General AXSM Configuration Procedures
In the following example, the user adds IMA port 8 to IMA group 1. The port operates as an NNI and
uses the default SCT, with a guaranteed minimum and maximum bandwidth rate of 100 cps.
M8850_LA.12.AXSME.a > addimaport 8 1 100 100 0 2
Step 5 To display a list of all ports configured on the AXSM card, enter the dspports command.
Port numbers are listed in the ifNum (interface number) column. To view information on a particular
port, note the number of that port.
Partitioning Port Resources between Controllers
After you add a line or trunk port, you need to define how the port resources are used by the PNNI and
MPLS controllers. You can assign all resources to one controller, or you can divide the port resources
between both controllers. You can assign the following port resources to controllers:
• Range of VPI values
• Range of VCI values
• Guaranteed percent of bandwidth for ingress and egress directions
• Minimum and maximum number of connections
Note Each switch, card, and port supports a maximum number of connections. Use the partition definition to
control how available connections are distributed within the switch. Although you can enable the
maximum number of connections on all ports, two or three very busy ports could use all available
connections and disable communications on all other ports.
The port resources are defined as a group in a controller partition, which is dedicated to a single port
controller. You must define one controller partition for each controller type you want to support, and you
must configure one resource partition for each port that uses a controller. Figure 3-4 presents a simplified
view of the relationship between the port controller, controller partition, and resource partitions. Within
the figure, note that the single controller partition connects to the port controller and to the resource
partitions.
-vpi <vpi> The Virtual Path Identifier (VPI), which is used in this case to configure the
interface as a virtual trunk. The ranges are as follows:
• 1–255 VUNI
• 1– 4095 VNNI
-minvpi <minvpi> The minimum VPI. The ranges are as follows:
• 0–255 EVUNI
• 0–4095 for EVNNI
-maxvpi <maxvpi> The maximum VPI. The ranges are as follows:
• 0–255 EVUNI
• 0–4095 for EVNNI
