Battery Boost
Battery boost is an optional feature that can be enabled for any SSIDs Service Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network. that support voice traffic. This feature converts all broadcast and multicast traffic to unicast before delivery to the client. Enabling battery boost on an SSID Service Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network. allows you to set the DTIM Delivery Traffic Indication Message. DTIM is a kind of traffic indication map. A DTIM interval determines when the APs must deliver broadcast and multicast frames to their associated clients in power save mode. interval from 10 to 100 (the previous allowed values were 1 or 2), equating to 1,000 to 10,000 milliseconds. This longer interval keeps associated wireless clients from activating their radios for multicast indication and delivery, leaving them in power-save mode longer, and thus lengthening battery life. The DTIM Delivery Traffic Indication Message. DTIM is a kind of traffic indication map. A DTIM interval determines when the APs must deliver broadcast and multicast frames to their associated clients in power save mode. configuration is performed on the WLAN Wireless Local Area Network. WLAN is a 802.11 standards-based LAN that the users access through a wireless connection., so no configuration is necessary on the client.
An associated parameter available on some clients is the listening interval. This defines the interval (in number of beacons) after which the client must wake to read the TIM Traffic Indication Map. TIM is an information element that advertises if any associated stations have buffered unicast frames. APs periodically send the TIM within a beacon to identify the stations that are using power saving mode and the stations that have undelivered data buffered on the AP. . The TIM Traffic Indication Map. TIM is an information element that advertises if any associated stations have buffered unicast frames. APs periodically send the TIM within a beacon to identify the stations that are using power saving mode and the stations that have undelivered data buffered on the AP. indicates whether there is buffered unicast traffic for each sleeping client. With battery boost enabled, the DTIM Delivery Traffic Indication Message. DTIM is a kind of traffic indication map. A DTIM interval determines when the APs must deliver broadcast and multicast frames to their associated clients in power save mode. is increased but multicast traffic is buffered and delivered as unicast. Increasing the LI Lawful Interception. LI refers to the procedure of obtaining communications network data by the Law Enforcement Agencies for the purpose of analysis or evidence. can further increase battery life, but can also decrease client responsiveness.

Do not enable battery boost if your network includes Polycom SpectraLink devices that use the Push-to-Talk feature. |
The following procedure describes how to enable the battery boost feature and set the DTIM Delivery Traffic Indication Message. DTIM is a kind of traffic indication map. A DTIM interval determines when the APs must deliver broadcast and multicast frames to their associated clients in power save mode. interval in the SSID Service Set Identifier. SSID is a name given to a WLAN and is used by the client to access a WLAN network. profile:
1. In the node hierarchy, navigate to .
2. In , expand . Select the profile.
This example uses the default profile.
3. In , change the to a longer interval time.
4. Select the check box.
5. Click .
6. Click .
7. In the window, select the check box and click .
The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. commands configure battery boost:
(host) [md] (config) #wlan ssid-profile defaultwlan ssid-profile <profile>
(host) ^[md] (SSID Profile "default") #battery-boost
(host) ^[md] (SSID Profile "default") #dtim-period <dtim-period>
