[c-nsp] UBR+ and service-policy on ATM PVCs

[Brian Turnbow]

In order to use qos on atm pvc  you need to use abr/vbr/cbr

UBR and + are for best effort services offering no bandwidth guarantee so you cannot utilize the service policy

That said we mainly use 12.2(31)SB11

Hi all,

I am trying to find the right IOS version to use on
7200s w/ NPE-400/NPE-G1 that both support UBR+ and
QoS (service policies) on a per-vc basis.

Today we use 12.2(16)B2 to terminate ATM PVCs (from xDSL
lines) on these routers, it works fine. But this (old) version
lacks QoS support.

When testing newer versions (I tried 12.3 & 12.4 mainline, 12.2SB,
12.4T) that could support QoS, we rise an issue with UBR+.
Commands are accepted but ignored, and PVCs get configured with
UBR at physical linerate.

ATM interfaces are PA-A3-OC3MM w/ hardware version 2.0.

Which IOS version should we use?

Thanks.
