Load Balancing on 3750

j98me2 · ‎10-08-2009

Does anyone know is it possible to do load balancing between two web servers on a 3750. I know you can on the 6500 and 7200, but I am not really familiar with the 3700 line. Even a work around for the time being would be sufficient.

3750 supports same thing as 6500 regarding etherchannel.

Running nic teaming and load-balancing on the web servers is not enough to get traffic to loadbalance from the switch to the server. But that applies to both 6500 and 3750. You need to run etherchannel, PAgP, LACP or something else on the server.

assuming its IOS Server Load Balancing your meaning...

Basically, you're looking at the Catalyst 6500 series (ie. 6506, 6509, 6513) and the Cisco 7100, 7200, and 7600 series routers (ie. 7603, 7606, 7609).

note that it will also depend on the Supervisor Engine and MFSC models are used within these switches.

check out the Feature Navigator

for SLB to find out code versions ahd platforms etc

Hello Jeremy,

if you mean Server load balancing at OSI level 4 or above I would say no with an exception:

C3750 supports WCCP v2 towards web caches but it is not limited to HTTP traffic.

Hope to help

Hi j98me2.

Unfortunately, Cisco supports server load balance on Cat 6k, 7x00 and the old 3640 router. This functionality is also present on ACE 4700 app control engines.

It would be great to have such a feature back in small routers like the ISR routers. Some times, the platform above are too big/expensive for a small deployment (3 to 6 servers).
