Reference Guide

• Router mode — When a policy with device role as router is applied on an interface, all the RA packets
are validated based on the configuration information in the policy. Similarly, you can also apply this
mode over any specific VLAN and the validation is performed only for that particular VLAN RA packets.
To configure the IPv6 RA guard, use the following Dell Networking OS commands.
clear ipv6 neighbors
Delete all entries in the IPv6 neighbor discovery cache or neighbors of a specific interface. Static entries
are not removed using this command.
C9000 Series
Syntax
clear ipv6 neighbors [ipv6 address] | interface interface | vrf
vrf name]
Parameters
ipv6-address Enter the IPv6 address of the neighbor in the x:x:x:x::x
format to remove a specific IPv6 neighbor.
NOTE: The :: notation specifies successive hexadecimal
fields of zero.
vrf vrf-name (OPTIONAL) Enter the keyword vrf followed by the name
of the VRF to clear the neighbor corresponding to that VRF.
NOTE: If you do not specify this option, the neighbors in
the default VRF are cleared.
interface interface To remove all neighbor entries learned on a specific
interface, enter the keyword interface then the interface
type and slot/port or number information of the interface:
Enter one of the following keywords with slot/port or
number to clear information about the IPv6 neighbors
learned on the specified interface:
• For a 1–Gigabit Ethernet 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 a 40-Gigabit Ethernet interface, enter the keyword
fortyGigE then the slot/port information.
• For a port-channel interface, enter the keyword port-
channel with a port-channel number. The range of
port-channel numbers is from 1 to 128.
• For a VLAN interface, enter the keywordvlan then a
number from 1 to 4094.
• For a tunnel interface, enter the keyword tunnel.
