We have recently switched from HP Procurve series to HP Comware based switches. A configuration which has been working on Procurve doesn't seem to work on Comware. Here are the details:

The provider interface is Cisco based, network connectivity is delivered using a specific vlan (provider side), lets say vlan 600.

We have defined access ports on HP switches for internet access, using vlan 2. Port mode is access port. So I would expect the switch to discard the incoming vlan tag 600 and forward packets internally to all ports assigned to vlan 2. A 2nd access port on the switch with vlan 2 connects to the firewall wan port.

Configuration is as simple as it can get, first for HP Procurve, 2nd for Comware Switch:

Procurve:

vlan 2
   name "Wan"
   untagged 1-4
   tagged 15,43-44
   no ip address

Port 1 is connected to provider uplink, port 2 to Firewall WAN IF. WORKING!

Comware:

interface Ten-GigabitEthernet1/0/3
 port access vlan 2
interface Ten-GigabitEthernet1/0/4
 port access vlan 2

Port 3 is connected to provider uplink, port 4 to Firewall WAN IF. NOT working.

So where is the difference between Procurve and Comware Switch? Is there anything I'm missing? I would expect to see port 3 & 4 communicate, as they are forced to the same vlan 2. But I do only see a MAC address entry on port 3 (Firewall MAC), no MAC from provider uplink on port 4.
