Configuring QoS
Beginning in privileged EXEC mode, follow these steps to create an IP extended ACL for IP traffic:
Command
Step 1
configure terminal
Step 2
access-list access-list-number
{deny | permit | remark} protocol
{source source-wildcard | host source |
any } [operator port] {destination
destination-wildcard | host destination |
any} [operator port]
Step 3
end
Step 4
show access-lists
Step 5
copy running-config startup-config
To delete an ACL, use the no access-list access-list-number global configuration command.
78-11380-04
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 deny or permit to specify whether to deny or permit access if
conditions are matched.
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. You specify this 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 source-wildcard, enter the wildcard bits by placing ones in the bit
positions that you want to ignore. You specify the wildcard 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 by 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.
Note
Deny statements are not supported for QoS ACLS. See the
"Classification Based on QoS ACLs" section on page 24-5
more details.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
