clear ipv6 fhs snooping [vlan <1-4059>][ipv6-address WORD<0-46>]

Switch:1> enable
Switch:1>clear ipv6 fhs snooping vlan 1000 ipv6-address 2001:DB8:89ab:cdef:0123:4567:89ab:cdef

The following table defines parameters for the clear ipv6 fhs snooping command.


Variable	Value
ipv6-address `WORD<0-46>`	Specifies the IPv6 address for the binding entry to clear. You cannot specify an address without first specifying the VLAN.
vlan `<1-4059>`	Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1. If you do not specify a VLAN, the command clears all entries.
