Amazon Web Services (AWS) Kick Off Meetup Minutes
For those who couldn’t make Wednesday night’s call (or want a review), here is little of what we discussed.
WinSCP with Arista Switches
WinSCP is a popular tool used for quick uploading and downloading files between hosts. On a Linux or Mac, scp is a CLI tool already built in and can be invoked by using the scp command. However, unlike Linux and Mac, there is no native CLI for scp on Windows.
Arista VRF Fundamentals
This document will provide a summary over an Arista EOS switch and how an administrator can use Virtual Routing and Forwarding (VRFs) to achieve a desired solution. The number of VRFs varies per switch due to the amount of RAM and CPU on a switch. As of this writing, VRF scale are the following per model. Configuration of a VRF is fairly straightforward and all VRFs have their own separate forwarding tables. As with everything in EOS, all VRFs meet at SysDB. As these numbers may change in the future (as new features are added), please refer to the Release Notes and TOI documentation, These can be found on the Software Downloads page here.
Configure Linux or Microsoft DHCP Server for ZTP using CloudVision
One of the many features CloudVision offers along with Configuration management, image management, Telemetry, and Change Management are the Zero Touch Provisioning (ZTP) and Zero Touch Replacement (ZTR) features. Users can either use the preinstalled DHCP server on the CloudVIsion Portal platform or use any other DHCP server found in Linux or Microsoft Windows.
In this article, we will outline the steps required to get DHCP working on both the Linux and Microsoft platform as well as basic steps to provision a new switch, and replacement. All this can be done without the need for the blue console cable!
