    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

Cisco Wireless IP Phone (7921 / 7925) 1.3(4) Firmware Released

 

 

I've been a sleep at the wheel this week, busy with work, study and more work. Some interesting highlights in this release. WPA2 now supported with CCKM and Hardware Diagnostics!

Early reports from the forums I troll is that battery life appears to be less with this level of code. Also reports of better roaming are mentioned. Anyone out there testing this !? Would love to hear your feedback.

Hardware Diagnostics

Cisco Unified Wireless IP Phones are frequently returned and a replacement is requested when the phone is operational. In firmware 1.3(4), a self-diagnostic tool is available to determine if a valid hardware issue exists.

You can access the Diagnostics menu from the Phone Settings menu, where the Keypad, Speaker, Microphone and WLAN Radio and Antenna can be validated.

The WLAN diagnostics menu is the standard site survey utility, which will use the current network profile information to scan for the configured network.

Full CCKM Support

Cisco Centralized Key Management (CCKM) reduces the amount of delay time by centralizing the key management, which reduces the number of key exchanges. To optimize secure roaming, CCKM can be enabled while in WPA or WPA2 mode.

Prior to this firmware release, CCKM was not supported when WPA2/AES was selected; this required a full re-authentication when roaming between access points, and could result in loss of audio during the roam. Now that CCKM is supported when WPA2/AES is selected, the full re-authentication is no longer required and roaming to a new access point should not result in any perceptible loss of audio.

Firmware 1.3(4) provides full CCKM support of all WPA versions.

I have always understood that CCKM is limited to TKIP, but this does not seem to be true based on your article and this firmware update. Was the CCKM/TKIP restriction limited to Cisco VoIP phones in the past, or was this a pervasive problem?

March 17, 2010 | Unregistered CommenterMarcus

Marcus, prior to this version of code, CCKM was ONLY supported with WPA/TKIP on the Cisco 7921 and 7925 handsets. This latest release, WPA2/AES is supported with CCKM. This was a specific limitation to the phones as you could always config this setting on the WLC.
