We have bought an IBM BladeCenter H with 4 blades. Each blades has 2 NIC's and each NIC is connected to one of two Bladecenter compatible Nortel GB Switches.
Everything is working as long as we don't use VLAN's.
For our OOB network we've created a seperate portgroup (VLAN 101) and we want to connect this to an untagged VLAN net work of our external Dell PowerConnect 6248 switch.
On the 2 Nortel switches we also defined a VLAN 101 on all internal ports (tagged) and on 1 external ports (untagged) and have connected the external port to the vlan on a DELL PowerConnect 6248 (also untagged).
This is not working. We have a similar setup with a Dell PowerEdge 2950 (no blade) and that's working just fine.
I assume something is wrong in the intermediate Nortel switches (I don't have much experience with Nortel) since both the Dell Switch and the ESX are configured in the same way that the working setup is.
In attachment I have a few overviews of the setup.
What am I doing wrong?
