Configuring the Interface Link Distance

Specifying the physical link distance for the next ATM hop in the outbound direction allows you to
increase the propagation delay. Propagation delay is used in determining the connection admission
control (CAC) maximum cell transfer delay (CTD) provided on the output by a switch interface, which
can affect the switched virtual channel (SVC) connection requests accepted.
For a detailed description of the CAC algorithm pseudo-code on the ATM switch router, refer to the
Note
Guide to ATM Technology.
To configure the interface link distance, perform the following tasks, beginning in global configuration
mode:
Command
Step 1 Switch(config)# interface atm
card/subcard/port[.vpt#]
Switch(config-if)#
Step 2
Switch(config-if)# atm link-distance kilometers
The atm link-distance command affects subsequent connections but not connections that are already
Note
established.
Example
The following example shows how to configure the outbound link distance to 150 kilometers:
Switch(config-if)# atm link-distance 150
