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)
