how to test throughput of a switch

[vulcanman]

One of our vendors gave us a Layer3 Switch for eval.

I am looking for some app to test the throughput of that switch.

TIA //

Thank you ... I will check it out //

turn on the span port - run a bunch of iperf's watch the switch crumble as system load peaks. remember to turn all the fancy features on - that is what eats up the cpu.

i've seen switches (Cheap ones) move iscsi fast - simple no config - the same switch trying to handle trunking/span/vlan/etc massively fails.

iirc the cheap switches (low end) procurve to use are the 2910al - and the cisco 2960S (sp?) the new stackwise ones. they are very very expensive but have the ability to share a common redundant power supply (3-6 switches), stacking (cisco stackwise) etc.

if you are just doing basic cheezy gigabit across the board - 2510G-48 is an awesome switch for the price from hp (lifetime warranty remember).

if you are hardcore on a budget and will never ever ever need STP then the 1810G-24 is a great cheapo switch but i'd warn you that its really cheap.

Watch out for dell's "iscsi optimized switches" they are super cheap and if you ask them if they are good for their equallogic they'll say hell no. lol.

Asics aren't cheap. Good ones. Each asic serves a number of ports with a specific power and ram cache - if you have on asic running 16 ports or the same 1 asic running 3 ports you'll feel it when you start crunching that is for sure!

per port packet buffer (non-shared) , ability to do flow control and jumbo packets, 10gbit trunking, stacking (real) are the good things to look for
