and routers are ISP provider and i don't have any chance doing with them.
I don't know how much routers are on the way
In the one DC is 3750X stack on the other DC is 3750X stack between them is LACP protocol.But if the line is break on the way i don't shutdown on my cisco stack and i must wait 1,5minutes then LACP detect broke line and redirect traffic to the other line.
On the 3750X is impossible change LACP timeout.
I think that the solution is IP SLA and ICMP responder between mgmt ip adresss and shutdown interface.But the ICMP traffic go across one line based on hash.
Do you have Any idea?I know the solution is STP but it is the last chance
