This command is used to add static entries to the Neighbor Binding table. Static
entries can be configured regardless the port role.
If the entry (dynamic or static) already exists, the new static entry overrides the
existing one.
If the Neighbor Binding table overflows, the static entry is not added.
Example
The following example adds a static entry:
switchxxxxxx(config)# ipv6 neighbor binding static ipv6 2001:600::1 vlan 100
interface gi11 mac 00BB.CC01.F500

To enable the IPv6 Source Guard feature on a VLAN, use the ipv6 source guard
command in VLAN Configuration mode. To return to the default, use the no form of
this command.
