show ip arp

show ip arp

Displays ARP statistics associated with all Gigabit Ethernet interfaces, with a specified Gigabit Ethernet interface, with a specified host, with a specified IP address, or with a specified MAC hardware address

Syntax: show ip arp [brief] [[gbe bay/slot/port] | [hostname] |
[ip-address] | [mac-address]

gbe bay/slot/port

Identifies a specific Gigabit Ethernet interface on the Avici router.

hostname

The host name of the desired ARP statistics.

ip-address

The four-byte IP address of the desired ARP statistics.

mac-address

The MAC hardware address for the desired ARP statistics

brief

Display summarized information.

Description: Use the show ip arp command to display all ARP entries by interface for this Avici router.

Use the show ip arp gbe bay/slot/port command to display ARP entries for a specified Gigabit Ethernet module interface.

Use the show ip arp hostname command to display ARP entries for the specified host.

Use the show ip arp ip-address command to display ARP entries for the specified IP address.

Use the show ip arp mac-address command to display ARP entries for the specified MAC hardware address.

Use the show ip arp brief command to display a brief version of ARP entry statistics. This command excludes age and retry statistics.

The following table describes the fields in the display:
