we are occuring and problem when connecting an two existing toplogy based on Catalyst Cisco 2960 & 2950 and existing toplogie base on 3Com Switch 8810 Core switch that we need to connect them to gather.
When connect the 3com segment trought an access port on Vlan 10 to to Cisco catalyst on defaut Port Vlan 1 on catalyst 2960. The catalyst seen on error message :
%SPANTREE-2-RECV_1Q_NON_TRUNK: Received IEEE 802.1Q BPDU on non trunk FastEthernet0/1 on vlan 1. %SPANTREE-2-BLOCK_PORT_TYPE: Blocking FastEthernet0/1 on vlan 1. Inconsistent port type.
After getting this error catalyst port used for this connexion stay in yellow color with non trafic passing.
Assuming that the catalyst switch port has a default configuration and there is another local Vlan used by another Catalyst port suching that Catalyst run PVST version.
when we connect to 3com switch to an access port vlan 10. and this switch run MSTP version, this configuration can cause this problem?
Please, what can you propose to resolve this issue?
PVST will block the port due to the BPDUguard being enabled. This the security part of PVST
Next, if on the Cisco port, which connects to 3COM, you have VLAN 1 and this is the native vlan, and on the 3COM you have VLAN 10, this will work, BUT somewhere on the Cisco you still need to define VLAN 10 for the communication with the L3 IP address.
In this case, if you really want there on Cisco access port I would suggest the following, even this is not best practice.
-disable bpduguard on the access port connection to 3com
-configure vlan 10, on both ports (cisco and 3com)
Then you have reachability inside VLAN and don't have to worry about STP.
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
