What do you have connected to all the ports that are having this behavior?
If they are clients then you can look at setting portfast on the interfaces. This essentially turns off Spanning Tree on that interface.
console(config)# interface gi1/0/1
console(config-if)# spanning-tree portfast

Hi, all these ports are connected to desktops and all are set as port fast in the STP Port Settings.
Please, any ideia why it's happening?

Hi PROCOPIO,
Did you get any reply or a solution to this?
I'm seeing this on quite a few of my Dell switches (6248P) and frequent disconnections on the uplink ports that are showing similar messages...
Again to confirm,,,,all edge ports are configured for portfast

Here are the options for spanning tree on a single interface.
62xx-Stack (config-if-1/g10)#spanning-tree ?
auto-portfast Allow to move to the forwarding state when BPDU
timeout occurs
cost Change an interface's spanning tree path cost.
disable Disable spanning-tree on an interface.
guard Configure a guard for the port.
mst Configure a multiple spanning tree instance.
port-priority Change an interface's spanning tree priority (in
steps of 16)
portfast Allow to move directly to the forwarding state when
linkup occurs
tcnguard Configure a port for tcn guard.

Whats the command to disable STP on individual ports ? and did you have frequent uplink disconnections before that or jus tthe logs throwing messages?
thnx

Hi Suman,
I just disabled STP on all desktop ports, this fixed the problem.
Cheers,
