Displaying IP information

NOTE
The <ip-mask> parameter and
parameter specifies the network mask for a specific IP address, whereas the
provides a filter for displaying multiple MAC addresses that have specific values in common.
The <num> parameter lets you display the table beginning with a specific entry number.
NOTE
The entry numbers in the ARP cache are not related to the entry numbers for static ARP table entries.
This display shows the following information. The number in the left column of the CLI display is
the row number of the entry in the ARP cache. This number is not related to the number you assign
to static MAC address entries in the static ARP table.
Displaying the static ARP table
To display the static ARP table, enter the following command at any CLI level.
This example shows two static entries. Note that since you specify an entry’s index number when
you create the entry, it is possible for the range of index numbers to have gaps, as shown in this
example. The entry number you assign to a static ARP entry is not related to the entry numbers in
the ARP cache.
Syntax: show ip static-arp [ethernet <slot>/<portnum> | mac-address <xxxx.xxxx.xxxx> [<mask>]
| <ip-addr> [<ip-mask>]] [<num>] [| begin <expression> | exclude <expression> |
include <expression>]

IP Address
The IP address of the device.
MAC Address
The MAC address of the device.
Type
The type, which can be one of the following:
•
Dynamic – The device learned the entry from an incoming packet.
•
Static – The device loaded the entry from the static ARP table when the
device for the entry was connected to the device.
Age
The number of minutes the entry has remained unused. If this value
reaches the ARP aging period, the entry is removed from the table.
To display the ARP aging period, refer to
“Displaying global IP configuration
on page 222. To change the ARP aging interval, refer to
“Changing the ARP aging period”
