NAT may use a pool of outside addresses. Any performance issues with your switch can have a substantial impact on your users. Learning. This table illustrates how different banner command options work with various types of connections. Important "Show Commands" for Cisco Switches Command: show mac address-table. If the autoreconfigure option is disabled on either or both switches, the links between the two switches become isolated. How to Enable SSH on Cisco Switch, Router and ASA - The Geek Stuff vsan 3. Authentication can be with a local username and password or with an authentication, authorization, and accounting (AAA) server that runs TACACS+ or RADIUS. For example c3750e-universalk9-tar.122-35.SE5.tar is a k9 (crypto) image. When the persistent FC ID feature is enabled, you can enter the persistent FC ID submode and add static or dynamic entries in the FC ID database. Enabling Domain Name Services - Cisco IOS Cookbook, 2nd Edition [Book] You can do this by entering the following command: The new IP management address is located in VLAN1, which other computers will now use to connect. If you do not configure a domain ID, the local switch sends a random ID in its request. By default, the configured domain ID is 0 (zero) and the configured type is preferred. 07:24 AM, Taken fully fromhttp://nusdsmhs.ss4.sharpschool.com/UserFiles/Servers/Server_41705/Image/CCNA%20IOS%20Commands%20Summary%2010-1-14.pdf, show ip interface brief (display interface designations, IP address and status), show vlan brief (on switch - show what VLANs exist, names, ports assigned ), show controllers serial x/x/x (see if DCE or DTE connected and if clockrate is present), show interface trunk (what ports are trunking, native vlan, allowed vlans), show running-config (display the running configuration - active), show startup-config (display the startup configuration), show ip protocol (what routing protocol, which networks, passive interfaces, neighbors), show cdp neighbors (see directly connected Cisco devices), show cdp neighbors detail (includes IP address at other end), show cdp interface (which interfaces are running CDP), show interface serial x/x/x (what encapsulation, IP address, counters), show interface fastethernet x/x switchport (configured mode and operating mode), show version (which IOS, capability, memory, configuration-register), show run | begin interface (will start listing at the first instance of interface), show ip route connected (show routing table entries for directly connected networks), show ip route static (show routing table entries for static routes), show ip route ospf (show routing table entries learned through OSPF), show ip route eigrp (show routing table entries learned through EIGRP), show mac-address-table or show mac address-table (varies with different IOS), show flash (display filenames and directories in Flash memory), show clock (current date/time in this device), show ipv6 ??? To solve this problem you can select a virtual LAN(VLAN) on the switch and create a virtual interface with an IP address. Create the encryption keys using the crypto key generate rsa global configuration command. By default, the contiguous domain assignment is disabled. The local switch sends a configured domain ID request to the principal switch. Reverts to the factory default of allowing domain IDs from 1 through 239 in VSAN 5. The valid range to set the priority is between 1 and 254. Forces the VSAN to reconfigure with data traffic disruption. Below is an example: R-1(config)# ip access-list extended NAME (name the list). To commit pending domain configuration changes and release the lock, follow these steps: Commits the pending domain configuration changes. Delete the RSA key pairs. While the static option can be applied at runtime after a disruptive or non-disruptive restart, the preferred option is applied at runtime only after a disruptive restart (see the "About Domain Restart" section). **Multi-Point with sub-interface; Sample Configuration 4: R1(config-if)# encapsulation frame-relay (not configured on sub-interface), R1(config-if)# interface serial 0/0/0.752 multipoint (sub-interface # is customarily DLCI #), R1(config-subif)# ip address 192.168.5.1 255.255.255.248 (not /30), R1(config-subif)# frame-relay map ip 192.168.5.1 752 (to allow local ping- 192.168.5.1 is the local interface IP, DLCI=752 is a valid DLCI for this interface), R1(config-subif)# frame-relay map ip 192.168.5.2 752 broadcast [ietf, cisco] (192.168.5.2 is next hop, DLCI=752, broadcast is optional, PVC=IEFT is optional cisco is default), R1(config-subif)# frame-relay map ip 192.168.5.3 339 broadcast [ietf, cisco] (192.168.5.3 is next hop, DLCI=339, broadcast is optional, PVC=IEFT is optional cisco is default), R1# show frame-relay map (display mapping of IPs and DLCIs). Following basic commands are used to configure a new switch : 1. 