DETAILED STEPS
PurposeCommand or Action
Enters the global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
[no] ipv6 neighbor binding [vlan vlan-id {ipv6-address interface
interface_type stack/module/port hw_address [reachable-lifetimevalue
Step 2
[seconds | default | infinite] | [tracking{ [default | disable] [
reachable-lifetimevalue [seconds | default | infinite] | [enable
[reachable-lifetimevalue [seconds | default | infinite] | [retry-interval
{seconds| default [reachable-lifetimevalue [seconds | default | infinite]
} ]
Example:
Switch(config)# ipv6 neighbor binding
Specifies the maximum number of entries
that are allowed to be inserted in the
binding table cache.
[no] ipv6 neighbor binding max-entries number [mac-limit number |
port-limit number [mac-limit number] | vlan-limit number [ [mac-limit
number] | [port-limit number [mac-limitnumber] ] ] ]
Example:
Switch(config)# ipv6 neighbor binding max-entries 30000
Step 3
Enables the logging of binding table main
events.
ipv6 neighbor binding logging
Example:
Switch(config)# ipv6 neighbor binding logging
Step 4
Exits global configuration mode, and
places the router in privileged EXEC
mode.
exit
Example:
Switch(config)# exit
