We have two switches, at one side Nexus 7010 & other side cisco 2960. having 2 fiber link in between them. both switches are far from each other.
one fiber link is direct dark fiber other is provided by ISP so mux would be in between.
My question is 1) can I make etherchannel / port channel for two interface ; will I work??
2) does fail over will work within etherchannel; how switch will come to know port is down; will physical l2 interface goes down if link gets down in between specially mux is in between them??
3) if I don't go for etherchannel, then spanning tree will block one port.. but if link is down in between switch port will not receive bpdu so failover can be done. is it?? or port need to get down physically ?
