Changing the default ARP aging time
The default ARP aging time value is set for 360 minutes. To change this
default aging time use the ip arp timeout command. This command
has the following syntax:
ip arp timeout <minutes>
The <minutes> parameter represents the number of minutes to set for the
new timeout setting. This is a value in the range of 5 to 360.
The following is an example of setting a new default aging time:
5530-24TFD(config)# ip arp timeout 180
The new setting can be confirmed by using the show ip routing
command.
Adding a static ARP entry to a VLAN
To add a static ARP entry to a VLAN, use the ip arp command. This
command has the following syntax:
ip arp ip <ip_address> mac <mac_address> port <port_number>
vid <vid_number>
The following table outlines the parameters of this command
ip arp parameters
Parameter Description
ip_address The IP address of the entry.
mac_address The MAC address of the entry.
