Switch Firmware Update 1.0.1 Build 20210407 Rel.64538 broke RSTP
Yesterday's (May 21 2021) firmware update for the SG2210MPs and SG2008P caused switches to start bouncing up and down.
Had to remove (disconnect) physical wires from ports that were redundant or loops. Double checked all ports that were switch to switch were still assigned a profile I had created called "switch interconnect" that had "enable loopback protection, run RSTP" as it's config.
Double checked each switch's main config area and both loopback and RSTP were all still enabled.
Also various other things broke such as in the Omada dashboard, click on network (to right of "overall") and "traffic activities" "switches" the graph just went to zero flatlined so something is going on with statistics gathering.
This is SG2210MP's (4 of them) with a SG2008P mixed in running off an OC200 with the latest firmware. OC200 plugged into one of the SG2210's PoE ports to power the OC200.
