Fail UpLink Cisco WS-CBS3020-HPQ vs HP A7510

[roberto_paiva]

I configured one port in HP A 7510  with cisco  WS-CBS3020-HPQ and Cisco Switch gave me this mensage error:

*Aug 10 23:51:59.801: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/24, changed state to down
*Aug 10 23:52:00.808: %LINK-3-UPDOWN: Interface GigabitEthernet0/24, changed state to down

But when i Put one HP Comware 5900, the uplink is UP.

In the HP Comware 7510 have a this line comand in interface  but the link is down

 interface GigabitEthernet x/x/x/x
 port link-mode bridge
 duplex full

In the Switch Comware 5900 have this comand but the uplink is up

interface GigabitEthernetx/x/x
 port link-mode bridge
 duplex full

Thank you.

So what is the Cisco switch config on Interface GigabitEthernet0/24?

[roberto_paiva]

We created a contour solution and want to know if that is supported and/or recommended solution:

We put a H3C 5120 between the C3020 and IRF of 7510 (as in IRF 7510 <--> 5120 <--> C3020) so we can manipulate/test different settings with lower risk to the CORE of network (the 7510 IRF).

After execute a debug on interface connected to the C3020 we found that was being sent BPDU to STP mac-address 01-80-c2-00-00-00, even with interface configured with “stp disable”, then we considered that isn’t a MSTP/STP package but a PVST package as there is a few Cisco switches connected to the 7510 IRF.

As we know, the H3C/Comware cannot filter out PVST packages and as we need to keep the VLAN 1 active, we cannot just remove the VLAN 1 from trunk we configured as below follow:

On 5120 enabled at global level the "bdpu-tunnel tunnel-dmac" and on interface connected to C3020 we configured the "bpdu-tunnel dot1q pvst" then the C3020 maintained the connection up without showing any error and/or put the interface down.

So there is other way to “filter out” PVST packages on an interface other than remove VLAN 1 or use the bpdu-tunnel ? There is any caveat of use the bpdu-tunnel to get this “effect” (result?) ?

After the port is UP was removed the comand "bdpu-tunnel tunnel-dmac", and the port still alive.
