Tag Switch Controller: For a tag switch controller, the delshelf command is also used to deactivate
the link between the BPX routing node and the tag switch controller. In the case of tag switching,
this is a link between a port on the BXM card and the tag switch controller. This link can be
connected to a port that has been upped by either the upport or uptrk command, as the tag switching
operation does not differentiate between these modes on the BXM.
Virtual Trunks: If you include the optional vtrk parameter, uptrk activates the trunk as a virtual
trunk. If the front card is a BXM (in a BPX switch), uptrk indicates to the BXM that it is supporting
a trunk rather than a UNI port. (See the upln description for the BXM in port mode.)
You cannot mix physical and virtual trunk specifications. For example, after you up a trunk as a
standard trunk, you cannot add it as a virtual trunk when you execute addtrk. Furthermore, if you
want to change trunk types between standard and virtual, you must first down the trunk with dntrk
then up it as the new trunk type.
You cannot up a trunk if the required card is not available. Furthermore, if a trunk is executing
self-test, a “card in test” message may appear on-screen. If this message appears, re-enter uptrk.
Example 1
Activate (up) trunk 21—a single-port card, in this case, so only the slot is necessary.
uptrk 21
Example 2
This example shows the screen when BXM trunk 4.1 connected to a Tag Switch Controller is upped
with the following command:
uptrk 4.1
