Hello I have a issue with spantree. This message appears

This occurs when I connect a Cat6500>SwitchAvaya>CatExpress 500.
Here are configured.
description "Hacia SW "
switchport access vlan 7
switchport mode access
no ip address
no cdp enable
You can see attachment.
I need to knows what do I can configured to this work well?.
Can you help me?.
Solved! Go to Solution.
The errors that you are seeing is because you have an access port connected to a switch that is probably a trunk and sending BPDU's. You should configure Gi1/1 as an 802.1q trunk. Since you have global BPDU guard enabled it puts the port into err-disable.
switchport mode trunk
switchport trunk encapsulation dot1q
Thanks for reply but I can not change it already that this access port is neccesary for that this connected to switch X without vlan or vlan1 for default so that catexpress is conneceted to switch.
that is to say.
6500 access port-- switch X(all port Vlan 1)--- CatExpress 500 (all port vlan 1) .
any change I need to do over the switch catalyst express 500. can you tell me how can I to do it?
You can also disable the global BPDU guard and enable it on the necessary interfaces.
no spanning-tree portfast bpduguard default
On the interfaces
spanning-tree portfast bpduguard
In my case I need this command be over interface can I type spanning-tree portfast bpduguard into interface gi 1/1 to do disable the BPDU?
and I have other question can I to use bpdufilter and what is command correct into interface.
or you can temporarily diable bpduguard and loopguard globally and enable again after you connect your switch. The problem is when you enable bpduguard globally, it is enable on all your access ports when you connect a switch to an access port, bpduguard will error disable that port when any BPDU's is detected on that port.
also remove any bpduguard or loopguard commands from your gig1/1 interface. if you are using access port in a specific vlan, then only that vlan is allowed between your switches unless you enable a trunk.
