My question is about appling QoS over a frame-relay subinterface. I inherited an MPLS network that has mostly T1s on the CE end of things, but a few locations have frame-relay connections instead. A typical frame-relay setup looks something like this:
On the physical interface:
--------------------------------------------------------------------------- interface Serial0/1/0 bandwidth 1536 no ip address max-reserved-bandwidth 100 encapsulation frame-relay IETF load-interval 30 no fair-queue service-module t1 remote-alarm-enable frame-relay traffic-shaping frame-relay lmi-type ansi hold-queue 40 out
On the subinterface:
---------------------------------------------------------------------------- interface Serial0/1/0.525 point-to-point bandwidth 1536 ip address 10.254.240.2 255.255.255.252 ip verify unicast reverse-path allow-self-ping no ip redirects no ip unreachables ip virtual-reassembly frame-relay interface-dlci 702 class VOIPovFR
The frame-relay map class:
--------------------------------------------------------------------------- map-class frame-relay VOIPovFR frame-relay cir 1536000 frame-relay bc 15360 frame-relay be 0 frame-relay mincir 1536000 service-policy output QOSpolicy
The QoS policy & class maps:
------------------------------------------------------------------------------ class-map match-any REAL-TIME match ip dscp ef class-map match-any CRITICAL-DATA match ip dscp af41 match protocol h323 class-map match-any TRANSACTIONAL-DATA match access-group 110 match access-group 111 (I'm leaving out the access-lists, as they are extensive, and I'm not worried about them right this moment.)
policy-map QOSpoliy description Based on telco's recommended settings class REAL-TIME priority percent 35 police cir percent 35 conform-action transmit exceed-action set-dscp-transmit 0 class CRITICAL-DATA set dscp af41 police cir percent 35 conform-action transmit exceed-action set-dscp-transmit 0 class TRANSACTIONAL-DATA set ip dscp af21 police cir percent 20 conform-action transmit exceed-action set-dscp-transmit 0 class class-default police cir percent 10 conform-action transmit exceed-action transmit
Everything looks OK to me, but since I've not worked with QoS over frame-relay, I'm not 100% sure this is a proper setup. One thing I noticed is that I cannot generate a graph of QoS statistics using SDM, which I have no problem doing with my CEs that are using T1. Is it not possible to use SDM to view those stats, and if not, is there a command-line equivilant?
Thanks.
