show arp
This command displays the Address Resolution Protocol (ARP) cache. The displayed results are
not the total ARP entries. To view the total ARP entries, the operator should view the
show arp
results in conjunction with the
show arp switch
results.
Format
show arp
Mode
Privileged EXEC
Age Time (seconds)
Is the time it takes for an ARP entry to age out. This value was
configured into the unit. Age time is measured in seconds.
Response Time (seconds)
Is the time it takes for an ARP request timeout. This value
was configured into the unit. Response time is measured in sec-
onds.
Retries
Is the maximum number of times an ARP request is retried. This
value was configured into the unit.
Cache Size
Is the maximum number of entries in the ARP table. This value
was configured into the unit.
Dynamic Renew Mode
Displays whether the ARP component automatically attempts to
renew dynamic ARP entries when they age out.
Total Entry Count Current / Peak
Field listing the total entries in the ARP table and the
peak entry count in the ARP table.
Static Entry Count Current / Max
Field listing the static entry count in the ARP table and
maximum static entry count in the ARP table.
The following are displayed for each ARP entry.
IP Address
Is the IP address of a device on a subnet attached to an existing
routing interface.
MAC Address
Is the hardware MAC address of that device.
Interface
Is the routing slot/port associated with the device ARP entry.
Type
Is the type that was configured into the unit. The possible values
are Local, Gateway, Dynamic and Static.

IP Routing
This chapter provides a detailed explanation of the IP Routing commands. The commands are
divided by functionality into the following different groups:
•
Show commands are used to display switch settings, statistics and other information.
•
Configuration Commands are used to configure features and options of the switch. For every
configuration command there is a show command that will display the configuration setting.
•
Copy commands are used to transfer configuration and informational files to and from the
switch.
routing
This command enables routing for an interface.
