cnfrsrc
Description
The following paragraphs describe various configurations of BXM port resources for tag switching.
The first allocation example is using default allocations. The second allocation example describes
more rigorous allocations where default allocations are not applicable.
Useful Default Allocations
Reasonable default values for all ports on all cards are listed in Table 9-5. If these values are not
applicable, then other values may be configured using the cnfrsrc command.
Here, a(x) = 256, n
1
(x) = 512, and m
1
(x) = 16384.
Example:
Configure the VSI partition for port 4.1 by entering the following command:
cnfrsrc 4.1 256 26000 1 e 512 16384 2 15 26000 100000
