Parameters-uptrk

Parameter	Description
slot.port	Specifies the slot and port of the trunk to activate. If the card has only one port, the
	port parameter is not necessary. An NTM, for example, has one port.

Optional Parameters-uptrk

Parameter	Description
vtrk	Specifies the virtual trunk number. The maximum on a node is 32. The maximum
	on a T3 or E3 line is 32. The maximum for user traffic on an OC3/STM1 trunk is 11
	(so more than one OC3/STM1 may be necessary).

Description

After you have upped the trunk but not yet added it, the trunk carries line signaling but does not yet carry live traffic. The node verifies that the trunk is operating properly. When the trunk is verified to be correct, the trunk alarm status goes to clear. The trunk is then ready to go into service, and can be added to the network.

If you need to take an active trunk between nodes out of service, the dntrk command may be used. However, this will result in temporary disruptions in service as connections are rerouted. The dntrk command causes the node to reroute any existing traffic if sufficient bandwidth is available.

Interface Shelves and Tag Switch Controllers: For interface shelves or tag switch controllers connected to a node, connections from those devices will also be disrupted when the links to them are deleted. For an interface shelf, the delshelf command is used to deactivate the trunk between the IGX or BPX routing node and the shelf.
