[c-nsp] 7507 IOS ver. recommendation: 12.0S or 12.2S or whatever?

[Masood Ahmad Shah]

It's just not new features. New release contains new features and bug fixes
from an older version. 

 

FYI.. I'm mentioning some of the 12.0 bugs URL:-

Unless there are features you need in 12.4, use 12.0. And make sure all your
cards are vips to get the benifits of dcef.
12.0(32)SY is pretty good.

Hi folks,



Please, I need your advice. Which IOS ver. is mostly recommended for
7507 running mostly as an ethernet customer access router? 



Our hardware configs are: 7507, dual RSP4 256D/32+F, VIP2-50s w/ PA-FE-TXs,
old serials (FSIPs).



Our feature config is a standard provider package: lots ISL/dot1q customer
subintefaces, dCEF, BGP4, netflow ver. 5 , ACLs. 

And a little bit of some service stuff that we can switch off if needed for
moving to the right image: NAT, GRE, NBAR, rate-limit, traffic-shaper. So,
we are IPv4 only, no IPv6, no MPLS, no non-IP stuff.





Today I noticed our cybuses are upto ~100mbps load, so dCEF is definitely
not working for us, that's the reason why we should switch IOS version.
Also, it turned out today our dCEF really suffer from named-ACLs bug. Oh, 
yes.





Please, advise.





Thank you, indeed.
