can ICX 7750 do MCT and stacking simultanously ?

can ICX 7750 do MCT and stacking simultanously ?

 

From the documentation , this is slighty confusing. In in sentence, it say it one or the other :

the Brocade ICX 7750 supports 12-unit distributed-chassis stacking or Multi-Chassis Trunking (MCT)

 

and then later on, it says it can do both

Brocade Multi-Chassis Trunking (MCT) supports dual homing of wiring closet access switches, or servers in a rack, to two Brocade ICX 7750 stacks in an MCT peer group, eliminating the risk of a single

 

Even on page 5 of the document brocade-icx-7750-ds.pdf the datacenter is on MCT stacks...

 

in our lab we get this error with version 8.0.30b : stack can not be enabled when MCT is enabled

Yes, that's right. We recommend VRRP-E for redundancy mechanisms between the stacks.
