Hi all, hopefully someone can help with this. I have a couple of 7260s on 4.20.16M that no longer recognize the installed transceivers. Not sure what happened in one case (possibly reboot due to power outage), but the second one occurred on an upgrade to 126.96.36.199M. Reload the system, and all transceivers show ‘Not Present’. Returning the system to 4.20.16M had no impact, still no ports.
Each of these systems has 5-6 Arista QSFP-100G-SR4s installed, and were fully operating normally before whatever happened. I’m fairly new to Arista but don’t see anything unusual in logs. I made no changes to configs – although I do see channel 3 (sometimes 2, 3, and 4) for each interface. All ports are unchannelized 100G, and were reporting just ‘Et##/1’ for all interfaces until this incident.
Any suggestions would be appreciated. These are test boxes, so I can open a case it just isn’t a priority at the moment.
