Multiple subnets between cisco and HP

[BigJon_1]

We have an HP C7000 with 8 blades all configured for the subnet 172.30.210.0/24.

Right now the C7000 connected via its HP GBe2c switch to a Cisco 6509 and a single cable.

That port is a switchport accessing vlan 210 on the 6509.

I want to be able to configure addresses on the blades to different subnets, not just 210.

I have tried to trunk the port on the 6509 but havent been able to get it to work right.

On the Cisco side here is the interface details...

6509#sh int g9/47 trunk

Port          Mode         Encapsulation  Status        Native vlan
Gi9/47        on           802.1q         trunking      1

Port          Vlans allowed on trunk
Gi9/47        1,200,210

Port          Vlans allowed and active in management domain
Gi9/47        1,200,210

Port          Vlans in spanning tree forwarding state and not pruned
Gi9/47        1,200,210

On the HP GBE2c side I have the connected port 21 configured as vlan tagging enabled, pvid 1, vlan 200 and vlan 210 created, enabled and assigned to port 21 too.

I'm not sure if this will help, but on the 6120XG you do all the tagging configuration on the vlan itself.  For example, lets say you have vlans 1,200,210, and you want the servers in slots 1-3 to be a member of each vlan, respectively. On the 6120XG, the config would look like this:

interface 21

    name "Uplink to 6509"

exit

vlan 1

    name "PVID 1"

    untagged 1

    tagged 21

    exit

vlan 200

    name "VLAN 200"

    untagged 2

    tagged 21

    exit

vlan 210

    name "VLAN 210"

    untagged 3

    tagged 21 

    exit

 You might also have to look at Spanning tree because the HP and Cisco might not be playing nicely together
