Chapter 8 Managing PNNI Nodes and PNNI Routing
Managing Priority Routing
Configuring Priority Routing for an SPVC
Once priority routing has been set up on a node, you can prioritize the node’s SPVCs. A connection’s
priority is designated during the SPVC master end setup with the addcon command. (See Chapter 4,
“Preparing Service Modules for Communication.” )
The following command example defines a port as the master side of an SPVC with a routing priority of
3.
mgx8830a.1.PXM.a > addcon 3 101 101 1 1 -slave -rtngprio 3
4700918100000000001A531C2A00000101180300.101.101
master endpoint added successfully
master endpoint id : 4700918100000000107B65F33C0000010A180300.101.101
Note For VISM cards, configuring the connection priority can only be done through SNMP. This CLI is not
currently supported for VISM.
-bwincr The increment for the cell rate between the upper and lower bounds of each
intermediate bandwidth group. For example, an increment of 2000 means that a
range starting at 10000 cps ends at 12000 cps. This increment does not apply to
the following groups:
• The group with the lowest bandwidth requirements: for this group, the range
is determined by the value for bwstart.
• The group with the highest bandwidth requirements: for this group, the range
is what remains after computations based on the following values:
–
bwstart
–
bwincr
Range: 1–500000
Default: 1000
-pribuf The priority buffer is a time counter. It counts down to the moment when PNNI
prioritizes all buffered connections for routing. A connection is buffered due to an
event that causes PNNI to re-route the connection. The routing events are:
• Interface with a master endpoint comes up.
• Routed SPVC or SPVP is released (or failed).
• SPVC or SPVP is created.
• Route optimization begins.
Range: 0–600, in units of 0.1 seconds (0–60 seconds)
Default: 0
-nodebuf The node buffer is a time counter. It counts down the time to wait before PNNI
starts routing connections. Down-counting begins when the first PNNI logical port
comes up. The buffer operates once, after node start-up or node reset.
Range: 0–3000, measured in units of 0.1 seconds (0–300 seconds)
Default: 0
