[c-nsp] Cisco 6509-V-E switch sup2t engine recommend IOS version

[Xuhu NSP]

Hi folks, we are starting to use this platform, any idea which IOS version is quite stable? I checked in Cisco down website saying suggested version is 15.0.1-sy7a.

Our feature requirement is quite simple, normal QOS marking and WRR, layer 2 switching is needed also.

Br,
