Showing The Running-Configuration For An Interface; Clearing Ipv6 Routes; Disabling Nd Entry Timeout - Dell S3048-ON Configuration Manual

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 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

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 {* | 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 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:
