Dell Powerconnect 6248 and Catalyst 3020 blade switch question
Hello all,
I have (2) Dell 6248's connected together with stacking modules that act as my "core" network switches. I also have (2) Cisco Catalyst 3020 blade switches that act as my "distribution" network switches; all of my blade servers are connected to these 2 catalyst switches. My Dell 6248's each have (4) 1000-BASESX LC connectors, and LC to LC fiber connecting to (4) 1Gbps BLP SFP's on my Catalyst 3020's.
I have (6) VLAN's on the 6248's that I'd like to add to a trunk, and present those VLAN's to the 3020's. I do not want any single point of failure in my network; if one of my 6248 or 3020 switches fail, I want my blade servers to always maintain network connectivity. I'm considering doing the following; any feedback or alternative ideas would be greately appreciated:
1) Configure the (4)1Gbps SFP fiber ports on each 6248 in an LACP etherchannel. Configure the (4) 1Gbps BLP SFP's on my Catalyst 3020's in an LACP etherchannel.
2) Assign my 6 VLAN's to the (4) ports on my 6248's.
3) Enable GVRP on both the 6248's and the 3020's.
Should flowcontrol on the 6248's be on or off? If a single port in my 4-port etherchannels fail (or a cable gets pulled), will the link stay up in a degraded state, or will the link go down? Is LACP the best option for link aggregation to guarantee if a single link fails, our servers will maintain connectivity to the core network?
Some additional background on this - this client has Dell 6248 switches throughout their environment, but is an HP blade server shop (hence the Cisco 3020 catalyst blade switches).
Feedback/comments would be appreciated.

Did you get the GVRP working on the PowerConnect 6248 switches?
If so, could you post the details of your config?
Thanks.
