Configuring Connections

ATM Configuration

SmartSwitch chassis, use this field to enter the interface number for which 
you wish to configure a new circuit. (Remember, each pair of redundant 
interfaces shares a single IF index.)

3.

In the VPI text box, enter the Virtual Path Identifier you wish to assign to this 
connection. Allowable values are 0 to 3; remember, the VPI you assign will be 
used to group virtual connections, allowing for channel trunking between ATM 
switches.

4.

In the VCI text box, enter the Virtual Channel Identifier you wish to assign to 
this connection. Allowable values are 0 to 1023

 for each VPI. For example, 

you could assign the same channel identifier — say, 25 — as many as four 
times: once with a VPI of 0, once with a VPI of 1, and so on. Again, remember 
that it is the combination of VPI and VCI that will be used to direct cells 
through the intermediate switches between the source and destination.

5.

Click 

 to add the new permanent circuit to the ATM interface. This 

circuit will remain in place until it is manually removed using the 

 

option in the Current Connections window.
