Displaying IP configuration information and statistics
To display detailed IP information for a specific interface, enter a command such as the following.
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 interface comes up.
The tables require separate display commands or Web management options.
Displaying the ARP cache
To display the contents of the ARP cache, enter the following command at any CLI level.
Syntax: show arp [ethernet [<slotnum>/]<portnum> | mac-address <xxxx.xxxx.xxxx> [<mask>] |
<ip-addr> [<ip-mask>]] [<num>]
The <slotnum> parameter is required on chassis devices.
The <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).
