Displaying IP configuration information and statistics
26
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.
Method Whether the IP address has been saved in NVRAM. If you have set the IP address for the
interface in the CLI or Web Management Interface, but have not saved the configuration, the
entry for the interface in the Method field is “manual”.
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”.