8. A configuration mode command to establish a static translation between an inside local address and an inside global address, Creates a VLAN and enters VLAN configuration mode for further definitions. 2. To add a banner message : It provides a short message to the user who wants to access the switch. First test the authentication without SSH to make sure that authentication works with the router Carter before you add SSH. To enable the domain manager fast restart feature in Cisco SAN-OS Release 3.0 (2) or later, follow these steps: About Switch Priority By default, the configured priority is 128. Each command can add multiple servers. To reject incoming RCF request frames, follow these steps: switch(config-if)# fcdomain rcf-reject vsan 1. 4. All rights reserved. You will be unable to complete the crypto key generate rsa command without a host name and IP domain name. The first action that modifies the existing configuration creates the pending configuration and locks the feature in the fabric. This configuration is applicable to both disruptive and nondisruptive restarts. I have different field in IT and willing to learn Networking. You can use netmask: R-1(config)# ip nat pool POOL-NAME 73.2.34.138 73.2.34.143 netmask 255.255.255.248. Using a network monitoring tool and network analyzer can help you to monitor switches remotely and review performance concerns. You can enable the distribution of the allowed domain ID list s configuration information to all Cisco MDS switches in the fabric using the Cisco Fabric Services (CFS) infrastructure. Specify the SSH key type and version. A disruptive restart is required to apply most configuration changes-including manually assigned domain IDs. Example17-2 shows the following: A switch with WWN of 20:01:00:05:30:00:47:df is the principal switch and has domain 200. Learn more about how Cisco is using Inclusive Language. Go to the, When the options controlling local serial lines page displays enter the COM port your network is connected to in the, Next, enter the digital transmission speed of your switch model. # config t (config)# hostname myswitch (config)# ip domain-name thegeekstuff.com 3. Changes the fabric name value to the factory default (20:01:00:05:30:00:28:df) in VSAN 3010. For example, when the Secure Shell ssh client is used, the login banner is displayed. preferred vsan 8. The IP addresses are inside / outside: R-1(config)# ip nat inside source static 192.168.10.22 73.2.34.137. 03-06-2020 Enter the range of ports you want to close by entering the following command (you would change 0/25-48 to the ports that you want to close): Once youve finished configuring the router its time to save your system configuration. Press "Enter". Lists information about the currently operational trunks and the VLANs supported by those trunks, Lists each VLAN and all interfaces assigned to that VLAN but does not include trunks, Lists the current VTP status, including the current mode, Sets a static route in the IP routing table, Enables a Routing Information Protocol (RIP) routing process, which places you in router configuration mode, In router configuration mode, associates a network with a RIP routing process, In router configuration mode, configures the software to receive and send only RIP version 2 packets, In router configuration mode, disables automatic summarization, In router configuration mode, generates a default route into RIP. Only needed if there are static routes), (turn off automatic classful summarization- suggested), (include this interface and subnet in routing), (completely remove this instance of EIGRP in this router), (100=Process ID within this network Cisco calls this Autonomous System), (use this ID when identifying EIGRP neighbors), (the default is