- mc (Optional) Keyword that specifies the maximum cost (maxcost): a value that creates
a routing priority. If you do no t s pe cif y th is op ti onal parameter, the connectio n
defaults to having the highest routing priority. Therefore, the maxcost parameter lets
you lower the priority of a connection—but only in regards to finding a route for it.
The range for maxcost is 0–2147483647. The PXM45 does not use a particular route
if the cost for the route exceeds th e m axcost.
The cost of a route depends on a cost-per-link specified through the cnfpnni-intf
command. The cost-per-link app lie s to at the egress a port for all c on n ect io n s o f a
particular service type. For examp le , the cost-per-link is the same f o r all V B R.1
connections that PN N I co ntrols on a given port, bu t t his cost can differ fr om al l
UBR.1 connections on the same port.
For a route under consideration , t he co s t is t he sum of all the cost-per-links at eac h
egress in the forward and backward directions along the entire route. In a one-link
route, for example, the cost is the sum of the cost-per-links at two ports.
To illustrate further with a four-link route:
1. You s pe c if y a ma xcost of 100000.
2. The route under consideration by the switching fa bric has four links for a total of
eight egress points.
3. The cost-per-link at six ports is 5040 (the default in cnfpnni-intf), and the cost
per link at two ports is 10000.
The node would use the route because the resulting cost of 50240 is less than the
maxcost of 100000.
Note that you can specify no limit for a service type by entering a cost-per-link of -1
through cnfpnni-intf. A -1 cost-per-link makes maxcost meaningless.
