Displaying ARP Entries
You can display the ARP cache and the static ARP table. The ARP cache contains entries for devices attached to
the Layer 3 Switch. 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 or Web management options.
Displaying the ARP Cache
To display the ARP cache, use one of the following methods.
USING THE CLI
To display the contents of the ARP cache, enter the following command at any CLI level:
BigIron# show arp
Total number of ARP entries: 5
IP Address
1 207.95.6.102
2 207.95.6.18
3 207.95.6.54
4 207.95.6.101
5 207.95.6.211
Syntax: show arp [ethernet <portnum> | mac-address <xxxx.xxxx.xxxx> [<mask>] | <ip-addr> [<ip-mask>]]
[<num>]
The ethernet <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.
