GS324TP — S350 loses connection with Ubiquiti Access Points
Model: GS324TP — S350 Firmware: 1.0.0.43 Boot Version: B1.0.0.5 Periodically, all the Ubiquiti Access Points lose connection to the switch. (Less frequently, but just as annoying: The Epigy p...
Consider to consult
Monitoring -> Memory logs
Are these Ubiquiti Access Points in some Mesh mode where STP loops would be predictable?
Apologies for the delayed responses. I will follow your suggestion for looking at the memory logs as soon as I'm able to get back to the church.
And now I will show my complete ignorance: Yes, Ubiquiti Access Points are in Mesh mode. But I don't know if/how STP loops could be predictable. Would appreciate any insights.
Some workarounds on the Ubiquity mesh APs we now we know NOT to enable Wireless Uplink unless we really need it, and make very sure to disable it before re-establishing the Wired Uplink.
In the Unifi ecosystem, all switches STP prio are set at 32768 and in MAC order if I have it right.
Once again, apologies for the delayed response!
Thanks for the suggestion to look at the Memory Log.
I found that our copier (Canon IR-ADV C5045) was causing flooding the logs with:
Main Switch-1 TRAPMGR[lldpTask]: traputil.c(795) 3110 %% NOTE LLDP-MED Topology Change Detected: ChassisIDSubtype: 5, ChassisID: 192.168.1.4, DeviceClass: 3, Interface: g19
Until I can get into the copier to check out it's set up, I disabled LLDP on port g19.
Additionally, I implemented a timer schedule to power off the power on the access points nightly.
Until I can get some help with figuring out our STP set up (I have someone volunteering to help me next week), this seems to have slowed the access point connection drops.
I'm also getting a large number of the following
<11> May 6 10:45:30 Main Switch-1 DOT1S[hapiRxTask]: dot1s_txrx.c(269) 1432 %% ERR dot1sBpduReceive(): Discarding the BPDU, since it is an invalid BPDU type
<13> May 6 10:45:30 Main Switch-1 DOT1S[hapiRxTask]: dot1s_txrx.c(1169) 1431 %% NOTE dot1sBpduReceive(): Invalid Hello TimeI can't tell what port this is coming from, but I'm assuming it's a) related to the STP set up not being ideal and b) probably coming from the Spectrum router. IS there a way to find out which port is causing this?
Thanks for your help so far!
Will post an update once I get the STP situation figured out.
