Chapter 25 Configuring BXM Virtual Trunks
• virtual ports
You up and configure virtual trunks with the existing commands. The commands have additional
parameters for virtual trunk specific items. You up a trunk with
the trunk VPI (VPI range 1–4095) and other parameters on the trunk with
commands.
Below lists the permutation of virtual trunks that you can interface through the public ATM cloud.

The Ports and Trunks feature lets you configure multiple trunk lines and circuit lines on a single BXM
or UXM card simultaneously. In releases previous to Release 9.2, when you upped a single port as a
trunk (by using the
Similarly, when you up a single port as a circuit line (by using the
ports on the card are treated as circuit-line ports.
The Ports and Trunks feature is supported on the BXM and UXM cards for the BPX and IGX platforms.
A port, routing trunk and feeder trunk interface can be supported on a given slot containing a BXM or
UXM card type simultaneously. For example, a user of a BXM slot can have port 1 upped as a trunk
interface while having port 2 upped as a line interface.
For example a BXM card can have:
port 1 upped as a physical trunk
•
• port 2 upped as a feeder trunk
• port 3 upped with multiple virtual trunks
• port 4 upped as a UNI interface
Table 25-13 lists the interface types which can be supported on a single card.
