Showing the Running-Conguration for an Interface
To view the conguration for any interface, use the following command.
• Show the currently running conguration for the specied 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 1-GigabitEthernet interface, enter the keyword GigabitEthernet then the slot/port information.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet 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
Dell#show run int gigabitethernet 2/2
!
interface GigabitEthernet 2/2
no ip address
ipv6 address 3:4:5:6::8/24
shutdown
Dell#
Clearing IPv6 Routes
To clear routes from the IPv6 routing table, use the following command.
• Clear (refresh) all or a specic route from the IPv6 routing table.
EXEC mode
clear ipv6 route {* | ipv6 address prefix-length}
• *: all routes.
• ipv6 address: the format is x:x:x:x::x.
• mask: the prex 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 trac loss. You can
congure the system to keep the learnt neighbor discovery entries stateless so that the ND entries do not time out. To congure 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:
INTERFACE
IPv6 Routing
