Now that you mention the "N-word" I have to ask (as we're looking into a
deployment)... how much of it is ready for prime time, and feature
compatible with the Catalysts?
One thing that is not there yet is EoMPLS support. You can pass LDP
through the box, but you can't land tunnels yet. That's supposed to be in
NOS 6.2, which I've been told several times will be released by the end of
this quarter (read: Friday...).
Under the hood, NX-OS is Linux, and the OS is modular, and features can be
enabled/disabled, based on the licenses you purchased.
There are a number of IOS <-> NX-OS quirks in the command-line, like
commands that have syntax that's just different enough to be kind of
frustrating when troubleshooting an issue at 2 AM :I
Another gotcha is the difference(s) between M1 and M2 series linecards.
You can't build a port-channel across M1 and M2 linecards, and M1
linecards have limitations such as bandwidth constraints to each ASIC
group (normally 4 ports). There are cases where you could need to change
one of the ports in the ASIC group to full-rate mode, which shuts down the
other 3 ports in the group... I haven't had a chance to test if there are
gotchas when running things like SPAN ports.
We've migrated one site from a Cat6509E to a Nexus 7009, and a few
transitional bumps aside, that went pretty smoothly. IPv6 support seems
pretty solid, but I don't have enough v6 traffic at the moment to really
exercise the box.
I've been nudged toward the 5K series, but have heard the L3 version
isn't ready for prime time (oversubscribed L3 module).
I haven't used any L3 features on the 5Ks, but the L2 / FEX / vPC stuff is
pretty solid. We've had 5Ks in various places for 3 years without any
major blips.
I've been pointed at the 6K series, but somewhat amused by the 40G
"splits" to 10G...
Haven't tried out the 6K yet.
We are currently a 6500-based shop for Core and Border, FWIW.
Our border and core (I'm also in the .edu world) are separated - we don't
carry full routes internally, so I also don't know if any gotchas related
to slinging around large numbers of v4/v6 routes.
