[s.ramesh41]

Hi Guys,

we are planning to upgrade IOS of 3750 switches. Currently we are running 12.2(55)SE10.

Could you please let me know which is the next suitable IOS version to upgrade.

As Tausif has already noted, there's 12.2(55)SE11, and that's probably the most stable version for the 3750, although your SE10 is just as about as solid.

I agree, 12.2(55)SE range is, by far, the most stable IOS best suitable for 3560- and 3750-series family of switches.
