Showing the Running-Configuration for an InterfaceTo view the configuration for any interface, use the following command.• Show the currently running configuration for the specified interface.EXEC modeshow running-config interface type {slot/port}Enter the keyword interface then the type of interface and slot/port information:• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port[/subport] information.• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.• For the Management interface on the stack-unit, enter the keyword ManagementEthernet then the slot/port information.Example of the show running-config interface CommandDell#show run int Te 2/2!interface TenGigabitEthernet 2/2no ip addressipv6 address 3:4:5:6::8/24shutdownDell#Clearing IPv6 RoutesTo clear routes from the IPv6 routing table, use the following command.• Clear (refresh) all or a specific route from the IPv6 routing table.EXEC modeclear ipv6 route {* | ipv6 address prefix-length}• *: all routes.• ipv6 address: the format is x:x:x:x::x.• mask: the prefix length is from 0 to 128.NOTE: IPv6 addresses are normally written as eight groups of four hexadecimal digits, where each group is separated by acolon (:). Omitting zeros is accepted as described in Addressing.Disabling ND Entry TimeoutWhen a peer system warmboots or performs an ISSU, the ND entries in the local system may time out resulting in traffic loss. You canconfigure the system to keep the learnt neighbor discovery entries stateless so that the ND entries do not time out. To configure thesystem to keep the learnt neighbor discovery entries stateless, follow these steps:• Disable the ND timer:INTERFACEipv6 nd disable-reachable-timer• To reenable the ND timer, use the no form of the command:INTERFACEIPv6 Routing 467
