Hi,
We are trying to interconnect Cisco and HPE Comware switches with private vlan definition on HPE side. Cisco is detecting inconsistent PVID on the primary promiscuous trunk VLAN.
HPE Config
#
interface Bridge-Aggregation1
description ***-1:1/17***
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 270 2180 2184 to 2196 2198 to 2199 2203 to 2205
port trunk pvid vlan 1000
port private-vlan 2180 trunk promiscuous
link-aggregation mode dynamic
#
Cisco Config
interface Port-channel26
description
switchport trunk native vlan 1000
switchport trunk allowed vlan 270,2180
switchport mode trunk
!
Result
show spanning-tree interface te1/0/17
Vlan Role Sts Cost Prio.Nbr Type
------------------- ---- --- --------- -------- --------------------------------
VLAN0270 Desg FWD 20000 128.2306 P2p
VLAN2180 Desg BKN*20000 128.2306 P2p *PVID_Inc
Filtering BPDUs on Cisco side resolves the inconsistency and traffic flows normaly.
Both devices configured with pvst. Topology is converged.
Cisco
spanning-tree mode rapid-pvst
HPE
stp mode pvst
STP info on HPE side looks correct, at least for the 2 VLANs we are allowing in the Cisco trunk

Why is Cisco detecting PVID as 2180?
It is being correctly sent with TAG because otherwise it would not work with bpdus filtered, right?
Thank you
Best regards
