VIPRION Network Failover

I'm about to add an additional blade to each of my VIPRION C2400 chassis, and I'm looking for any information/documentation on how to handle network failover with chassis that contain more than one blade. I can't find any solid documentation on this anywhere (perhaps I'm looking in the wrong place). I also have a support case open, but haven't gotten a straight answer yet.

 

 

Currently, I have two chassis with one blade each. Network failover is made possible by a directly connecting 1/1.8 on each blade in each chassis to one another. I am currently using a unicast network failover address.

 

 

 

When adding additional blades, I am guessing that instead of cabling blades directly to each other, I should cable them all to a switch and place them on a common, isolated L2 VLAN; which would be used for network failover and configsync. Does this make sense?

 

 

 

Also, should I switch from a unicast network failover configuration to a multicast one? Support mentioned that I need to configure trunks per SOL13754, but I'm not sure if this means that I need to create one or two trunks (one per chassis)?

 

 

 

Any advice would be much appreciated.

 

 

 

Thanks.
