Enabling Admission Control
This section describes how to enable admission control on an SSID.
For a list of Cisco IOS commands for enabling admission control using the CLI, consult the Cisco IOS
Command Reference for Cisco Aironet Access Points and Bridges.
Follow these steps to enable admission control on an SSID:
Step 1 Open the SSID Manager page.
Step 2 Select an SSID.
Step 3 Under General Settings, select Enable in the Call Admission Control field.
Troubleshooting Admission Control
You can use two CLI commands to display information to help you troubleshoot admission control
problems:
• To display current admission control settings on radio 0, enter the following command:
# show dot11 cac int dot11Radio 0
• To display current admission control settings on radio 1, enter the following command:
# show dot11 cac int dot11Radio 1
• To display information about admitted streams with admission control and MT, enter the following
command:
# show dot11 traffic-streams
QoS Configuration Examples
These sections describe two common uses for QoS:
• Giving Priority to Voice Traffic, page 15-13
• Giving Priority to Video Traffic, page 15-14
Giving Priority to Voice Traffic
This section demonstrates how you can apply a QoS policy to your wireless networks’ voice VLAN to
give priority to wireless phone traffic.
In this example, the network administrator creates a policy named voice_policy that applies voice class
of service to traffic from Spectralink phones (protocol 119 packets). The user applies the voice_policy
to the incoming and outgoing radio ports and to the outgoing Ethernet port. Figure 15-5 shows the
administrator’s QoS Policies page.