to summarize to classful boundaries), (no subnet or wildcard mask is needed if classful), (one statement redistributes static routes - including the default-route), (load balancing paths: default=4, no load balancing=1), (indicate the serial line speed for the routing protocol this example is 768-K), (manually summarized network statement configured on outbound interface), (ex. Syntax Router (config)#ip name-server <name> Example In this example we configure the ip name-server command to allow a router to resolve hostnames. The valid range to set the priority is between 1 and 254. limit EIGRP AS=100 updates to a max of 40% of link bandwidth), (ex. Please use Cisco.com login. 2. Any new switch cannot become the principal switch when it joins a stable fabric. To start configuration, you want to connect the switch console to PuTTY. Configuring a Hostname and Domain Name - Cisco Certified Expert When we think of connectivity in a network, the router is probably the first device that comes to mind, but switches play a vital role in enabling network devices to communicate. Enables the automatic reconfiguration option in VSAN 10. switch(config)# no fcdomain auto-reconfigure 69. The banner then prompts for a password. Taking the time out of your day to configure a switch and assign strong passwords gives you peace of mind so that you can communicate safely online. If you have already configured SSH, it is recommended that you reconfigure the SSH server in the device. Each network requires at least one server to resolve addresses. set hello intervals on this interface to 30s for EIGRP AS=100), R1(config-if)# ip hold-time eigrp 100 90 (in this example, set the hold-time on this interface to 90s for EIGRP AS=100), R1(config)# key chain MYCHAIN (name the key chain done in global config), R1(config-keychain)# key 1 (must assign a number same at both ends of link), R1(config-keychain-key)# key-string securetraffic (securetraffic is the passphrase), R1(config)# interface serial 0/1 (interface to the other EIGRP router), R1(config-subif)# ip authentication mode eigrp 10 md5 (turn on authentication), R1(config-subif)# ip authentication key-chain eigrp 10 MYCHAIN (use this key), R1# show ip eigrp neighbors (see neighbor adjacencies), R1# show ip eigrp topology (see the EIGRP topology table), R1# debug eigrp fsm (see what DUAL does when a route is removed from the routing table), R1(config)# interface loopback 10 (optionally create a virtual interface for OSPF router ID), R1(config)# router ospf 1 (configure an OSPF routing process), R1(config-router)# router-id 2.2.2.2 (optionally configure the OSPF Router ID - Suggested), R1(config-router)# network 172.16.45.0 0.0.0.255 area 0 (include directly connected networks that match this parameter), R1(config-router)# default-information originate (propagate the quad-0 default route), R1(config-router)# redistribute static (propagate classful static routes configured on this router to other OSPF routers), R1(config-router)# redistribute static subnets (propagate classless static routes configured on this router to other OSPF routers), R1(config-router)# passive-interface fastethernet 0/1 (do not send OSPF routing updates out this interface), R1(config-router)# area 7 range 172.16.8.0 255.255.248.0 (on ABR summarize addresses), R1(config-router)# summary address 172.16.8.0 255.255.248.0 (On ASBR to summarize non-OSPF routes imported into OSPF), R1(config-router)# auto-cost reference-bandwidth ? Note In an IVR without NAT configuration, if one VSAN in the IVR topology is configured with static domain IDs, then the other VSANs (edge or transit) in the topology should also be configured with static domain IDs. Most people disable this command as it can be a frequent annoyance to those who mistype words on a regular basis. switch(config)# no fcdomain I see that this tutorial help me alot. Closing these ports down reduces the number of entry points into your network and makes your switch more secure. Consequently, the runtime fabric name is the same as the configured fabric name. After the RSA key pairs are deleted, the SSH server is automatically disabled. Use the show fcdomain command to display global information about fcdomain configurations. Partnership. The configured domain ID becomes 0 preferred. Non-disruptive domain restarts