[c-nsp] 12.2(28)SB on C7200 as LNS (w/ per-session QoS) - real-life experiences?

[Johannes Resch]

hi,

according to cisco release notes, 12.2(28)SB introduces an interesting 
feature, per-session QoS with CBWFQ-support [0].

is anyone already using this on a 7200-based LNS?

i'd be interested in your experiences, especially on limitations and 
performance in comparison to 12.3 mainline.

also, the performance impact due to the additional QoS features would be 
interesting. a 7200VXR/NPE-G1 with 12.3 and no fancy features can handle 
at least 7.5k L2TP/PPPoE sessions; which impact on session numbers would 
i have to expect on the same hardware with 12.2(28)SB and CBWFQ on 
_every_ user session?

regards,
-jr
