Table 6.12: Web Display of ARP Cache – routing switch

 

 

 

This Field...

 

Displays...

 

 

 

Node

 

The IP address of the device.

 

 

 

MAC Address

 

The MAC address of the device.

 

 

 

Type

 

The type, which can be one of the following:

 

 

• Dynamic – The routing switch learned the entry from an incoming

 

 

packet.

 

 

• Static – The routing switch loaded the entry from the static ARP

 

 

table when the device for the entry was connected to the routing

 

 

switch.

 

 

 

Age

 

The number of minutes the entry has remained unused. If this value

 

 

reaches the ARP aging period, the entry is removed from the cache.

 

 

To display the ARP aging period, see “Displaying Global IP

 

 

Configuration Information” on page 6-81.To change the ARP aging

 

 

interval, see “Changing the ARP Aging Period” on page 6-28.

 

 

Note: Static entries do not age out.

 

 

 

Port

 

The port attached to the device the entry is for. For dynamic entries,

 

 

this is the port on which the entry was learned.

 

 

 

Displaying the Static ARP Table

To display the static ARP table instead of the ARP cache, use either of the following methods.

USING THE CLI

To display the static ARP table, enter the following command at any CLI level:

HP9300# show ip static-arp

Static ARP table size: 512, configurable from 512 to 1024

This example shows two static entries. Note that since you specify an entry’s index number when you create the entry, it is possible for the range of index numbers to have gaps, as shown in this example.

NOTE: The entry number you assign to a static ARP entry is not related to the entry numbers in the ARP cache.

Syntax: show ip static-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).
