I have several question regarding a HP c7000 enclosure blade I/O module Brocade B-series 8/24c which should be interconnected with a CISCO MDS NX-OS fabric using access gateway mode.
As far as I know at this point, i can group several N-ports to a N-port group each group bundled with several initiators (blades). Those F-ports are distributed along the available N-ports in the group according to policy settings (but always via a fix mapping between F and N-port, therefore no load-balancing ...).
Now I also saw in the Access Gateway Admin Guide that AG also supports trunking.
What i want to do is, enhancing the bandwidth cause with normal AG NPIV, each host only has connection viua one of the definded N-ports of the N-port group.
So what i do not understand is (i dont know if this really is possible) how to bundle N-port to a trunk and to interconnect that one to a fabric.
What i saw in the docs is that AG trunking is not supported in M-EOS and third-party switches- does that mean i cannot establish a link between AG enclosure B-series module and a CISCO fabric?
So in case this would work- will the N-ports of a AG N-port group then be bundled to form a trunking link? I did not find any example for that.
So if anyone has a clue i would be thankful for support!!!

You cannot stablish a trunk between a Brocade AG and a Cisco switch. In order to set up a trunk like the one you mention, the AG and the switch must be Brocade working in native mode.

Ok- thats what i already thought.
But you say that AG and switch must be in native mode when you establish trunk between two Brocade devices- but native mode is fabric mode so AG is no AG anymore. But in AG administration guide there is stated that AG can run trunks.

I want just clarify somewhat, from my point of view are some post here a bit confused:
First at all, basically AG is a own Mode.
Second, If the switch is set in Native Mode, cannot be Interop-Mode 2-3
and finally, no matter if the switch is set as AG or Native, FOS 7.x ( if FOS 7.x is loaded ) not longer supported Interop-Mode.

Yes- thats clear.
Interop 2 and 3 are no longer supported by FOS 7.x and Interop 1 is gone since FOS 6.x.
Question was just if it is possible to aggregate N-port links to a CISCO fabric if Brocade is in AG mode.
But only way is now to lower the ratio from host/initiator to N-port/groups AG towards CISCO fabric.
