M1000e Networking Help
Hey All,
Just wondering how the NICS in a M710 are assigned to the internal switch? as the switches have 16 internal ports and 4 external. Is nic 1 of every blade hard wired to nic1 on the internal switch and nic2 to the 2nd nic on the internal switch? Any help would be greatly appricated.
I currently have 4 M6220 Stacked with a dual port nic expansion card in some M710 blades. I know that the first 4 onboard nics in each blade map to the switches in A1 and A2 Fabrics. Then the last 2 nics are mapped to the B1 and B2 in each blade to the B1 and B2 fabrics. However I would like to split off the some of the connections to an isolated network for iSCSI, however I don't know which internal nics the blades are assigned to so I can't port aggrogate the proper nics to the external ports for seperation.
If anyone could give me a better insight on this, this would be greatly appricated.

The M710 should have 4 onboard NICs. 2 go to A1 and 2 go to B1. The blade then has 4 expansion card slots. Each expansion card would have 1 link to A2 or A3 and the other link to B2 or B3 (depends which slot on the blade you put it in). The expansion card you put in obviously would have to match the option type you put in the back of the blade center for connectivity (i.e. putting a fiber channel card in the blade to connect to A2 and B2, but then putting ethernet switches or passthroughs in those slots won't work).

Thanks for the post,
The mapping of the expansion cards to the Fabric slots I got down. The problem i'm currently having is mapping the internal switch ports to the external ports with the Group aggrigator. I have now know with the M710's the internal mappings work like this:
Blade slot 1
- First OnBoard NIC = A1 fabric (M6220 Switch1) Internal switch port 1
- Second OnBoard NIC = A2 Fabric (M6220 Switch2) Internal switch port 1
- Third OnBoard NIC = A1 fabric (M6220 Switch1) Internal switch port 9
- Forth OnBoard NIC = A2 Fabric (M6220 Switch2) Internal switch port 9
- Fifth Expansion NIC = B1 (M6220 Switch1) - Internal switch port 1
- Sixth Expansion NIC =B2 (M6220 Switch2) - Internal switch port 2
The problem i'm currently having now is mapping the internal ports to the external ports (17,18,19,20) As I want to split the traffic up into two different VLANS. However I guess this would now fall under the powerconnect forms section possibly? What I would like to do is have the 3rd Onboard nic(Internal port 9 A1) and the 5th NIC (Internal port 1 B1) on each blade be on a different VLAN going out a seperate External port (20) for iSCSI purposes, however I'm still running into any snags. The purpose of this is so if any one NIC controller is to go offline I still have a funtioning nic in a the teams I will setup. Reducing the single point of failure. If anyone has any additional assistance on this topic it would be greatly appricated !
