Thanks Kobel for your explanation. It does make sense to me that small voice packets do not grow in size to the point of being fragmented. The only thing that I'm not too sure is whether or not this would be something that Cisco would be expecting to see as a valid answer if such a question was asked in the exam. I guess I would ask the proctor because the lab exam is usually far from reality.
Hello Mouhammad I disagree with your statement "Finally, I know that both LLQ and "ip rsvp bandwith" values must be identical and calculated as = (N-1) calls at 20 mSec + 1 call at 10 mSec" Why would you always match those two values? Are you calculating these with or without layer 2 overhead? There is an example in the UCM 7 SRND page 3-64 which describes RSVP calculation examples without taking any layer 2 overhad into account. There is a note on page 3-64 that states Unified CM does not include SRTP overhead or the L2 overhead int he RSVP reservation. and then it says that the layer 3 IP rsvp bw statement must take into account any SRTP traffic and the L2 priority queue must also be over-provisioned if SRTP is present. How do you guys interpret this and what should we do to get those precious points in the exam?? 2010/6/28 Mouhammad Nasser <engnasse...@hotmail.com> > Hi Kobel, > > The worst case takes a place upon the initialization of each RSVP call > calculation, CUCM 7.0 LLD refers that amond N calls, it is recommended to > calculate call number N as worst case, so it always succeeds (written in > P.3-64 "Configuration Recommendation") > > > Regarding the number of bytes in FRF.12 header, do you recommend we always > consider it a 4 Bytes?
