You can only apply traffic-shaping to outbound traffic...... The best you could do is setup policing to limit incoming traffic......
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/qos_c /qcpart4/qcpolts.htm (watch for URL wrap) ---------------------------- To get to you question, Ira, voice traffic should be using RTP protocol, so you can differentiate between voice and regular data using that fact. There are different queueing methods you could use, i.e. you could setup a Priority Queue with voice traffic having the highest priority (even at the expense of other traffic), or you could setup LLQ that has a strict priority queue for voice and then uses CBWFQ for the rest of the data (if you define any other classes). Although this document is called "Congestion Management", it covers virtually all of the queueing methods you may want to use for your purpose. http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fqos _c/fqcprt2/qcfconmg.htm (again, watch for URL wrap) Depending on the bandwidth of the WAN link (if it's under 2Mbps), then WFQ is enabled by default. You should be able to use the 'ip rtp priority' to configure a strict priority queue for RTP (voice) traffic. Also, depending on the bandwidth (if its less than 768Kbps) you'll want to (need to) use some kind of Link Fragmentation and Interleaving (LFI). If your WAN connection is Frame Relay, you can use FRF.12 to do this, although check the archives and you'll see people had problems getting it to work as advertised (there was simple solution but I can't remember it offhand). However, the other method for LFI is to configure the WAN link as a Multilink PPP connection (even if it's only one line) because Multilink PPP has a LFI facility built-in. The reason you want LFI on links less than 768Kbps is because smaller (40-80byte) voice packets can be delayed too much when they get in the queue behind a 1500 byte packet of regular traffic (because of the slow speed, the serialization delay for 1500 byte packets get large). Here are some links to help you get started.
