Hello, we have cisco switches 6500 in VSS mode, the sup we have is sup 720-10GB. we run the 12.2(33)SXI6, I am working on QoS and I read in the following url : http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/qos.html which seems to be the right one about the QoS available on a 6500 in a LAN, that : priority queuing and shaping is mutually exclusive. is that really so ? in fact that sentence is in the paragraph : " Allocating Bandwidth Between Standard Transmit Queues " and the exact text is : " ... Enter the shape keyword to configure SRR. Use of SRR prevents use of the strict priority queue. To configure SRR, any CoS or DSCP values mapped to a strict-priority queue must be remapped to a standard queue ... " we have found that the Ethernet service plus board for 6500 support hierarchical QoS policies, url : http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/data_sheet_c78-643759.html but it is a WAN board, and cisco Q & A link about 6500 & VSS : http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps9336/prod_qas0900aecd806ed74b.html states : "WAN Modules : currently not supported" So is there a possiblity (new version, hardware, etc. ?) in which priority queuing is possible along with shaping ? The reason we need it is that the security equipment that is just after the 6500 VSS is not line rate, so we need to shape at a bandwidth in which the security equipment won't drop packets at random and within the traffic there is TOIP and videoconferencing needing a priority queue. Hierarchical  QoS policies would be ideal but it is still a dream and we would be pleased to shape individually every class except strict priority one, to make sure the traffic remains below the dropping threshold of the security equipment. ...
