Description Use the atm-link check command to have the protocol state of the ATM P2P sub-interface change depending on whether the physical interface is up and whether a PVC is configured on the sub-interface. The protocol of the sub-interface, which comes down otherwise, goes up when the physical interface is up and a PVC is configured on the sub-interface.

Use the undo atm-link check command to restore the default.

By default, the protocol of the ATM P2P sub-interface goes up or comes down depending on whether the physical interface is up or down.

This command applies only to ATM P2P sub-interfaces.

Example # Enable the protocol state of ATM P2P sub-interface 4/0.1 to change depending on whether the physical interface is up and whether a PVC is configured on the sub-interface.
