[c-nsp] Output drops on 2960

[John Gaffney]

We do have a few of those out the in field and they are solid switches. Not a bad thought. Looking at the buffer size table looks like its much fatter than the 2960..

The 3850 and 3650 seem like OK middle ground. Anybody deploy those? They decent?

Thanks,

John

4948Es are pretty good if you need 10/100/1000.
They are also relatively cheap and can be bought used at a good discount.
If you don't need 10/100 then the Nexus 9300 series has a shared 50Mbyte buffer.
But they are relatively pricey and new so used is not really available.

This looks like a great guide.

Looks like I'll be working to replace the switch with something with more power. Any body have a recommendation for a switch with some bigger buffers and 2x 10G uplinks? Need at least 12 Gig ports.

Thanks,

John

I use this list for switch buffers - seems pretty accurate to me:
