#WirelessFriday February 2017 – Questions and Responses

February 24, 2017 was #Wireless Friday and the topic was Wi-Fi Optimization. Clients are using more real-time and higher bandwidth applications. Your Wi-Fi network needs adapt to a constantly changing environment. The webinar will include mini-demos on health dashboards, flexible radio assignment, and application prioritization.

Today, we heard from Patrick Croak, Wireless CCIE, who walked us through areas where we could achieve WiFi optimization.  If you would like to review the event recording, please go to catch the recording.

 There were a number of resources mentioned.  Here they are:

 As a next step I’d like to recommend contacting your partner or Cisco account team to schedule a deep-dive or even a WLAN Tuning session.

Questions and Responses:

Q1.  Does the packet capture only work for CAPWAP clients? What about Flexconnect
A1.  Packet capture should work for Flexconnect clients. In a Flexconnect deployment, the AP’s still maintain a CAPWAP tunnel to the WLC, just over a WAN link.

Q2.  When you are specifying packet captures, are you refering to the actual wireless frames or ethernet frames?
A2.  Wireless. The packets are captured and dumped in the order of arrival or transmit of packets except for beacons and probe responses. The packet capture contains information such as channel, RSSI, data rate, SNR, and timestamp.

 Q3.  Should we broadcast or not broadcast our guest wireless SSID in a multitenant environment? Is there any security gained from not broadcasting as the clients will still call out for it. Or does hiding it help reduce potential DoS attacks on the server?
A3.  Many would suggest there is essential no security benefit to not broadcast. Any sniffer can discover that. Most now understand we need to play nice in the same sandbox.

 Q4.  Do you know when the 8.3 code with be a “star” release?
A4.  If you are referring to 8.3 MR1, it was posted February 27, 2017.  Check out the release notes here.

Q5.  Can you talk about TPC versions or is the name the whole story?
A5.  You can review the differences in the following white paper. TPCv1 is most commonly used. http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-3/b_RRM_White_Paper/b_RRM_White_Paper_chapter_0101.html#id_15224 

Q6.  Is the workstation profiling coming from ISE?
A6.  The workstation profiling is coming directly from the controller.

Q7.  Are the adjustments to the 2800 and 3800 series APs available in Cisco Prime Infrastructure?
A7.  Yes

Q8.  What version is being demonstrated?
A8.  Any Version of code after 8.1 will look like this. This code running here is 8.3.

Q9.  When enabling fast transition does the FT 802.1x option need to be enabled in authentication key management?
A9.  Either FT 802.1x or FT PSK. http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/80211r-ft/b-80211r-dg.html#task_2C619E3A576D474F80D6CB4BA8B4DBA6
