We have some Adtrans 908es 2nd gens out there that have issues with track and ICMP probe pings, and our issue is that when the primary internet goes offline, the adtran will send activate the backup connection but for less than a minute and go back to primary and keep the adtran offline until you physically remove the ethernet 0/1 wire, then the backup will kick in.
We are having major issues with certain firmware's up to AOS 13.10.1 and I believe now 13.11 as well.
Below is a sample of one of our failover scripts.
Let me know i you have a working one, or see what's wrong with ours here below. Thanks
