Hi Matt (and other helpful posters off list),
Yes, makes sense.

I have used the summit x650s for cloud and they work fine for public and
SAN traffic on the same switch. I have seen then as low as 7k if you can
work with extreme directly. The only downside being the configuration for
large VLAN amounts.
Also netgear makes the xsm7224s which does everything the

I wonder why they filter by IPs anyways?
The only reason I can guess is geolocation to ensure they have a frequency
license in a given geographic area.
However my experience has been that other providers use a GPS for this
(and unfortunately, require a GPS lock to operate). Great for a house wit

By any chance were you querying a Sup32 that had BGP full routes? That and
other large tables can easily swamp the cpu on the Sup32.
This technote is based on IOS, and I don't know if the same facilities exist in
CatOS, but as Nick mentioned, run, don't walk and convert to IOS. CatOS is dead.

Your people will need to come to grips with the fact that just being
able to see light coming out the end of the fiber is no longer
sufficient. Depending on the length you will have to deal with
Chromatic Dispersion and compensation for that. People will need to

You may want to take a look at the Brocade VDX 6720, it provides 16 10gb ports,
with 8 ports on demand with addl license.
They are very reasonable, esp. if you only need 16 ports. Maintenance costs
are less

In the USA the Federal School Lunch program has built out a parallel fiber
network equal to or superior to telco fiber in many urban locations, under

If you're looking at sub 50k, the Nexus 5k isn't a terrible option.
It gives you 32 10Gig SFP slots for ~$25,000 or less if you don't mind
