Not Working: Cascade two AG (Brocade 300 - Brocade 200 AG - HP 4/12 AG)

Hello,

 

I'm trying to cascade two access gateways as per published Brocade AG documentaiton and running into an issue.

 

We have:

 

- Brocade 300 in Native Mode running FabricOS 7.1.1

- Brocade 200 in Access Gateway Mode running Fabric OS 6.2.2f

- HP 4/12 Blade Interconnect (C7000) in Access Gateway Mode running Fabric OS 6.2.2f

 

What I'm trying to do is:

 

[Brocade 300 - NATIVE]  ---  [Brocade 200 - AG (Core)]  --  [HP 4/12 AG (Edge)]

 

In the above configration both:

 

- Brocade 200 uplinks to 300 via 2 x 4G links

- HP 4/12 uplinks to Brocade 200 via 2 x 4G links

 

- Brocade 200 and HP 4/12 switches were configured as follows:

switchdisable

ag --modeenable

(reboot)

ag --policydisable pg

ag --policyenable auto

switchenable

 

No other commands were used.

 

I see uplink ports from HP 4/12 negotiate as G ports on B200.   One of the two uplinks disables.

 

What works:

 

- When I connect both Brocade 200 AG and HP 4/12 AG to B300 directly (no AG cascade).

 

Question:

 

- Is my target state supported?

- Am I missing a command / setting / parameter somewhere?
