We have 2 trunks on each of our core switches between 2 campus buildings. Trunk 1 uses ISL ports 6,7 on both switches, and Trunk 2 uses ISL ports 54,55 on both switches. Our switches are brocade 5300 model on 6.1.0c firmware. Anyhow - all the ISLs are health except for port 55 in our redundant data center. All settings are the same as the other 3 ISL connections - ie: ports configured the same way, same distance, same quality of fiber (comfirmed with FLUKE), same SFPs etc. For this 1 particular port, 1 side gets 0 ENC_OUT errors - very clean, but the other side has a large amounts of ENC_OUT errors building up (via porterrshow - few thousand every second).
Please advice. Thanks.
