150 Configuring and Managing IP Interfaces and Services
320657-A
Changing the Aging Timeout
The aging timeout specifies how long a dynamic entry can remain unused before the software removes the entry from
the ARP table. The default aging timeout is 1200 seconds (20 minutes). The aging timeout does not affect the local
entry, static entries, or permanent entries.
To change the aging timeout, use the following command:
set arp agingtime seconds
You can specify from 0 to 1,000,000 seconds. To disable aging, specify 0.
For example, to disable aging of dynamic ARP entries, type the following command:
23x0# set arp agingtime 0
success: set arp aging time to 0 seconds
Pinging Another Device
To verify that another device in the network can receive IP packets sent by the WSS switch, use the following command:
ping host [count num-packets] [dnf] [flood] [interval time] [size size]
[source-ip ip-addr | vlan-name]
To ping a device that has IP address 10.1.1.1, type the following command:
23x0# ping 10.1.1.1
PING 10.1.1.1 (10.1.1.1) from 10.9.4.34 : 56(84) bytes of data.
64 bytes from 10.1.1.1: icmp_seq=1 ttl=255 time=0.769 ms
64 bytes from 10.1.1.1: icmp_seq=2 ttl=255 time=0.628 ms
64 bytes from 10.1.1.1: icmp_seq=3 ttl=255 time=0.676 ms
64 bytes from 10.1.1.1: icmp_seq=4 ttl=255 time=0.619 ms
64 bytes from 10.1.1.1: icmp_seq=5 ttl=255 time=0.608 ms
--- 10.1.1.1 ping statistics ---
5 packets transmitted, 5 packets received, 0 errors, 0% packet loss
In this example, the ping is successful, indicating that the WSS has IP connectivity with the other device.
(For information about the command options, see the Nortel WLAN Security Switch 2300 Software Command
Reference.)
Note. To reset the ARP aging timeout to its default value, use the set arp agingtime
1200 command.
