Concept Guide

– 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 2/2/1
!
interface TenGigabitEthernet 2/2/1
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 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
no ipv6 nd disable-reachable-timer
The following example shows how to disable the ND timer.
DellEMC(conf-if-fo-1/1/1)#ipv6 nd disable-reachable-timer
Conguring IPv6 RA Guard
The IPv6 Router Advertisement (RA) guard allows you to block or reject the unwanted router advertisement guard messages that arrive at
the network device platform.
To congure the IPv6 RA guard, perform the following steps:
1 Congure the terminal to enter the Global Conguration mode.
EXEC Privilege mode
