SHOW ARP
show arp
Overview Use this command to display entries in the ARP routing and forwarding table—the
ARP cache contains mappings of IP addresses to physical addresses for hosts. To
have a dynamic entry in the ARP cache, a host must have used the ARP protocol to
access another host.
For information on filtering and saving command output, see the “Getting Started
with AlliedWare Plus” Feature Overview and Configuration Guide .
Syntax
show arp [security [interface [< interface-list >]]
show arp [statistics [detail][interface [< interface-list >]]
Syntax (VRF-lite) show arp [global|security|vrf < vrf-name >]

Usage Running this command with no additional parameters will display all entries in the
ARP routing and forwarding table.
With VRF-lite configured, and no additional parameters entered, the command
output displays all entries, listed by their VRF instance. By adding either a specific
VRF instance or global parameter entry, you can selectively list ARP entries by their
membership of a specific VRF instance.
Example To display all ARP entries in the ARP cache, use the following command:
awplus# show arp
