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.

Table 9-5 Port Connection Allocations, Useful Default Values

		Useful
		Default
Connection Type	Variable	Value	cnfrsrc cmd parameter
AutoRoute LCNs	a(x)	256	maxpvclcns
Minimum VSI LCNs for partition 1	n1(x)	512	minvsilcns
Maximum VSI LCNs for partition 1	m1(x)	7048	maxvsilcns
			Different types of BXM cards
			support different maximums. If
			you enter a value greater than
			the allowed maximum, a
			message is displayed with the
			allowable maximum

Here, a(x) = 256, n1(x) = 512, and m1(x) = 16384.
