All these IOS versions support the hardware you have.

11.2(6)P, 11.3(1), 11.3(1)T, 12.0(1), 12.0(7)T, 12.0(2)XC, 12.0(2)XD, 12.0(7)XK, 12.1(1), 12.1(1)T, 12.1(5)YB, 12.1(5)YD, 12.2(1), 12.2(2)T, 12.2(2)XT, 12.2(11)YT, 12.2(15)ZJ, 12.3(1)

I would recommend running 12.2(15)ZJ or if you have enough memory (DRAM and flash) upgrade to 12.3.

Hello.

your you can use this tool the Cisco TAC

Configurations tools ===> Software Advisor

Chose Major IOS - prefferably GD.

(due to the stability issues).

I know that 12.1(20) is GD.

Choos 12.2(19) for example.

At the latest possible case choos ReleaseYZ

and at the latest latest possible choose T.

Just go to the IOS upgrade tool and choose

only GD if possible.

But first check with feature navigator for

hardware/software preferences.

This config seems to me prety normal, so

probably 12.1(20) will work or if you need features 12.2(19).
