I’m a new user of the network devices omniswitch alcatel.
I’m trying to configure the loopback-detection on a alcatel 6860N. I’ve configured the trasmission timer at the value of 5 sec.The problem is that (in my test lab) when I create a loop between two ports ,the interfaces goes in a shutdown state after a variabile time between 5 and 120 sec. It’s a correct behavior? 120 sec is a lot of time when a broadcast storm is coming….
stp is disabled on the switch and this is why I use loop detection to avoid broadcast storm due a clumsy users...
Normal behavior is that the switch periodically sends out LBD frame from loopback detection enabled port as per the transmission timer (which is by default 30 seconds) and concludes that the port is looped back if it receives the frame on any of the loop-back detection enabled ports.
