[mobility master] What networks should it be connected to

Hi,

We are currently working on adding a Virtual Mobility Master to our setup (single 7030 controller, switching to virtual mobility master with backup and 2 7030 controllers).

The VMM comes with 3 NICs, we have multiple VLANs in use for our different wireless networks and VMware has only "trunk of all vlans" or single networks that can be connected to a NIC.

 

So I have a two fold question:

1. What network do I truly need to exist at the VMM level? The wireless VLANs are important for the controller but it seems to me that other then knowledge of them the Mobility Master does not actually need a leg on them.

2. Will the VMM blow up if I add more NICs if I do need more then 3 different VLANs there? I really don't like the idea of having a trunk with all networks available on the vSwitch go to the host.

 

Thanks!

 

Technical details:

Controllers - 7030

AOS - 8.6 or 8.7 [I'm doing the new setup with 8.7, currently running 8.6.0.5, any red flags with 8.7?]

The VMM doing only control-plane , So you need to make the vm be able to connect your MDs ( controllers ) other vlans arent needed.

 

You can use just one NIC .. as basic trunk or with a basic access "Mangment VLAN with the ability to establish connectivity to your controllers.

 

 

Use 8.6.0.5 or 8.5.0.10

The wireless VLANs do not need to be present on the MM at the switch level. Most cases it is just the management VLAN of the MM.

 

2. Will the VMM blow up if I add more NICs if I do need more then 3 different VLANs there? I really don't like the idea of having a trunk with all networks available on the vSwitch go to the host.

 

I've never seen this before, I'm curious what is your requirement for having multiple interfaces on the MM?

Hi Craig - Adding more NICs would have been useful had the answer to question 1 been "yes you do have to have all these vlans connected to the mobility master", in that case adding a NIC for each vlan would solve the problem of not trunking all the vlans available to the VMware host to the mobility master.
