Configuring QoS
Configuring QoS
To delete an access list, use the no access-list access-list-number global configuration command.
Command Purpose
1. configure terminal Enter global configuration mode.
2. access-list access-list-number permit
protocol { source source-wildcard
destination destination-wildcard }
[ precedence precedence ] [ tos tos ]
[ dscp dscp ]
Note: If you enter a dscp value, you
cannot enter tos or precedence . You
can enter both a tos and a precedence
value with no dscp .
Create an IP extended ACL. Repeat the step as many times as necessary.

For access-list-number , enter the access list number. The range is
100 to 199 and 2000 to 2699.

Always use the permit keyword for ACLs used as match criteria in
QoS policies. QoS policies do not match deny ACLs.

For protocol , enter the name or number of an IP protocol. Use the
question mark (?) to see a list of available protocols. To match any
Internet protocol (including ICMP, TCP, and UDP), enter
ip .

The source is the number of the network or host sending the packet.

The source-wildcard applies wildcard bits to the source.

The destination is the network or host number receiving the packet.

The destination-wildcard applies wildcard bits to the destination.
You can specify source, destination, and wildcards as:

The 32-bit quantity in dotted-decimal format.

The keyword any for 0.0.0.0 255.255.255.255 (any host).

The keyword host for a single host 0.0.0.0.
Other keywords are optional and have these meanings:

precedence —Enter to match packets with a precedence level
specified as a number from 0 to 7 or by name: routine ( 0 ), priority
( 1 ), immediate ( 2 ), flash ( 3 ), flash-override ( 4 ), critical ( 5 ),
internet ( 6 ), network ( 7 ).

tos —Enter to match by type of service level, specified by a number
from 0 to 15 or a name: normal ( 0 ), max-reliability ( 2 ),
max-throughput ( 4 ), min-delay ( 8 ).

dscp —Enter to match packets with the DSCP value specified by a
number from 0 to 63, or use the question mark (?) to see a list of
available values.
or ip access-list extended name Define an extended IPv4 access list using a name, and enter access-list
configuration mode. The
name can be a number from 100 to 199.
In access-list configuration mode, enter permit protocol { source
source-wildcard destination destination-wildcard } [ precedence
precedence ] [ tos tos ] [ dscp dscp ] as defined in Step 2.
3. end Return to privileged EXEC mode.
4. show access-lists Verify your entries.
5. copy running-config startup-config (Optional) Save your entries in the configuration file.