are acceptable only when changing a preferred domain ID into a static one (and the actual domain ID remains the same). Static entries and FC IDs currently in use cannot be deleted. Follow these steps for a workaround: These steps will create a static IP address, which you can check by going from the main menu to IP Configuration > IPv4 Interface. When you configure RSA key pairs, you can get these error messages: You must use the hostname global configuration command to configure a host name for the router. Sets the VLAN that the interface belongs to. FC ID allocationThis phase guarantees a unique FC ID assignment to each device attached to the corresponding switch in the fabric. CFS distribution of allowed domain ID lists is disabled by default. Enables domain manager fast restart on VSAN3. switch(config)# fcdomain optimize fast-restart Enables the fcdomain configuration in VSAN 2008. As a prerequisite for the next command, configure a DNS domain name with the ip domain-name name global configuration command. See Example17-8. enable and configure a Cisco router/switch for the SSH server, you must configure SSH parameters. To enable the persistent FC ID feature, follow these steps: switch(config)# fcdomain fcid persistent vsan 1000. This feature allows you to synchronize the configuration across the fabric from the console of a single MDS switch. Set hostname and domain-name Next, make sure the switch has a hostname and domain-name set properly. Use the show fcdomain statistics command to display frame and other fcdomain statistics for a specified VSAN or PortChannel. Before we begin, enter Global Configuration Mode by executing the following command: Completing simple tasks like configuring passwords and creating network access lists controls who can access the switch can enable you to stay secure online. Note: You can receive the SSH2 0: Unexpected mesg type received error message due to a packet received that is not understandable by the router. The locally configured domain ID of the switch must be in the allowed list. This screen shot shows that the login banner is displayed when PuTTY is configured to send the username to the router. Verify that the port field of the FC ID is 0 (zero) when configuring an area. Go to CLI tab in the popup window. Allowed domain ID list configuration distribution, Chapter6, "Using the CFS Infrastructure. Note Within a VSAN all switches should have the same domain ID type (either static or preferred). The access port is set to access unconditionally and operates as a non-trunking, single VLAN interface that sends and receives non-encapsulated (non-tagged) frames. The principal switch assigns domain IDs that are available in the locally configured allowed domain list. This screenshot shows that the PuTTY client connects to the router and prompts for the username and password. Disables the contiguous allocation option and reverts it to the factory default in VSAN 1030. Go to Cisco Switch Username Command website using the links below Step 2. To disable or reenable fcdomains in a single VSAN or a range of VSANs, follow these steps: Disables the fcdomain configuration in VSAN 7 through 200. Figure17-2 Configuration Process Using the preferred Option. If you want to have one device act as an SSH client to the other, you can add SSH to a second device called "Reed". A disruptive reconfiguration may affect data traffic. 11:22:11:22:33:44:33:44 fcid 0x070123 dynamic. If for any reason putty is not an option for your setup, you can get similar results with a PuTTY alternative. Disables (default) the RCF filter on the specified interface in VSAN 1. In this guide, were going to perform a Cisco switch configuration through the command-line interface (CLI) with the open-source SSH/Telnet client PuTTY (although you can use another tool if you prefer). In router configuration mode, sets only that interface to passive RIP mode. Syntax Router (config)#ip domain-name <name> Example In the below example, we set R1 to have a domain name of "cisco.com". Then use the crypto key generate rsa command to generate a RSA key pairs and enable the SSH server. Tip The pending changes are only available in the volatile directory and are discarded if the switch is restarted. You can display the differences between the pending configuration and the current