High error rate on PortChannel

[niki1365]

Hi

I have one Nexus 5696q and some 3850 & 2960 switches. 3850(2960x) Switches connect to Nexus 5k via Fiber Cables. When i Configure Ether Channel between Nexus 5k and any of 3850 Switches i get "High error rate" error on port channels in Nexus 5k and 3850(2960x) Switches. on ethernet ports that not bundled into port channels i never get "High error rate". What's your idea?

Best Regards

Hi,

What protocol do you use for the Portchannel?

I use LACP in active/active mode for EtherChannel.

my idead would be;
try ocnfigure mode on - on both sides. also check the load balance on both sides. clear the counter errors and watch if increments again.
sh int counters errors
SW-ATH-FL-1-1#show etherchannel load-balance
EtherChannel Load-Balancing Configuration:
src-mac

EtherChannel Load-Balancing Addresses Used Per-Protocol:
Non-IP: Source MAC address
IPv4: Source MAC address
IPv6: Source MAC address
