Showing the Running-Configuration for an Interface To view the configuration for any interface, use the following command. • Show the currently running configuration for the specified interface. EXEC mode show 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 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 Command DellEMC#show run int Te 2/2 ! interface TenGigabitEthernet 2/2 no ip address ipv6 address 3:4:5:6::8/24 shutdown DellEMC# Clearing IPv6 Routes To clear routes from the IPv6 routing table, use the following command. • Clear (refresh) all or a specific route from the IPv6 routing table. EXEC mode clear ipv6 route [vrf vrf-name] {* | ipv6 address prefix-length} - vrf vrf-name:(OPTIONAL) name of the VRF. - *: 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 a colon (:). Omitting zeros is accepted as described in Addressing. Disabling ND Entry Timeout When a peer system warmboots or performs an ISSU, the ND entries in the local system may time out resulting in traffic loss. You can configure the system to keep the learnt neighbor discovery entries stateless so that the ND entries do not time out. To configure the system to keep the learnt neighbor discovery entries stateless, follow these steps: • Disable the ND timer: INTERFACE ipv6 nd disable-reachable-timer • To reenable the ND timer, use the no form of the command: IPv6 Routing 473
