This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.

CCIE #29033

This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

Quick Notes - NTP Update-Calendar

There are some platforms that have a hardware clock that is powered by a battery. This is in addition to the software based clock. The software clock is synchronized to an external time source via NTP. At times the hardware clock may drift if it is not periodically updated by the software clock. It is best practice to update the hardware clock periodically with the software clock.

"ntp update-calendar" updates the hardware clock
