We have a small FMC with four Brocade 6210 switches. We don't normally login to these switches other than to update FOS... But we noticed that they were very slow to log into and to operate via SSH, and we could see that it was because of the snmpd deamon running... when we disabled it, everything was OK again... "snmpconfig --disable snmpv1" Only "thing" that is using theis is the ONTAP Cluster nodes.. (2 nodes).. but there is no way to configure any poll times.. ? Is this normal? (we are currently on 9.11, but upgrading this weekend)...
#ONTAP Storage Switch monitoring causes high CPU load on Brocade switches

Check the FOS release notes. There were known issues with the SNMP deamon leading to higher CPU utilization.
What FOS version are you on?

v8.2.3d

Those 6210 are slow as hell. Yes, there is an snmp issue, nevertheless the are just slow.... Aren't they EOLed already?

I think you mean Brocade 6510, right?
coral yoke
v8.2.3d
That's already the latest supported version. I would simply ignore this, if you don't see any performance issues on your FMC.
It's most likely this bug FOS-835586. They tried to fix this in the latest versions already but it's not a complete solution.
Check this KB: https://kb.netapp.com/onprem/ontap/metrocluster/High_CPU_observed_on_Brocade_switch
"Upgrade to a fixed release for Bug #1402830. This bug states "Cisco" in the title but the change applied here will improve the performance of querying a Brocade switch."
The bug is not public, so ask NetApp in which ONTAP release that's fixed.
Or simply ignore it, these switches are EOS 31-Aug-2024 anyways
