Cisco Network Engineer Blog. Created by Network Engineers for Network Engineers. Sunday, April 3, 2011. Configure QoS Rate Limiting and Priority Queuing Cisco ASA/PIX Firewall. Note: Only packets with normal priority can be policed. Packets with high priority are not policed. Maximum rate for tcp traffic class is 56,000 bits/second, maximum burst size is 10,500 bytes/second. Traffic in the voice class has no policed maximum speed or burst rate because it belongs to a priority class. D-Link DIR-655 Xtreme...
