The ARP Table Configuration page contains the following fields: • Age Time (secs) - Enter the value you want the switch to use for the ARP entry ageout time. You must enter a valid integer, which represents the number of seconds it takes for an ARP entry to age out. The range for this field is 15 to 21600 seconds. The default value for Age Time is 1200 seconds. • Response Time (secs) - Enter the value you want the switch to use for the ARP response timeout. You must enter a valid integer, which represents the number of seconds the switch waits for a response to an ARP request. The range for this field is 1 to 10 seconds. The default value for Response Time is 1 second. • Retries - Enter an integer which specifies the maximum number of times an ARP request is retried. The range for this field is 0 to 10. The default value for Retries is 4. • Cache Size - Enter an integer which specifies the maximum number of entries for the ARP cache. The range for this field is 256 to 896. The default value for Cache Size is 896. • Dynamic Renew - This controls whether the ARP component automatically attempts to renew ARP Entries of type Dynamic when they age out. The default setting is Enable. • Total Entry Count - Total number of Entries in the ARP table. • Peak Total Entries - Highest value reached by Total Entry Count. This counter value is restarted whenever the ARP table Cache Size value is changed. • Active Static Entries - Total number of Active Static Entries in the ARP table. • Configured Static Entries - Total number of Configured Static Entries in the ARP table. • Maximum Static Entries - Maximum number of Static Entries that can be defined. • Remove from Table - Allows you to remove certain entries from the ARP Table. The choices listed specify the type of ARP Entry to be deleted: - All Dynamic Entries - All Dynamic and Gateway Entries - Specific Dynamic Gateway Entry - Specific Static Entry The ARP Table displays at the bottom of the page, and contains the following fields: • IP Address - The IP address of a device on a subnet attached to one of the switch's routing interfaces. • MAC Address - The unicast MAC address for the device. The format is six two-digit hexadecimal numbers separated by colons, for example 00:06:29:32:81:40. • VLAN ID - The routing interface associated with the ARP entry. • Type - The type of the ARP entry. • Age - Age since the entry was last refreshed in the ARP Table. The format is hh:mm:ss. Configuring Routing 455
