Configuring Priority Routing on a Connection
Configuring Priority Routing on a Connection
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 the
“Configuring the Master Side of SPVCs and SPVPs” section in Chapter 6, “Provisioning AXSM
Communication Links.”).
The following command example defines a port as the master side of an SPVC with a routing priority of
3.
pop20one.10.AXSM.a > addcon 3 101 101 1 1 -slave -rtngprio 3
4700918100000000001A531C2A00000101180300.101.101
master endpoint added successfully
master endpoint id : 4700918100000000107B65F33C0000010A180300.101.101
Note If you are setting up priority routing on a node that already has established SPVCs, their routing priority
is set to 8 by default. You can change the routing priority on an established connection with the cnfcon
command. (See the next section“Modifying SPVC Priority Routing Configuration”)
-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:
• An interface with a master endpoint comes
up.
• A routed SPVC or SPVP is released (or
failed).
• An 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
