Subject: [OSL | CCIE_Voice] QoS for Frame Relay
hello, everyone.
I have several questions about the QoS:
1) As I know, the Frame Relay Fragment Size must be always calculated based on
the Interfaces Access Rate? Am I right? And when using the Auto QoS on Frame
Relay Subinteface, it will calculate the Framgent Size based on the "bandwidth"
command under the Subinterface, and then we have to manually correct the
Fragment Size, so that it will be based on the Access Rate and not on the
Bandwidth of an interface, am I right?
2) When configuring the CUCM RSVP CAC, we have to configure the "ip
rsvp bandwidth" command under the Frame Relay DLCI interface, and also
configure the RSVP MTPs on the Routers.
Each G729 call for RSVP is allocating 40 kbps, and for G711 96 kbps.
But now look, I have an issue with the "ip rsvp bandwidth" command:
I have configured the "ip rsvp bandwidth 40" under the Frame Relay DLCI
(Subinterface), so that I have to have only 1 G729 call, and all other calls
should be rejected (Not reserved).
But my routers are still reserving more and more bandwidth for subsequent
calls. RSVP is not rejecting calls, even if I configure the "ip rsvp bandwidth
10" command, the calls are still traversing and are not rejected.
I have also added the following command:
ip rsvp policy preempt
interface Serial0/3/0.1 point-to-point
frame-relay interface-dlci 101
ip rsvp bandwidth 40
ip rsvp data-packet classification none
ip rsvp resource-provider none
But still not succes, even 5 G729 calls are reserved and not rejected. I cannot
understand why is it so? The debugs of RSVP does not show anything interesing,
they are just saying that the RSVP reservation has been succesfull for each
call.
Maybe it is an IOS BUG?
