Configuring Standard QoS Chapter 30 Configuring QoS Beginning in privileged EXEC mode, follow these steps to create an IP extended ACL for IP traffic: Step 1 Step 2 Command configure terminal access-list access-list-number {permit | remark} protocol {source source-wildcard | host source | any} [operator port] {destination destination-wildcard | host destination | any} [operator port] [dscp dscp-value] [time-range time-range-name] Step 3 end Purpose Enter global configuration mode. Create an IP extended ACL, repeating the command as many times as necessary. For access-list-number, enter the ACL number. The range is 100 to 199 and 2000 to 2699. Enter permit to permit access if conditions are matched. Enter remark to specify an ACL entry comment up to 100 characters. Note Deny statements are not supported for QoS ACLs. See the "Classification Based on QoS ACLs" section on page 30-5 for more details. For protocol, enter the name or number of an IP protocol. Use the question mark (?) to see a list of available protocol keywords. For source, enter the network or host from which the packet is being sent. For source-wildcard, enter the wildcard bits by placing ones in the bit positions that you want to ignore. You specify the source and source-wilcard by using dotted decimal notation, by using the any keyword as an abbreviation for source 0.0.0.0 source-wildcard 255.255.255.255, or by using the host keyword for source 0.0.0.0. For destination, enter the network or host to which the packet is being sent. You have the same options for specifying the destination and destination-wildcard as those described for source and source-wildcard. Define a destination or source port. • The operator can be only eq (equal). • If operator is after source source-wildcard, conditions match when the source port matches the defined port. • If operator is after destination destination-wildcard, conditions match when the destination port matches the defined port. • The port is a decimal number or name of a TCP or UDP port. The number can be from 0 to 65535. • Use TCP port names only for TCP traffic. • Use UDP port names only for UDP traffic. Enter dscp to match packets with any of the 13 supported DSCP values (0, 8, 10, 16, 18, 24, 26, 32, 34, 40, 46, 48, and 56) or use the question mark (?) to see a list of available values. The time-range keyword is optional. For information about this keyword, see the "Applying Time Ranges to ACLs" section on page 29-15. Return to privileged EXEC mode. 30-28 Catalyst 2950 and Catalyst 2955 Switch Software Configuration Guide 78-11380-10
