Hi list, I will problably receive a rsp720-3CXL 10G to replace an rsp720-3C-GE later this week, and I am curious if any of of you can give me advice on which IOS version to go for.. I see I can choose from SRC,SRC1,SRC2 and SRD versions. Anyone has good/bad experiences with one of the above? Tnx, Martin
