Usage Guidelines

This command displays the entries present in the neighbor cache.

The entries displayed can be filtered by IPv6 address, MAC address, or by VLAN. The permanent keyword filters the output to display static entries.

The vr_name indicates the VR or VRF on which the operation is performed. In its absence, the operation applies to VR-Default.


The following example output shows all entries from the neighbor cache:
