Hello,
I have two EX4200 fiber blades setup in a virtual chassis acting as my network core. Currently I am using Link Aggregation with LACP over two fiber ports to several HP Procurve switches throughout the building as a make shift redundancy. The second fiber blade is new and I now plan to move the second fiber port to the new blade. If one fails the other just takes over and everything is great.
I also will be plugging in a Cisco 5508 wireless lan controller which may some issues with that. The Cisco docs and forum clearly warn against spreading the lag across multiple blades, not clear about a virtual chassis though. Not a big deal as we have two controllers, so one per blade.
My question then, should I use link aggregation with lacp for the redundancy or should I just use spanning-tree? I want the lowest outage time possible so using a more talkative protocol is not a concern at this time. Thoughts?
Thanks,
Todd
