Displays the IP Address Resolution Protocol (ARP) table. You can filter the display by IP address, MAC address, This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, X670-G2, X690, X695, X870, 5320, 5420, 5520 series switches., or permanent entries.
| ip_addr | Specifies an IP address. |
| mac | Specifies a MAC address. |
| vlan_name | Specifies a VLAN name. |
| vlan_list | Specifies a VLAN list of IDs. |
| permanent | Specifies permanent entries. |
| port | Show entries for a specific port. |
| port | Show only entries for this port number. |
| vr_name | Specifies a VR or VRF. |
Show all entries, except for proxy entries.
If you do not specify a VR or VRF, the command applies to the current VR context.
The show output displays the following information:
| ARP address check | Whether IP ARP checking is enabled or disabled. IP ARP checking verifies if the ARP request‘s source address is in the receiving interface‘s subnet. |
| ARP refresh | Whether ARP refresh is enabled or disabled. ARP refresh is performed when an ARP entry‘s age is three-fourths of the timeout value. |
| Dynamic entries | The number of dynamic (learned ARP) entries in the table. |
| Pending entries | The number of sent ARP requests that have not yet received a response. |
| Static entries | The number of configured (static ARP) entries in the table. |
| Timeout | Timeout value for a dynamic (learned) ARP entry. |
| ARP Global Settings | |
| Max Entries | Maximum number of ARP entries. |
| Max Pending Entries | Maximum number of pending ARP entries. |
| Max Proxy Entries | Maximum number of proxy ARP entries. |
The following example displays the IP ARP table for the current VR or VRF context:
