Recommended IOS for Switch C2960S and C3750

q-le
Level 2
Level 2

Hi All,

We have several of these WS-C2960S-24PS-L running 12.2(55)SE5  C2960S-universalK9-M and need to upgrade to a better

IOS since we have a sitution where CPU would get to 100% but we have only a few ports connected.

Also we have several of WS-C3750-48P running 12.2(55) SE6 C3750-IPBASEK9-M.

Any recommendation is greatly appreciated.

Quick and Easy Answer:

3750/3600 series:-I recommend a "stable" IOS, then 12.2(55)SE7 .  This is followed by 15.0(2)SE2(If you required 802.1x support) else 12.2(55)SE7 is the best.

2900:- 15.0(2)SE2 works well with 2960/G/S even with 802.1x. 

Plz as of now dont upgrade the switches to 15.0(3)SE3.

Hope this answered your query.
