Cisco Vlans and BL p-Class GbE2 Interconnect Switch

Hi There

I currently have a requirement to trunk VLANS between a Cisco 4006 switch and HP blades on a BL p-Class GbE2 switch. Unfortunately this is a production environment so I cannot replicate in a test environment. On reading the available documentation I am unclear on the following points..

In Deploying the ProLiant BL p-Class GbE2 Interconnect Switch into a Cisco-based Network
In all examples it states ..
"Any remaining Catalyst 6509 ports must be separate from VLANs 1 and 2 and are collectively represented in Figure 1 as VLAN 3
Note VLAN tagging (trunking) must be enabled on all ports within VLANs 1 and 2.

Does this mean that I have to have separate VLANS on the server blades than on the access ports on the cisco switches i.e i can configure blade servers into vlan3 but i cannot have access ports on the Cisco switch in VLAN 3. I have to have access ports on the Cisco switch in a different VLAN, VLAN 4 for example and L3 route the traffic on the Cisco switch between VLAN3(Server Blades) and VLAN 4(devices attached directly to access ports on the cisco switch)

And also .."and that the Cisco “native VLAN” matches the PVID assigned by the GbE2/GbE2c switch port. The Cisco native VLAN is the only VLAN assigned to the port(s) that sends frames untagged."

Can you clarify this??

Any help much appreciated.

Thanks

Hugh

Re: Cisco Vlans and BL p-Class GbE2 Interconnect Switch

Hi,

I've got the exact same problem.

My GbE2 switches are connected to a Cisco 3548, all VLANs work fine except the VLAN 3.

If replacing the Gbe2 with a Linux box I can access VLAN 3. (for testing purpose).


Any clue ?