configuration using the show fcdomain pending-diff command. See Examples 17-4 and 17-5. The following commands will select a range of interfaces (from 1 to 24) and add all of them to vlan20. Enter global configuration mode: configure terminal The following example shows the configuration mode prompt. When an N or NL port logs into a Cisco MDS 9000 Family switch, it is assigned an FC ID. The HBA port connects to interface fc1/9 and the storage port connects to interface fc 1/10 in the same switch. Prevent "Translating. domain server (255.255.255.255)" Messages - Cisco A persistent FC ID assigned to an F port can be moved across interfaces and can continue to maintain the same persistent FC ID. By default, the configured priority is 128. (optionally change ref bw - Mbits/s 1-4294967; must be same on all routers), R1(config-router)# area AREA-ID authentication message-digest (globally activate MD-5 authentication within an OSPF area), R1(config-router)# ip ospf message-digest-key 1 md5 PASSWORD (authentication key), R1(config-if)# ip ospf message-digest-key 1 md5 PASSWORD (on this interface, configure the OSPF auth key will not activate authentication), R1(config-if)# ip ospf authentication message-digest (activate OSPF authentication), R1(config-if)# ip ospf cost 1562 (optionally configure an absolute OSPF cost for a link this example same as bandwidth 64), R1(config-if)# ip ospf hello-interval seconds (change hello timer from default 10 seconds), R1(config-if)# ip ospf dead-interval seconds (change dead timer from default 40 seconds), R1(config-if)# ip ospf priority {0 - 255} (for OSPF DR/BDR election, default=1, ineligible=0), R1# show ip ospf neighbor (display OSPF neighbor adjacencies State should be FULL or 2WAY), R1# show ip protocols (includes the OSPF Router ID of this router), R1# clear ip ospf process (re-calculate OSPF Router ID based on current parameters), R1# show ip ospf (display OSPF process and router IDs, as well as area information), R1# show ip ospf interface serial 0/0/0 (see DR/BDR information, hello and dead intervals), R1(config)# ipv6 unicast-routing (turn on ipv6 routing), R1(config)# no ipv6 router ospf 55 (remove this instance of OSPF in this router), R1(config)# ipv6 router ospf 100 (create the OSPF process in this router), R1(config-rtr)# router-id 5.5.5.5 (must have router id), R1(config-rtr)# default-information originate (redistribute default route to other routers), R1(config-rtr)# redistribute static (redistribute classful static routes, including default), R1(config-rtr)# redistribute static subnets (redistribute classless static routes), R1(config-rtr)# passive-interface default (no routing updates out any interface), R1(config-rtr)# no passive-interface gi 1/0 (allow updates out this interface), R1(config-rtr)# passive-interface gi 1/1 (no routing updates out gi 1/1), R1(config)# interface gi 1/1 (networks are assigned through the interface), R1(config-if)# ipv6 enable (allow IPv6 on this interface), R1(config-if)# ipv6 ospf 100 area 0 (associate this interface with IPv6 OSPF 55, area 0), R1(config)# no ipv6 router eigrp 100 (remove this instance of EIGRP in this router), R1(config)# ipv6 router eigrp 100 (create the EIGRP process), R1(config-rtr)# eigrp router-id 5.5.5.5 (must have a router id), R1(config-rtr)# redistribute static (redistribute static and default routes to other routers), R1(config-rtr)# no shutdown (must turn on EIGRP in this router), R1(config-if)# ipv6 eigrp 100 (associate this interface with IPv6 EIGRP process 100), R1(config-if)# ipv6 summary-address eigrp 100 2001:123A:AAA0::/60 (EIGRP summary address), R1(config-if)# ipv6 bandwidth-percent eigrp 100 40 (in this example limit EIGRP AS=100 updates to a maximum of 40% of the link bandwidth), R1(config-subif)# ipv6 authentication mode eigrp 10 md5 (turn on authentication), R1(config-subif)# ipv6 authentication key-chain eigrp 10 MYCHAIN (use this key), R1(config)# username R-2 password PASSWORD (configure for PAP / CHAP), R1(config)# interface serial 0/0/0 (select the interface for ppp configuration), R1(config-if)# encapsulation ppp (set interface to PPP), R1(config-if)# compress [predictor / stac] (optional-configure data compression), R1(config-if)# ppp quality [percentage] (optional-set a threshold of throughput before the ppp link will