Hello All, Any update? I am still waiting for a reply.
Please assist guys. From: "virajith "<[email protected]> Sent: Sat, 21 Sep 2013 07:18:00 To: "[email protected]"<[email protected]> Subject: QOS WAN hi All, I am trying to connect HQ and SB with a 384 k frame relay PVC.Enable FRF.12 link fragmentation and interleave on the Frame Relay connections to fragment large data packets and interleave voice packets to minimize delays. Max delay between fragments should be set at 10 ms . Also provision RTP header compression. Configure LLQ between HQ and SB to ensure voice bearer traffic gets priority queue treatment & voice signalling is guaranteed for 16kbps. Configure the priority queue accomodates up to 4 G729 calls between HQ and SB. Lastly, assume all bearer voice traffic has been marked with traffic CS3. Here are the steps I am following ... ------------------------------------------------------------- 1) Going to serial interface connecting from HQ to SB on the HQ router and changing the BW to 384 R1(conf)#int ser0/1/0.X R1(config-subif)#bandwidth 384 2) Then apply "auto qos voip trust" under the interface R1(conf)#int ser0/1/0.X point-to-point #frame-relay interface-dlci 201 #auto qos voip trust 3) Then after the auto qos trust is applied . I remove no match ip dscp af31 4) add ...priority 47 and bandwidth 16 5) Then remove "no frame-relay ip rtp header-compression" 6) Add the following... map-class frame-relay AutoQoS-FR-Se0/1/0-201 frame-relay cir 364800 frame-relay bc 3648 frame-relay be 0 frame-relay mincir 364800 frame-relay fragment 480 service-policy output AutoQoS-Policy-Trust 7) add "compress ip header rtp" 8) I then move to SB router and do the same steps ( 1-7) on the interface connecting to HQ 9) After this I create a class map on HQ router with Site C map-class frame-relay 2MBPS frame-relay cir 2048000 frame-relay bc 20480 frame-relay be 0 frame-relay mincir 2048000 interface Serial0/1/0.2 point-to-point description *** FR Connected to BR2 *** frame-relay interface-dlci 202 class 2MBPS Problem: ------------------------- 1) My phones in Site C unregister and don't register back after the above configuration. Looks like QOS breaks phone registration 2) The calls between sites appear to be slightly delayed. 3) Audio on the phones seems to be watery. Questions : ------------------------ 1) What is wrong with the above config? 2) Is there an easier and safer way for achieving the task? 3) How can the above task be achieved without causing problems?
