SG350X-24MP Stack, Standby slow

[JohnD2]

We currently have 2 brand new switches in a stack. The master switch works great, but the standby switch is slow and particular devices like IP phones connected to it are nearly unusable. The phones lose connection to the server and freeze up. If the phones are connected to the master switch they work fine.

I've set up a separate stack and it does the same thing. I've changed which switch is the master and standby. Which ever switch is the standby in the stack just doesn't work well. This rules out faulty hardware to me. Nothing shows up in the logs on the switches. I'm unsure of what to do at this point. Maybe a QoS issue since it's only certain devices and processes that are slowed down?

I followed these instructions to configure the stack: link

Anyone got any ideas?

they genereally use smartport config default,

can you post show run to look.

[JohnD2]

Sorry for the slow response. It does appear that smartport is on.

This is a port with an IP phone plugged in, and it looks like smartport has recognized it as such.

remove the macro lines and test it

[JohnD2]

I disabled the auto smartport and it works now. I'll take some time to do more testing, but I think I'm finally making some progress. Thank you!

Glad to know it is working as expected.
