My Current IOS:cat4000-i9s-mz.121-19.EW1.bin
You can upgrade to 12.2(25)EWA to have SSO and get <30s switchovers or 12.2(31)SGA code to support SSO with NSF, to have possible >5s switchovers. Here is the link for 12.2SGA SSO with NSF:
I would suggest to use SSO with NFS between the supervisor engines. SSO/NSF give you sub-milisecond fail-over between the sup's for both L2/L3 failover though we claim it around 0-3 seconds which depends on the traffic flow. My self has tested same with 900Mbps traffic and the failover time was arnd 300 milisecond.
You need atleaset 12.2.31SG for the same.
Have a look at this release notes for supported IOS 12.2(31)SG
