Installation and Getting Started Guide
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).
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.
Table 6.11: 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 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 table.
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 on which the entry was learned.
USING THE WEB MANAGEMENT INTERFACE
To display the IP ARP cache:
1. Log on to the device using a valid user name and password for read-only or read-write access. The System
configuration panel is displayed.
2. Click on the plus sign next to Monitor in the tree view to list the monitoring options.
3. Click on the ARP Cache
link to display the IP ARP cache.
This display shows the following information.
