I have the following configured on a port in a switch A.
no ip address
spanning-tree bpduguard enable
When I plug in another switch, it always comes up with
%SPANTREE-SP-2-BLOCK_BPDUGUARD: Received BPDU on port FastEthernetx/x with BPDU Guard enabled. Disabling port.
%PM-SP-4-ERR_DISABLE: bpduguard error detected on Fax/x, putting Fax/x in err-disable state
On the switch B where it was plug into originally there was no spanning-tree bpduguard enable and it worked
So should I disable this command on Switch A, what will be the impact? or should I disable spanning tree on the new switch I am adding, what problems will it cause. I need to connect this new switch to Switch A.
Yes, disable the bpduguard. It is intended to ensure that nobody can connect an illicit switch to the port, and it seems to be working well! If you intend to connect a switch, then disable the feature.
Do not disable the Spanning-Tree, and do not put any bdpufilter. That would be bad news.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
