show arp

Example

This example shows how to display the ARP table:

SSA4(su-config)->show arp
FLAGS:    U = Unresolved     S = Static
          L = Local          V = VRRP
          * = Stale          B = Best Guess Interface
          H = Host Interest  2 = Secondary VLAN Entry
          M = Main Router    A = Proxy-All Entry
          X = VxLan          R = VxLan Remote

show arp Output Details

Output...	What it displays...
IP Address	IP address mapped to MAC address.
Hardware Address	MAC address mapped to IP address.
Flags	Route status. Possible values and their definitions include: U – The router is currently attempting to resolve an ARP entry. An ARP resolution packet has been sent but a response has not been received. If a response is not received within three (3) seconds the Unresolved entry will be removed from the ARP table. L – The IP address and hardware address of this entry is the IP address and hardware address assigned to a directly connected interface. V – This is an ARP entry for an interface which is running VRRP. * – The ARP entry is stale (timed out). The entry will remain in the database and will be used by the router for “stale-entry-timeout” seconds. See stale-entry-timeout for more information. S – A permanent (static) entry manually configured. B – Interface was not specified when the static ARP was defined, router will make a best guess. H – Host Interest: The ARP entry has been used for direct communication with the router as opposed to communication between hosts that pass through the router. 2 – Secondary VLAN Entry: The ARP entry belongs to a host on a Secondary VLAN.
Age	Specifies the amount of time the ARP entry has been in the table.
Updated	Specifies the amount of time that has elapsed since this entry was updated.
Interface	The VLAN interface for this entry.
Port	The port name for this entry.
