Assigning Descriptions to Virtual Paths
To assign a description to an individual VP on an ATM interface, use the atm
vp-description command. The VP description does not affect existing descriptions
configured for the ATM interface or ATM 1483 subinterface on which the VP resides.
However, if you delete the ATM interface, the descriptions of all VPs residing on that
interface are also deleted. In addition, if you decrease the VPI range by issuing the
atm vc-per-vp command, the router deletes the descriptions of any VPs that are
removed.
To display the VP description, use the show atm vp-description command, as
described in “Using ATM show Commands” on page 74. Although you need not
configure a VP tunnel to specify a VP description, the router also displays the VP
description in the output of the
show atm vp-tunnel command.
Exporting ATM 1483 Subinterface Descriptions
To assign a description to an ATM 1483 subinterface and configure the router to
send the ATM 1483 VC interface descriptions to the line module:
1.
Configure a text description for ATM 1483 subinterfaces with the atm atm1483
description command. This description is included in the interface identifier
that is sent to AAA.
To configure this feature for ATM 1483 subinterfaces, enter this command in
Profile Configuration mode. See “Configuring ATM 1483 Dynamic Subinterfaces”
on page 628 in “Configuring Dynamic Interfaces Using Bulk Configuration” on
page 623.
host1(config-subif)# atm atm1483 description VC_atm1
2.
Set up the router to export ATM 1483 VC interface descriptions to the line module.
host1(config)# atm atm1483 export-subinterface-description
3.
(Optional) Display the configuration of the export ATM 1483 VC interface
descriptions feature with the
show atm atm1483 command.
host1# show atm atm1483
ATM1483 IF Descriptions exported
4.
(Optional) Display the interface descriptions with the show atm subinterface
atm command.
