IPv6 commands
clear ipv6 neighbors
Deletes all entries in the IPv6 neighbor discovery cache or neighbors of a specic interface. Static entries are not removed.
Syntax
clear ipv6 neighbors [vrf vrf-name] [ipv6-address | interface]
Parameters
• vrf vrf-name — (Optional) Enter vrf then the name of the VRF to clear the neighbor corresponding to
that VRF. If you do not specify this option, the neighbors in the default VRF clear.
• ipv6-address — Enter the IPv6 address of the neighbor in the x:x:x:x::x format to remove a specic IPv6
neighbor. The :: notation species successive hexadecimal elds of zero.
•
interface interface — To remove all neighbor entries learned on a specic interface, enter the keyword
interface then the interface type and slot/port or number information of the interface:
– For a 10-Gigabit Ethernet interface, enter TenGigabitEthernet then the slot/port/subport[/subport]
information.
– For a 40-Gigabit Ethernet interface, enter fortyGigE then the slot/port information.
– For a port channel interface, enter port-channel then a number.
