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>]
For information on the command syntax, refer to the syntax of the show arp command under
“Displaying the ARP cache” on page 224.
Displaying the forwarding cache
To display the IP Forwarding Cache for directly connected hosts, enter the following command.
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
information” on page 221. To change the ARP aging interval, refer to
“Changing the ARP aging period” on page 190.
NOTE: Static entries do not age out.
Port The port on which the entry was learned.
