x25 htc




x25 htc circuit-number

Syntax Description:

VC number from 1 to 4095, or 0 if there is no two-way VC range.

Command Description:

To set the highest two-way virtual circuit (VC) number, use the x25 htc interface configuration command.

Usage Guidelines

When X.25 calls are placed across the interface between an X.25 DTE and the X.25 network, virtual circuits (VC) are established to carry the data associated with the calls. These VCs fall into the following categories: Permanent Virtual Circuits (PVCs), incoming-only, two-way, and outgoing-only. All VCs are numbered, and each of these categories occupies a consecutive range. All PVCs must be numerically lower than all incoming-only VCs, which in turn must be lower than all two-way VCs, which in turn must be lower than all outgoing-only VCs.


The following example sets a valid two-way VC range of 5 to 25:

Router(config)#interface serial 0/0
 Router(config-if)#x25 ltc 5
 Router(config-if)#x25 htc 25
