Hello Everyone,
Marc, are you asking about the configs or the bandwidth allocation... or
both?
My comments are on the bandwidth allocation you gave. What speed links are
you using these configs for, and how do you know what bandwidth amount to
give for each class? Interactive and delay sensitive traffic has higher
bandwidth needs.
Citrix, voice, and lotus each have very differnet quality requirements.
Citrix and voice have much tighter quality requirements than Lotus. Will
the bandwidth you provided for Citrix and Voice be sufficient to provide the
quality required by each?
Lotus notes is probably fine with less bandwidth since no one cares if their
email is a second or two late. But... everyone cares if Citrix or voice
calls are delayed and do not get their appropriate quallity.
My suggestion Marc would be to carefully examine your bandwidth allocation
before using these configs.
How much bandwidth you need, is totally determiend by the quality targets
that each traffic class has. Quality targets refer to queuing / buffering
delay, jitter through the network, serialization delay (if present), and
loss percentages.
Kindest Regards Marc and all,
Andrew Lee Lissitz

Subject: QoS config with VOICE, APP, Citrix, lotus sample ( any comments)
I need help. Will this work in a real live situation.
Any comments will be appreciated. This is a point to
point config with servers and clients behind each
router.
Attached are the configs. Currently only bandwidth has
been assigned.
