cnfpri-routing Command Parameters
Parameter
Description
-bwgrps
Bandwidth groups.
-bwstart
The value for bwstart is the highest cell rate in the lowest-speed bandwidth
group. The number of bandwidth groups is fixed at 50.
Range: 1–500000
Default: 5000
-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 as follows:
•
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
