As you have seen lately on the blog I’ve been fiddling around in Python. One of the best resources out there to learn Python for Network Engineers is the free e-mail course by Kirk Byers. Kirk is a CCIE emeritus with extensive knowledge and experience of Python. He offers both free and paid courses over at his site. Kirk is very active in the community and the guy behind Netmiko and the IOS driver in NAPALM. He’s also an active member of the Network to Code Slack group. I recommend that you check out Kirk’s stuff!
I plan to go through all of his exercices and write about them on my blog. That will help me in my learning and hopefully it can help you as well. Kirk publishes the answers to the exercises at Github but my plan is to be a bit more verbose and explain the code. I plan to write my posts here and also put up my answers on Github to get some exposure to using Git. My code will likely not be elegant, the most effective or good looking but hopefully we can learn from each other as I put these posts up. I Continue reading
It started somewhat innocently. Cisco released a field notice that there was an issue with some signal clocks on a range of their networking devices. This by itself was a huge issue. There had been rumblings about this issue for a few months. Some proactive replacement of affected devices to test things. Followed by panicked customer visits when the news broke on February 2nd. Cisco looked like they were about to get a black eye.
The big question that arose was whether or not this issue was specific to Cisco devices or if it was an issue that was much bigger. Some investigative work from enterprising folks like Tony Mattke (@tonhe) found that there was a spec document from Intel that listed a specific issue with the Intel Atom C2000 System on Chip (SoC) that caused it to fail to provide clock signal for onboard chips. The more digging that was done, the more dire this issue turned out to be.
Clock signaling is very important in modern electronics. It ensures that all the chips on the board are using the correct timing to process electronic impulses. If the clock signal starts drifting, you start Continue reading
