Allied Telesis AT-8600, RAPIER I Route Update Queue Length, Set switch hwrouteupdate, New command

Software Version 2.8.1 29

Route Update Queue Length

When hardware learning delay is enabled (the default), the switch learns new routes in software, then places them into a queue for adding to its hardware routing table. Defaults have been set for the maximum number of entries in the queue, and depend on the amount of memory installed on the switch, as shown in the following table:

Memory Size (Mbytes)	Default length	Maximum possible length
	(number of entries)	(number of entries)
up to 128	200000	200000
129-256	1000000	1500000
more than 256	3000000	4000000

You can alter the length of the queue, by using the following new command to specify the maximum number of entries in the queue:

set switch hwrouteupdate=1..maximum

The maximum depends on the amount of memory on the switch, as shown in the table above.

The purpose of this feature is to enable you to tune the balance between the memory that the route update process uses, and the speed with which large route updates are processed.

Output of the show switch command has been expanded to display information about the queue settings.
