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:
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 [<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.
Table 16.10: CLI Display of ARP Cache
This Field... Displays...
IP Address 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 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.
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, see “Displaying Global IP
Configuration Information” on page 16-58. To change the ARP aging
interval, see “Changing the ARP Aging Period” on page 16-27.
Note: Static entries do not age out.
Port The port on which the entry was learned.
