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.

Displaying the ARP cache
To display the contents of the ARP cache, enter the following command at any CLI level.

Syntax: show arp [ethernet | mac-address [] |

[]] []

The parameter lets you restrict the display to entries for a specific port.

The mac-address parameter lets you restrict the display to entries for a specific
MAC address.

The parameter lets you specify a mask for the mac-address 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.

Status

The link status of the interface. If you have disabled the interface with the disable command,
the entry in the Status field will be “administratively down”. Otherwise, the entry in the Status
field will be either “up” or “down”.

Protocol

Whether the interface can provide two-way communication. If the IP address is configured, and
the link status of the interface is up, the entry in the protocol field will be “up”. Otherwise the
entry in the protocol field will be “down”.
