Cisco extending the timeline for the CCIE certification

Cisco is extending the timeline for the CCIE lab exams and CCIE certification migrations, from February 24th to April 27, 2020. This means that you can take the existing CCIE lab before April 27, or choose to take the new CCIE lab on or after April 27th.

As you may be aware, on January 30, the World Health Organization declared the Coronavirus outbreak a global health emergency. Our thoughts and prayers are with those affected. Cisco has a well-established process to coordinate our efforts during outbreaks like this, and they have been tracking the situation and taking appropriate action during recent days and weeks.  The safety of our  customers, partners and employees is always our priority.

One of the actions taken as a result of the continued spread of the virus, was to close CCIE labs in Hong Kong and Beijing, from February 1 through February 14, 2020. These closures impact the timeline for the transition of the CCIE lab exams planned on February 24, 2020, not just for those planning to test in Beijing or Hong Kong, but for  our customers globally  who have been affected by travel restrictions, business closures and other related circumstances.

Cisco made the decision to delay the migration of existing CCIE certifications to new CCIE certifications until April 27, 2020, when it will transition to the new CCIE lab exams. All other elements of the portfolio transition will take effect as planned on February 24.

Windows 802.1X supplicant debugging

I got involved in a complicated issue with a Cisco ISE implementation, and to understand what the endpoint (windows) was doing had to debug the 802.1x on the ccommand line.

Look to all interfaces in the current OS stack and providers

netsh trace show interfacesnetsh trace show providers

netsh lan set tracing mode=[yes|no|persistent]

Capture all info to the tracefile trace.etl, make sure you have the right providers

netsh trace start capture=yes tracefile=C:\trace.etl provider=[microsoft-windows-wired-autoconfig|microsoft-windows-wlan-autoconfig|microsoft-windows-onex]

 

Time to stop the capture and and find the root cause :)

netsh trace stop

Redundant interfaces not supported on FXOS platforms

The documentation might get you a bit confused, but after have a chat with Cisco TAC they shed some light…..Unfortunately this design is not supported, so if you are migrating from a Old Cisco ASA platform it’s time to redesign and avoid redundant interfaces. So i had to move those interfaces to port-channel, so the trade-off was the failover if the principal switch died.
