Configuring Connection Policing

The BPX Command Line Interface (CLI) and Cisco WAN Manager accept the same connection policing
and bandwidth parameters as in previous releases for both rt-VBR and nrt-VBR service.
The displayed addcon parameter prompts for both rt-VBR and nrt-VBR connections are the same:

Description: "Default nrt-VBR 1000 "
Default utilization for voice traffic is 100 percent.
For rt-VBR connections, all nodes must be running at least Rel. 9.2.20. The user interface will
block the addition of rt-VBR connections in a network running pre-9.2.20 SWSW.
BXM and UXM (IGX switch) cards can terminate rt-VBR connections and support rt-VBR queues.
On the BPX switch, BXM and BNI trunks support rt-VBR queues
On the IGX switch, only UXM trunks support rt-VBR queues.
You can add both rt-VBR and nrt-VBR connections.The parameter prompts are the same for both
rt-VBR and nrt-VBR, except for Trunk Cell Routing Restriction prompt. (For rt-VBR connections,
the "Trunk Cell Routing Restriction" prompt will not display because rt-VBR traffic should be
routed over only ATM trunks; rt-VBR traffic should not be routed over FastPacket trunks.)
With release 9.3, rt-vbr is supported on 2- and 3-segment connections, but only on IGX feeders and
UXM endpoints. For example: the UXM card on the IGX switch (2 segment: CPE to IGX feeder
UXM to BXM to BXM to CPE) or (3 segment: CPE to IGX feeder UXM to BXM to BXM to IGX
feeder UXM to CPE).