reset), R1(config-if)# ppp authentication pap (optional-configure for PAP authentication), R1(config-if)# ppp pap sent-username R-1 password PASSWORD (if PAP is used, this must be configured), R1(config-if)# ppp authentication chap (optional-configure for CHAP authentication), R1(config-if)# ppp multilink (optional-combine multiple PPP links for more bandwidth), R1(config-if)# encapsulation hdlc (reset the interface to the default value of HDLC). A change in the domain name or host name can trigger this error message. Enter the IP address of the server your network analyzer is on (Change the IP address): Switch# destination 117.156.45.241. A configuration mode command to establish dynamic source translation. Use the show fcdomain address-allocation command to display FC ID allocation statistics including a list of assigned and free FC IDs. At this point, the show crypto key mypubkey rsa command must show the generated key. The procedure in this example uses a switch domain of 111(6f hex). Code examples. If you have full communication between your VTP network, you only need to use this command on the VTP server because other switches will automatically learn the VTP domain from received updates. The IVR manager obtained virtual domain 97 using 20:01:00:05:30:00:47:df as the WWN for a virtual switch. So if you type ping "server.net.com" on your router and the router has been configured with a DNS server to use it can resolve "server.net.com" to an IP address. 3. All Show Commands in Cisco Switch and Router - Snabay Networking Enable SSH transport support for the vty. no ip-domain lookup command - Cisco To configure a domain name string for the client, use the following command in DHCP pool configuration mode: Command Purpose. 33:e8:00:05:30:00:16:df fcid 0x070128. Renaming a Cisco IP switch - NetApp LoginAsk is here to help you access Cisco Switch Username quickly and handle each specific case you encounter. The banner command output varies between the Telnet and different versions of SSH connections. The Cisco IOS image used must be a k9(crypto) image in order to support SSH. When you join two switches belonging to two different stable fabrics that have overlapping domains, the following cases apply: If the autoreconfigure option is enabled on both switches, a disruptive reconfiguration phase is started. Step2 Shut down the HBA interface in the MDS switch. A configuration mode command that denes the password required when using the, A configuration mode command that sets this Cisco device password that is required for any user to enter enable mode, A configuration mode command that directs the Cisco IOS software to encrypt the passwords, CHAP secrets, and similar data saved in its configuration file, A configuration mode command that creates and stores (in a hidden location in ash memory) the keys that are required by SSH. IQCode. Learn how your comment data is processed. Configures the switch in VSAN 8 to request a preferred domain ID 3 and accepts any value assigned by the principal switch. There can be additional optional commands (log, time-of-day, established, etc) on the end of most statements. Used in vty line conguration mode, denes whether Telnet or SSH access is allowed into this switch. You can display the status of the distribution session using the show fcdomain session-status vsan command. When it initiates the SSH session with the Cisco router, the login banner is displayed if the SSH client sends the username. ): Next, enter Global Configuration Mode and enter the following command: You can make the switch easier to locate in the network by assigning a hostname. Ensure that the required VSAN is an active VSANpersistent FC IDs can only be configured on active VSANs. The autoreconfigure option takes immediate effect at runtime. Thanks. To enable contiguous domains in a specific VSAN (or a range of VSANs), follow these steps: switch(config)# fcdomain contiguous-allocation Configure Telnet and Console Access Passwords, 5. The domains are configured on a per VSAN basis. If you discard (abort) the pending changes, the configuration remains unaffected and the lock is released. (does the IPv6 version of many IPv4 commands), show processes (shows active processes running on router), show users (show who is telnetted into this device), ping X.X.X.X (try