If no VLAN is specified (which is equal to entering the vlan all keywords after the policy-name argument),
RA guard traffic from all VLANs on the port is analyzed.
If specified, the VLAN parameter is either a single VLAN number from 1 through 4094 or a range of VLANs
described by two VLAN numbers, the lesser one first, separated by a dash. Do not enter any spaces between
comma-separated vlan parameters or in dash-specified ranges; for example, vlan 1-100,200,300-400.
Examples
In the following example, the IPv6 RA guard feature is applied on GigabitEthernet interface 0/0:
switch(config)# interface GigabitEthernet 0/0
switch(config-if)# ipv6 nd raguard attach-policy
