Been using c6k for the last 8 years. started as the One True Core, but have migrated L3 DC core off to arista and now the c6ks mostly run the WAN (multiple 10G site to site) and what we'll call all the oddball stuff.
- Light MPLS/pseudowire (think of it as throwing really long cables between ports at different sites - I don't lean on it but it's handy from time to time for screwy stuff)
- really significant use of multicast/MVPN (5-10G/sec, maybe 300 groups)
- light NAT
- netflow
- handful of VRFs
Really, you could say I've been using the 6500s as fast-but-feature-light routers. Never broke 'em because I don't have a huge network. Haven't upgraded because, ain't broke yet / other things to do, and somehow 6800 was just never that compelling really.
Looked at c9k a year or two ago and was told "not well-baked-enough yet, run away".
Would like to use something like a 9500-48Y4C as a quasi-"drop-in-replacement" for the 6500s. (Don't have really high port counts on the 6500s, so this works.) Are these features likely to work well enough at this point, given I'm unlikely to stress-test any given feature that hard?
Can you use SWV to chain together a 32C with a 48YC or do the two switches have to be the same model? (understood that they might want to both be UADP3 or UADP2)
Can you use the ports on a 9500-32C or QC as 10G ports with the 10G-as-QSFP adapter thingies I've seen or does that not work?
