Can Huawei S12700 with VBST receice BPDU with topology-change flag from Cisco PVST?


Huawei S12700------cisco 3750
   VBST              PVST            

When disconnect and connect computer on port GigabitEthernet1/0/13
BPDU with topology-change flag is sent from 3750 to S12700,
but on S12700 i can see no new opology-change:

display stp  vlan 2 topology-change
VLAN 2 topology change information
   Number of topology changes             :20
   Topology change initiator(detected)    :GigabitEthernet5/0/16
   Time since last topology change        :1 days 18h:26m:44s   (OLD)

I suggest you refer to the product document. There're some interconnection examples.

As I know, Huawei VBST is compatible with Cisco PVST.

Can you show the STP state on CISCO 3750.

Usually, the state change of edged-port would not trigger STP change by using portfast function, so we have to check whether the STP topology changed or not on CISCO 3750.
