Have a few different buildings running B5G124 switches (Fw 06.81.04.0001) with Fiber uplinks to our core. For the past few months been receiving intermittent high ping response (100-300 ms) with no packet loss. Clients are now intermittently experiencing delays of data up to approx 20 seconds every few hours. Noticed a high TX Pause Count on the B5 switches Fiber uplink. Noticed an Extreme article which spoke about disabling flow control on these uplink ports with high TX pause count. Wondering if this is a good idea or any other suggestions to evaluate?
