-mc The maximum cost (maxcost) creates a routing priority. (PNNI does not use a route if the
cost for the route exceeds the maxcost.) If you do not specify this optional parameter, the
connection 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 0–4294967295, and the default is 4294967295.
The cost of a route (not the maxcost of the connection) depends on a cost-per-link
specified through the cnfpnni-intf command. The cost-per-link applies at the egress of
a port for all connections of a particular service type. For example, the cost-per-link is
the same for all VBR.1 connections that PNNI controls on a given port, but this cost can
differ from all UBR.1 connections on the same port.
For a route under consideration, the cost is the sum of all the costs-per-link at each 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 p ec i fy a maxcost of 100000.
2. A route under consideration by PNNI has four links for a total of eight egress points.
3. The cost-per-link at six of the 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.
Default: 4294967295
Note To return maxcost to the default, type -mc 4294967295. Setting maxcost to this
value makes maxcost meaningless and causes PNNI to ignore this metric when
making routing decisions.
-segep OAM segment endpoint: Enter a 1 to enable or a 0 to disable.
-lputil Local Percentage Utilization
Range: 1–100
Default: 100
-rputil Remote Percentage Utilization
Range: 1–100
Default: 100
-rtngprio The routing priority for the connection. Range: 1–15. 0 is reserved for control
connections, and 1 is reserved for IP to CWM. Default: 8
