Chapter 4 Configuring Controller Settings
Configuring EDCA Parameters
Using the CLI to Configure EDCA Parameters
To configure EDCA parameters using the controller CLI, follow these steps:
Step 1 Disable the radio network by entering this command:
config {802.11a | 802.11b} disable network
Step 2 Save your settings by entering this command:
save config
Step 3 Enable a specific EDCA profile by entering this command:
config advanced {802.11a | 802.11b} edca-parameters ?
where ? is one of the following:
• wmm-default—Enables the Wi-Fi Multimedia (WMM) default parameters. This is the default
value. Choose this option when voice or video services are not deployed on your network.
• svp-voice—Enables SpectraLink voice priority parameters. Choose this option if SpectraLink
phones are deployed on your network to improve the quality of calls.
• optimized-voice—Enables EDCA voice-optimized profile parameters. Choose this option when
voice services other than SpectraLink are deployed on your network.
• optimized-video-voice—Enables EDCA voice- and video-optimized profile parameters. Choose
this option when both voice and video services are deployed on your network.
Note If you deploy video services, admission control (ACM) must be disabled.
• custom-voice—Enables custom voice EDCA parameters for 802.11a. The EDCA parameters under
this option also match the 6.0 WMM EDCA parameters when this profile is applied.
Step 4 View the current status of MAC optimization for voice by entering this command:
show {802.11a | 802.11b}
Information similar to the following appears:
Voice-mac-optimization...................Disabled
Step 5 Enable or disable MAC optimization for voice by entering this command:
config advanced {802.11a | 802.11b} voice-mac-optimization {enable | disable}
This feature enhances voice performance by controlling packet retransmits and appropriately aging out
voice packets on lightweight access points, which improves the number of voice calls serviced per access
point. The default value is disabled.
Step 6 Reenable the radio network by entering this command:
config {802.11a | 802.11b} enable network
Step 7 Save your settings by entering this command:
save config
