Displaying IP configuration information and statistics

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.

This display shows the following information. The number in the left column of the CLI display is
the row number of the entry in the ARP cache. This number is not related to the number you assign
to static MAC entries in the static ARP table.

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

Displays...

IP Address

The IP address of the device.

MAC Address

The MAC address of the device.

Type

The ARP entry type, which can be one of the following:

Dynamic – The Layer 3 Switch learned the entry from an incoming packet.

Static – The Layer 3 Switch loaded the entry from the static ARP table when the device for the
entry was connected to the Layer 3 Switch.

DHCP – The Layer 3 Switch learned the entry from the DHCP binding address table.

NOTE: If the type is DHCP, the port number will not be available until the entry gets resolved

through ARP.

Age

The number of minutes the entry has remained unused. If this value reaches the ARP aging
period, the entry is removed from the table.
To display the ARP aging period, refer to

“Displaying global IP configuration information”

on

page 493. To change the ARP aging interval, refer to

“Changing the ARP aging period”

on

page 460.
NOTE: Static entries do not age out.

Port

The port on which the entry was learned.
NOTE: If the ARP entry type is DHCP, the port number will not be available until the entry gets

resolved through ARP.

Status

The status of the entry, which can be one of the following:

Valid – This a valid ARP entry.

Pend – The ARP entry is not yet resolved.
