Displaying IP configuration information and statistics
Displaying ARP entries
To display the entries the Layer 2 Switch has placed in its ARP cache, enter the show arp command
from any level of the CLI.
Syntax: show arp
This display shows the following information.
Configuration filename The name under which the Layer 2 Switch startup-config file was uploaded or
downloaded during the most recent TFTP access.
Image filename The name of the Layer 2 Switch flash image (system software file) that was
uploaded or downloaded during the most recent TFTP access.
TABLE 190 CLI display of ARP cache
Field Description
Total ARP Entries The number of entries in the ARP cache.
Maximum
capacity
The total number of ARP entries supported on the device.
IP The IP address of the device.
Mac The MAC address of the device.
NOTE: If the MAC address is all zeros, the entry is for the default gateway, but the Layer 2
Switch does not have a link to the gateway.
Port The port on which the entry was learned.
Age The number of minutes the entry has remained unused. If this value reaches the ARP aging
period, the entry is removed from the cache.
VlanId The VLAN the port that learned the entry is in.
NOTE: If the MAC address is all zeros, this field shows a random VLAN ID, since the Layer 2
Switch does not yet know which port the device for this entry is attached to.
