This post will describe the exercises and solutions for week two of Kirk Byers Python for Network Engineers.
Our next task is to parse data from show version
from a device.
II. Parse the below 'show version' data and obtain the following items (vendor, model, os_version, uptime, and serial_number). Try to make your string parsing generic i.e. it would work for other Cisco IOS devices. The following are reasonable strings to look for: 'Cisco IOS Software' for vendor and os_version 'bytes of memory' for model 'Processor board ID' for serial_number ' uptime is ' for uptime Store these variables (vendor, model, os_version, uptime, and serial_number) in a dictionary. Print the dictionary to standard output when done. Note, "Cisco IOS Software...Version 15.0(1)M4...(fc1)" is one line. >>>>> show version data <<<<< Cisco IOS Software, C880 Software (C880DATA-UNIVERSALK9-M), Version 15.0(1)M4, RELEASE SOFTWARE (fc1) Technical Support: Copyright (c) 1986-2010 by Cisco Systems, Inc.

A vendor’s SDN solution ecosystem strategy and partnerships can make the difference between long term SDN success, including lifecycle ROI protection, and failure.
Networking is done. The way you have done things before is finished. The writing has been on the wall for quite a while now. But it’s going to be a good thing.
Networking purchase models look much different today than they have in the past. Enterprises no long buy a switch or a router. Instead, they buy solution packages. The minimum purchase unit is a networking pod or rack. Perhaps your proof-of-concept minimum is a leaf-spine of no less than 3 switches. Firewalls are purchased in pairs. Nowhere in networking is something simple any longer.
With the advent of software, even the deployment of these devices is different. Automation and orchestration systems provide provisioning as the devices are brought online. Network Monitoring Systems ensure the devices are operating correctly via API call instead of relying on SNMP. Analytics and telemetry systems can pull statistics on the fly and create datasets that give you insight into all manner of network traffic. The intelligence built into the platform supporting the hardware is more apparent than ever before.
Networking is no longer about fast connectivity speed. Instead, networking is about stability. Providing a transport network that stays healthy instead of Continue reading
How Does Internet Work - We know what is networking
In case you wondered how to redistribute static routes into dynamic routing protocol you are at the right place. This is normally a basic thing to do, but I will let you know how to do it in different ways on different vendor devices so it might be interesting. We will go through few examples of normal static to OSPF redistribution and then see how it can be partially done with only part of static routes using route filters. I’ll do it on Cisco and Juniper devices so we can see what’s the difference. Cisco In Cisco CLI, redistribute static
Pilot users in Denver will soon be able to take Verizon's 5G network for a spin.
University lab will test products for conformance with new Ethernet specifications.
In this video, Tony Fortunato demonstrates how to take some basic latency measurements.
Imagine you were asked to migrate some of the workloads running in your data center into a public (or managed) cloud. These workloads still have to access the data residing in your data center – a typical hybrid cloud deployment.
Next thing you know you have to deal with your (C)ISO and his/her usual concerns as well as the variety of articles on tech sites stating that "security is the biggest challenge of cloud adoption".
