Configuring QoS
You should not configure any standard QoS commands before entering the auto-QoS commands. You
Note
can fine-tune the QoS configuration, but we recommend that you do so only after the auto-QoS
configuration is completed.
Beginning in privileged EXEC mode, follow these steps to configure the switch at the edge of the QoS
domain to prioritize the VoIP traffic over all other traffic:
Command
Step 1
debug auto qos
Step 2
configure terminal
Step 3
cdp enable
Step 4
interface interface-id
Step 5
auto qos voip cisco-phone
Step 6
exit
Step 7
Step 8
interface interface-id
Step 9
auto qos voip trust
Step 10
end
Step 11
show auto qos
Step 12
copy running-config
startup-config
OL-8550-02
Purpose
Enable debugging for auto-QoS. When debugging is enabled, the
switch displays the QoS configuration that is automatically
generated when auto-QoS is enabled.
Enter global configuration mode.
Enable CDP globally. By default, it is enabled.
Specify the switch port connected to the Cisco IP Phone, and enter
interface configuration mode.
Enable auto-QoS on the port, and specify that the port is connected
to a Cisco IP Phone.
The QoS labels of incoming packets are trusted only when the
Cisco IP Phone is detected.
Return to global configuration mode.
Repeat Steps 4 to 6 for as many ports as are connected to the Cisco
IP Phone.
Specify the switch port identified as connected to a trusted switch
or router, and enter interface configuration mode. See
Figure
33-11.
Enable auto-QoS on the port, and specify that the port is connected
to a trusted router or switch.
Return to privileged EXEC mode.
Verify your entries.
This command displays the auto-QoS command on the interface
on which auto-QoS was enabled. You can use the show
running-config privileged EXEC command to display the
auto-QoS configuration and the user modifications.
For information about the QoS configuration that might be
affected by auto-QoS, see the "Displaying Auto-QoS Information"
section on page 26-12.
Save the auto qos voip interface configuration commands and the
generated auto-QoS configuration in the configuration file.
