CCA Erro log : Unexpected BPDU received. Port has been Disabled

[nicanor00]

I have a problem with the Catalyst Express 500 24 port switch. I use CCA to configure this switch.

For some reason I get random reports in Cisco Network Assistant indicating the following:

"Unexpected BPDU received. On 1 port, Port has been Disabled"

The only thing I do to get them back online is to reset physically reset the switch or manually disable the port and then manually enable the port.  I'm baffled as to what can be causing this.  Have any of you seen this type of problem before.

Thanks,

Hi,

The error message points that the interface on this switch received spanning tree BPDU which is not expected. This can happen if you have enabled port security or spanning tree feature like bpduguard on the interface.

Please let me know if the affected ports are access ports or trunks? Also mention what is connected to the other side of these affected interfaces.

Cheers,

Shashank

Let me explain the architecture

I have 2 site connected with point to point radio link

A wireless equipment(point to point radio) is connected on this port site A, and on the other site B I connected another Catalyst Express 500 24 port(without poe port)

When power go down on site B, the port(where the radio are connected) on site A is disabled, when the power come back the port remain disabled

I configured trought the CCA the access port vlan 100 and voice vlan 200

How can I disabled the port security or spanning tree

what can be the inconvenient if I disabled this 2 features ?

How can I solve this problem

I dont whant this port to be disabled again if the power go off the site B
