I have a customer who's outbound interface is a FE interface configured for 100MBs. The actual circuit is only about 11MB download and just barely 1MB upload. The policy map they had configured on their interface wasn't being triggered before the link was saturated due to the big difference in interface line speed and the actual circuit bandwidth. This was causing a problem with their voice services. I since configure a hiearchal policy-map that is shown below. I'm just now trying to verify that its working properly or if I have configure it wrong.
Policy Map Wan-Shaping-1MB-Upload Class class-default Traffic Shaping Average Rate Traffic Shaping CIR 800000 (bps) Max. Buffers Limit 1000 (Packets) Bc 8000 Be 0 service-policy WAN-OUTBOUND-PMAP
Policy Map WAN-OUTBOUND-PMAP Class MATCH-EF-CMAP Strict Priority Bandwidth 70 (%) Class MATCH-CS3-AF31-CMAP Bandwidth 5 (%) Max Threshold 64 (packets) Class class-default Flow based Fair Queueing Bandwidth 0 (kbps) exponential weight 9 explicit congestion notification class min-threshold max-threshold mark-probablity ----------------------------------------------------------
The above policy map was added to their WAN port fa4. When I do a sho policy interface fa4, it has consistently shown that shaping is not active (which could just mean that the bandwidth hasn't gotten that high yet) I was just hoping someone could maybe help me confirm prior to them having problems that this would solve what issue they had. I've posted the output of the show policy-map interface fa4 for you to look over. Thanks!
You have queued 11 packets which means that the shaper was active but only for a short duration.
The configs looks good and should shape to 800k with no burst capabilites. having shaped to 80% bandwidth is good as well so shaper will get active just before it hits the roof on the upload limits. If the service provider allows an occasional burst you might want to give a Be value based on that.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
