Recommended Stable IOS for 3750 / 2960

[zykobot]

Hi Guys,

Can I please have a recommendation on the most stable release of IOS to use for Cat 3750 and 2960 switches.

The 3750s will be stacked.

The 2960s will be used for DMZ switching.

Thanks,

Nick.

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.

Hope this answered your query.

3560/3750:  If you are using 802.1X & Layer 3, use 12.2(55)SE7.  If you are not, then 15.0(2)SE2 is OK for LAYER 2.

2960:  15.02(2)SE2 is a good release.

Currently testing 12.2(55)SE8 and 15.0(2)SE4.  So far so good.  Will let you know in 10 days time how it goes.

upgraded to 12.2(55)SE8 last week on the 2960S stack.

It crashed again this morning:  Which IOS version is more stable?  Will it be hardware related?  Thanks!

If it's crashed, then there should be a crashinfo file(s).

Create a new thread and attach the file(s).

if you not have this command you need to contact the TAC:
