Issues with scheduled firmware updates and BGP

[calebvorwerk]

I have upgraded(scheduled through netonix manager) a couple netonix's on our network to 1.5.19 and then one to 1.5.21. Both times, I woke up to that Netonix being down. We have BGB running between a couple towers. The towers backhauls are powered by the netonix, and the mikrotik router plugged into the netonix. After the update, our mikrotiks bgp would not come back up. I had to downgrade the netonix to fix the problem, any ideas what might be going on here?

Seems almost like we lost VLAN functionality after the update

I would NOT do scheduled upgrades until after you are up to v1.5.22

My guess is this an SFP module did not come up and either needs a cold boot or pull insert.

Replace the SFP modules if this is the case.

In the main thread for v1.5.22 I discussed several times no how to test your SFP modules.

Also if these units were up for a long time v1.5.19 still had memory leak especially with SNMP and the more often you probe the unit the more memory grows. SNMP should not poll the units faster than 1 once per minute and that is really more than reasonable. These switches have very small CPUs. The CPU has nothing to do with

IF a unit is up a long time check memory, if high reboot first but if you have an SFP that does not like the older software which we fixed 99% of SFP modules in v1.5.22 then also either do on site or be ready to roll if needed.

Read on how to check your SFP modules in other thread.
