VLANs and Cisco Autonomous Access Points

Segment wireless voice and data into separate VLANs.
A subnet for wireless clients should not exceed 1,000 hosts.
When using Cisco Autonomous Access Points, use a dedicated native VLAN. The Cisco Autonomous Access Points utilize
Inter-Access Point Protocol (IAPP), which is a multicast protocol.
For the native VLAN, it is recommended not to use VLAN 1 to ensure that IAPP packets are exchanged successfully.
Ensure that Public Secure Packet Forwarding (PSPF) is not enabled for the voice VLAN as this will prevent clients from
communicating directly when associated to the same access point. If PSPF is enabled, then the result will be no way audio.
Port security should be disabled on switch ports that Cisco Autonomous Access Points are directly connected to.
The network ID in the SSID configuration the Cisco Autonomous Access Point should only be disabled if Layer 3 mobility is
enabled where the Wireless LAN Services Module (WLSM) is deployed.

Configuring the Cisco Unified IP Phone 9971

To configure the Wi-Fi settings on the Cisco Unified IP Phone 9971, use the keypad and touch screen to navigate to
Applications Button > Administrator Settings > Network Setup > WLAN Setup.

Wireless LAN Settings

Use the following guidelines to configure the wireless LAN profile.
Ensure that Wireless is set to On.
•
WLAN Sign in Access can be set to On to give shortcut access in the Applications Menu in order to update the
•
username or password.
Enter the SSID for the voice wireless LAN, which is case sensitive.
•
The Cisco Unified IP Phone 9971 supports a single wireless LAN profile that allows a single SSID.
3 different 802.11 modes are available.
•
• Auto
• 802.11a
• 802.11b/g
Auto mode will scan both 2.4 and 5 GHz channels and attempt to associate to the access point with a 5 GHz signal if
the configured network is available.
802.11a mode will only scan 5 GHz channels and 802.11b/g mode will only scan 2.4 GHz channels, then will attempt
to associate to an access point if the configured network is available.
