Functional Notes

This command enables the detection of a loopback alarm. This alarm works in conjunction with the sa4tx-bitcommand setting. The loopback condition is detected by comparing the transmitted sa4tx-bitvalue to the received sa4 bit value. If the bits match, a loopback is assumed. This detection method only works with a network in which the far end is transmitting the opposite value for Sa4.

Usage Examples

The following example enables detection of a loop alarm on the E1 interface:

(config)#config e1 1/1 (config-e1 1/1)#loop-alarm-detect
