Allied Telesis AR44xS series manual Route Update Queue Length CR00010196, Memory Size Mbytes

Route Update Queue Length (CR00010196) 74

Route Update Queue Length (CR00010196)

When hardware learning delay is enabled (the default), the switch learns new routes in software, then places them into a queue for adding them 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 (number of entries)	Maximum possible length (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.

Output of the show switch command has been expanded to display information about the queue settings (Figure 3, Figure 4, Table 1).
