Problem with dropped pings. Any thoughts?
server <--> core <--> switch1 <-->swich2
Pings are dropped when pinging from switch 2 to core and from switch2 to server.
Pings are fine from switch2 to switch1
Pings are dropped when pinging from core to switch2
Pings are fine from core to switch1
Etherchannel between switch1 & switch2
Etherchannel between core & switch1
fiber between core & switch1
fiber between switch1 & switch2
See Rec_Err incementing on one of the gig port from switch1 to switch2
How do I confirm that the fiber is good between switch1 & switch2?
I see Rev_Err incrementing on on of the port in switch1. I also see speed set to auto for switch1 and hard coded for the core on the connected ports of the Etherchannel.Could that be the problem?
Probably, what happens when you set boht sides to auto (also clear counters if you want reset counters)? If no good, then could you post the configs of all ihts and etherchannels on both sides?
It won't let me. I was trying to access the interface and set speed to 1000. But it speed rejected. Also, it only gives me the option nonegotiate. Not sure why? Is it because the interface belongs to a port-channel?
