Catalyst 6500 redundancy

Hello,

I would like to know witch kind of redundancy, dual msfc or single route mode, is the best election in terms of performance with these two scenarios:

1- Single 6500 chassis with two supervisor 1/PFC/MSFC2

2 - Single 6500 chassis with two supervisor 2/PFC2/MSFC2

Thankyou

Re: Catalyst 6500 redundancy

If you are looking to implement two chassis in the network with 2 supervisors/msfc then SRM is the best, like having two switches with failiver MSFC. You don't have to configure the second MSFC in the Chassis and , no need to worry about any RPF etc.. But if you have only one core, then ppl usually use the two MSFC and try to do load balancing using the HSRP across VLans plus the convergence time will be little bit faster than the SRM.

Hope this helps

Re: Catalyst 6500 redundancy

Yes, I am going to implement two chassis with two supervisor-1/msfc in the network. My doubt is about the performance obtained with one or two msfc active, because supervisor -1 needs the msfc to route the first packet of every flow (the load is divided /2). What do you think about this?

Another question is about convergence time with SRM or dual msfc. Is the HSRP convergence time, with default values, less than SRM or dual msfc convergence time?

Thankyou
