Configuring Standard QoS
Classifying Traffic by Using ACLs
You can classify IP traffic by using IP standard or IP extended ACLs; you can classify non-IP traffic by
using Layer 2 MAC ACLs.
Beginning in privileged EXEC mode, follow these steps to create an IP standard ACL for IP traffic:
To delete an access list, use the no access-list access-list-number global configuration command.
This example shows how to allow access for only those hosts on the three specified networks. The
wildcard bits apply to the host portions of the network addresses. Any host with a source address that
does not match the access list statements is rejected.
Switch(config)# access-list 1 permit 192.5.255.0 0.0.0.255
Switch(config)# access-list 1 permit 128.88.0.0 0.0.255.255
Switch(config)# access-list 1 permit 36.0.0.0 0.0.0.255
! (Note: all other access implicitly denied)
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
access-list access-list-number {deny |
permit} source [source-wildcard]
Create an IP standard ACL, repeating the command as many times as
necessary.
• For access-list-number, enter the access list number. The range is
1 to
99 and 1300 to 1999.
• Use the permit keyword to permit a certain type of traffic if the
conditions are matched. Use the deny keyword to deny a certain
type of traffic if conditions are matched.
• For source, enter the network or host from which the packet is
being sent. You can use the any keyword as an abbreviation for
0.0.0.0 255.255.255.255.
• (Optional) For source-wildcard, enter the wildcard bits in dotted
decimal notation to be applied to the source. Place ones in the bit
positions that you want to ignore.
Note When creating an access list, remember that, by default, the end
of the access list contains an implicit deny statement for
everything if it did not find a match before reaching the end.
Step 3
end Return to privileged EXEC mode.
Step 4
show access-lists Verify your entries.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
