Quality of Service configuration Use the Quality of Service (QoS) commands to configure the IEEE 802.1p priority value of incoming packets. This allows you to differentiate between various types of traffic, and provide different priority levels. QoS 802.1p configuration This feature provides the GbE2c Ethernet Blade switch the capability to filter IP packets based on the IEEE 802.1p bits in the packet's VLAN header. The 802.1p bits specify the priority that you should give to the packets while forwarding them. The packets with a higher (non-zero) priority bits are given forwarding preference over packets with numerically lower priority bits value. The following table describes the 802.1p Configuration commands. Table 152 802.1p Configuration commands Command qos transmit-queue mapping qos transmit-queue weight-cos show qos transmit-queue show qos transmit-queue information Description Maps the 802.1p priority of to the Class of Service queue (COSq) priority. Enter the 802.1p priority value (0-7), followed by the Class of Service queue (0-1) that handles the matching traffic. Command mode: Global configuration Configures the weight of the selected Class of Service queue (COSq). Enter the queue number (0-1), followed by the scheduling weight (0-15). Command mode: Global configuration Displays the current 802.1p parameters. Command mode: All except User EXEC Displays the current 802.1p parameters, and the 802.1p priority level for each port. Command mode: All except User EXEC Access Control configuration Use these commands to create Access Control Lists (ACLs) and ACL Groups. ACLs define matching criteria used for IP filtering and Quality of Service functions. Access Control List configuration These commands allow you to define filtering criteria for each Access Control List (ACL). The following table describes the basic ACL Configuration commands. Table 153 ACL Configuration commands Command Description [no] access-control list egress-port Configures the ACL to function on egress packets. The egress port ACL will not match a Layer 2 broadcast or multicast packet. The egress port ACL will not match packets if the destination port is a trunk. Command mode: Global configuration access-control list action {permit|deny|set-priority } Configures a filter action for packets that match the ACL definitions. You can choose to permit (pass) or deny (drop) packets, or set the Class of Service queue that handles the packets. Command mode: Global configuration access-control list statistics Enables or disables the statistics collection for the Access Control List. Command mode: Global configuration default access-control list Resets the ACL parameters to their default values. Command mode: Global configuration show access-control list Displays the current ACL parameters. Command mode: All except User EXEC Configuration Commands 131
