Hello,
The 10Gb/stacking ports flapping in 22.5 on the x460G2 is a known issue that will be fixed under xos0073360.
In the meantime i suggest, like already mentioned before, to configure 150ms debounce timers on the stacking-ports as explained in the following article: https://gtacknowledge.extremenetworks.com/articles/Solution/Link-flaps-continuously-on-X460-G2
The implications of setting this 150ms debounce timer are that in case of a valid link down event of these ports, the switch will wait 150ms before it declares the link to really be down, so this could cause additional latency/delay in case of a real failover.
best regards,
Chris
