If these values are less than the minimum values supported on a given card, the command line interface
will not allow you to set them until you have disabled policing. (A prompt will let you know about this
limitation.)
Please refer to Table 5-1 for a list of cards that are supported by this feature and their performance
specifications.

Virtual Ports

Virtual ports support hierarchical egress traffic shaping at more than one level on a single UNI port,
combining virtual path traffic shaping and associated virtual connections. This feature allows one or
more Virtual Ports per Physical Port interface.
A maximum of 31 virtual ports are available per BXM card. Each port supports all autoroute traffic
types currently supported by physical ports. Up to 255 virtual ports are supported per BPX node (with
BCC-4-128) and 144 ports (with BCC-3-64).
