Displaying ARP entries
You can display the ARP cache and the static ARP table. The ARP cache contains entries for devices
attached to the device. The static ARP table contains the user-configured ARP entries. An entry in
the static ARP table enters the ARP cache when the entry’s interface comes up.
The tables require separate display commands.
Displaying the ARP cache
To display the contents of the ARP cache, enter the following command at any CLI level.
Syntax: show arp [ethernet <slot/port> | mac-address <xxxx.xxxx.xxxx> [<mask>] | <ip-addr>
[<ip-mask>]] [<num>] [| begin <expression> | exclude <expression> | include
<expression>]
The ethernet
<slot>/<portnum>
parameter lets you restrict the display to entries for a specific
port.
The mac-address
<xxxx.xxxx.xxxx>
parameter lets you restrict the display to entries for a specific
MAC address.
The
<mask>
parameter lets you specify a mask for the mac-address <xxxx.xxxx.xxxx> parameter, to
display entries for multiple MAC addresses. Specify the MAC address mask as “f”s and “0”s, where
“f”s are significant bits.
The
<ip-addr>
and
<ip-mask>
parameters let you restrict the display to entries for a specific IP
address and network mask. Specify the IP address masks in standard decimal mask format (for
example, 255.255.0.0).
NOTE
The
<ip-mask>
parameter and <mask> parameter perform different operations. The <ip-mask>
parameter specifies the network mask for a specific IP address, whereas the <mask> parameter
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.
