Section VII: Internet Protocol Routing
Setting the ARP Cache Timeout
The ARP cache contains mappings of IP addresses to physical addresses
for hosts where the switch has recently routed packets. To have an entry
in the ARP cache, a host must have attempted to access another host,
and it must have found the physical address by using the ARP protocol.
(You must use the command line interface to view the ARP cache.)
This procedure sets the ARP cache timeout value. The timer prevents the
ARP table from becoming full with inactive entries. An entry that is not
used for the length of the timeout period is designated as inactive and is
deleted from the table.
To set the ARP cache timeout value, perform the following procedure:
1. From the Main Menu, type
5
to select System Administration.
2. From the System Administration menu, type
2
to select System
Configuration.
3. Type
8
to select ARP Cache Timeout.
The following prompt is displayed:
Enter your new value -> [1 to 260000] 150
4. Enter a new value for the ARP cache timeout value. The range is 1 to
260000 seconds. The default is 150 seconds.
5. To permanently save your change, return to the Main Menu and type
S
to select Save Configuration Changes.
