  • Page 22: Configuring Cisco Ios Access Points

    Configuring Cisco IOS Access Points Use the following QoS policy on the Cisco IOS access point (AP) to enable DSCP to CoS (UP) mapping. This allows packets to be placed into the proper queue as long as those packets are marked correctly when received at the access point level.

  • Page 23: Sample Voice Packet Capture

    • The Cisco Unified IP Phone 9971 will auto-negotiate the PHY rate to be used for TSPEC. By default it will try 12 Mbps, but if not enabled on the access point, then it will try the next highest enabled data rate on the access point.

  • Page 24: Pre-Call Admission Control

    If the AP sends an ADDTS successful message then the Cisco Unified IP Phone 9971 establishes the call. If the access point rejects the call and the Cisco Unified IP Phone 9971 has no other access point to roam to, then the phone will display Network Busy.

  • Page 25: Roaming

    For seamless roaming to occur, the Cisco Unified IP Phone 9971 must be associated to an access point for at least 3 seconds, otherwise roams can occur based on packet loss (max tx retransmissions or missed beacons).

    5 GHz over 2.4 GHz. At power on, the Cisco Unified IP Phone 9971 will scan all 2.4 and 5 GHz channels when in Auto mode, then attempt to associate to an access point for the configured network if available.

  • Page 27: Using Dynamic Frequency Selection (Dfs) On Access Points

    802.11a environment, which allows for seamless roaming. For critical areas, it is recommended to increase the overlap (30% or more) to ensure that there can be at least 2 access points available with -67 dBm or better, while the Cisco Unified IP Phone 9971 also meets the access point’s receiver sensitivity (required signal level for the current data rate).

  • Page 28: Ghz (802.11B/G)

    There are only 3 non-overlapping channels in the 2.4 GHz frequency range (channels 1, 6, 11). In Japan, channel 14 can be utilized as a fourth non-overlapping channel when using 802.11b access points. Cisco Unified IP Phone 9971 Wireless LAN Deployment Guide...

  • Page 29: Signal Strength And Coverage

    Signal Strength and Coverage To ensure acceptable voice quality, the Cisco Unified IP Phone 9971 should always have a signal of -67 dBm or higher when using 2.4 GHz or 5 GHz, while the Cisco Unified IP Phone 9971 also meets the access point’s receiver sensitivity required signal level for the transmitted data rate.

  • Page 33: Call Capacity

    Design the network to accommodate the desired call capacity. The Cisco Access Point can support up to 27 bi-directional voice streams for both 802.11a and 802.11g at a data rate of 24 Mbps or higher. To achieve this capacity, there must be minimal wireless LAN background traffic and radio frequency (RF) utilization.

  • Page 34: Dynamic Transmit Power Control (Dtpc)

    DTPC prevents one-way audio when RF traffic is heard in one direction only. If the access point does not support DTPC, then the Cisco Unified IP Phone 9971 will use the highest available transmit power depending on the current channel and data rate.

  • Page 35: Multipath

    Due to the potential of elevated multipath in rugged environments, the transmit power of the access point and Cisco Unified IP Phone 9971 should also be restricted. This is more important if planning to deploy 2.4 GHz in a rugged environment.

  • Page 57: Ssid / Wlan Settings

    SSID / WLAN Settings It is recommended to have a separate SSID for the Cisco Unified IP Phone 9971. However, if there is an existing SSID configured to support voice capable Cisco Wireless LAN endpoints already, then that WLAN can be utilized instead.
  • Page 58 The SSID to be used by the Cisco Unified IP Phone 9971 can be configured to only apply to a certain 802.11 radio type. It is recommended to have the Cisco Unified IP Phone 9971 operate on the 5 GHz band due to have many channels available and not as many interferers as the 2.4 GHz band has.

Recommended to set 12 Mbps as the mandatory (basic) rate and 18-24 or 18-54 Mbps as supported (optional) rates; however some environments may require 6 Mbps to be enabled as a mandatory (basic) rate.

  • Page 65: Beamforming (Clientlink)

    For releases prior to 7.2.103.0, ClientLink can be enabled globally via the 802.11 Global Parameters section or on individual access points via the access point’s 802.11 radio configuration page. As of release 7.2.103.0, ClientLink is no longer configurable via the Cisco Unified Wireless LAN Controller’s web interface and is only configurable via command line.

  • Page 66: Auto Rf (Rrm)

    Auto RF (RRM) When using the Cisco Unified Wireless LAN Controller it is recommended to enable Auto RF to manage the channel and transmit power settings. Configure the access point transmit power level assignment method for either 5 or 2.4 GHz depending on which frequency band is to be utilized.
  • Page 67 If using 2.4 GHz, only channels 1, 6, and 11 should be enabled in the DCA list. It is recommended to configure the 2.4 GHz channel for 20 MHz even if using Cisco 802.11n Access Points capable of 40 MHz due to the limited number of channels available in 2.4 GHz.

  • Page 68: Client Roaming

    It is recommended to use 40 MHz channels only if using 5 GHz. Client Roaming The Cisco Unified IP Phone 9971 does not utilize the RF parameters in the Client Roaming section of the Cisco Unified Wireless LAN Controller as scanning and roaming is managed independently by the phone itself.
  • Page 69 The Cisco Unified IP Phone 9971 uses TCP for SIP communications, therefore if the channel is busy where another call can not be allowed, then the Cisco Unified IP Phone 9971 could potentially lose registration to the Cisco Unified Communications Manager.