to reach the destination host at X.X.X.X), trace X.X.X.X (show the path taken to reach the destination host at X.X.X.X), R1(config)# do show ??? Don't miss. (This step is optional.). Ensure you have specified a host name and domain. In this case, the corresponding WWN to FC ID association for the oldest entry is lost. Value 255 is accepted from other switches, but cannot be locally configured. read our, Please note that it is recommended to turn, Knowledge This output suggests that the SSH server is disabled or not enabled properly. Command IP Domain-Lookup Use This command allows the router to assume that any non-keyword entered in the command console is supposed to be resolved into an IP address. Cisco Commands Cheat Sheet Almost all Cisco devices use Cisco IOS to operate and Cisco CLI to be managed. Toenable and configure a Cisco router/switch for the SSH server, you must configure SSH parameters. Note FC IDs are enabled by default. The next step is to configure passwords for Telnet and console access. Example: Permit an entire subnet to go anywhere: R-1(config-ext-nacl)# permit ip 192.168.20.0 0.0.0.255 any, R-1(config-ext-nacl)# deny ip any any (this is applied by default if not configured), R-1(config-if)# ip access-group NAME in (evaluate packets coming in to the router), R-1(config-if)# ip access-group NAME out (evaluate packets leaving the router), R-1(config-line)# access-class NAME in (evaluate packets for telnet or SSH), R1(config)# ip access-list extended OUTBOUND-TRAFFIC, R1(config-ext-nacl)# permit tcp any any reflect TCP-TRAFFIC, R1(config-ext-nacl)# permit udp any any reflect UDP-TRAFFIC, R1(config-ext-nacl)# permit icmp any any reflect ICMP-TRAFFIC, R1(config)# ip access-list extended EVALUATE-INBOUND, R1(config-ext-nacl)# evaluate TCP-TRAFFIC, R1(config-ext-nacl)# evaluate UDP-TRAFFIC, R1(config-ext-nacl)# evaluate ICMP-TRAFFIC, R1(config-if)# ip access-group OUTBOUND-TRAFFIC out, R1(config-if)# ip access-group EVALUATE-INBOUND in, R-1(config-time-range)# periodic Monday Wednesday Friday 8:00 to 17:00, R-1(config)# access-list 133 permit tcp 192.168.20.0 0.0.0.255 any eq telnet time-range MON-WED-FRI, R-1# show access-list (see access lists on this router and # of matches per line), R-1# show access-list NAME (see a specific access list and # of matches per line), R-1(config)# ip dhcp excluded 172.16.2.1 172.16.2.7 (excluded IP range), R-1(config)# ip dhcp pool LAN-2 (name this DHCP pool), R-1(dhcp-config)# network 172.16.2.0 255.255.255.128 (entire network range), R-1(dhcp-config)# default-router 172.16.2.1 (address on router port), R-1(dhcp-config)# dns-server 140.198.8.14 (DNS server can have up to 4), R-1(dhcp-config)# domain-name MCC.COM (optional domain name), R-1(dhcp-config)# lease-time 5 (optional - change to 5 day lease, 1 day is default), R-3(config)# interface fastethernet 0/1 (interface for network with DHCP clients), R-3(config-if)# ip helper-address 192.168.15.2 (address where DHCP server is), R-1# show ip dhcp binding (see what IP addresses are assigned & MAC addresses), DOS-PROMPT>ipconfig /release (remove dynamically assigned IP information on PC), DOS-PROMPT>ipconfig /renew (get new IP address from DHCP server), Configuring DHCP for IPv6 Stateless Address Auto-Configuration (SLAAC), R1(config)# ipv6 unicast routing (make sure IPv6 is activated), R1(config)# ipv6 dhcp pool LAN-10-STATELESS (create pool for addresses and DNS), R1(dhcpv6-config)# dns-server 2001:345:ACAD:F::5 (IPv6 DNS server address), R1(dhcpv6-config)# domain-name cisco.com (optional domain name), R1(config-if)# ipv6 address 2001:A1B5:C13:10::1/64 (configure IPv6 address), R1(config-if)# ipv6 dhcp server LAN-10-STATELESS (look to this DHCP pool), R1(config-if)# ipv6 nd other-config-flag (enable IPv6 Neighbor Discovery), Configuring DHCP for IPv6 Stateful Address Auto-configuration, R1(config)# ipv6 dhcp pool LAN-10-STATEFUL (create pool for addresses and DNS), R1(dhcpv6-config)# address prefix 2001:D7B:CAF:10::/64 lifetime infinite infinite, R1(config-if)# ipv6 address 2001:D7B:CAFE:10::1/64 (configure IPv6 address), R1(config-if)# ipv6 dhcp server LAN-10-STATEFUL (look to this DHCP pool), R1(config-if)# ipv6 nd managed-config-flag (enable IPv6 Neighbor Discovery), R-3(config-if)# ip dhcp relay destination 2001:A123:7CA1::15 (IPv6 DHCP server address).
