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)
up to 128
129-256
more than 256
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.
