Python3 Network Programming – Enabling SSHv2 and Disabling Telnet using Automation, and how to secure your network by enabling SSHv2 and disabling Telnet (very carefully)!

It is time to ditch the SSH and move onto Netmiko that would actually be used in most production networks, which involves a bit more than "enable ssh" if you have not turned it on before / turned off telnet, but I will demo it here of course via Automation! I am still continuing on … Continue reading Python3 Network Programming – Enabling SSHv2 and Disabling Telnet using Automation, and how to secure your network by enabling SSHv2 and disabling Telnet (very carefully)!

TSHOOT – Management Plane vs Control Plane vs Data Plane, MPP (Management Plane Protection) review for exam day!

This graphic that I created to help myself understand CEF Hardware Packet Switching is also very similar to the Management Plane vs Control Plane vs Data (Forwarding) plane. Management Protocols run at the Management Plane (hence the name Mgmt Plane) is where Management Protocols such as SSH / Telnet / SNMP / HTTP / HTTPS … Continue reading TSHOOT – Management Plane vs Control Plane vs Data Plane, MPP (Management Plane Protection) review for exam day!

TSHOOT – Using CLI Tools Part 2 – Ping, Extended Ping, Traceroute, Telnet, SNMP, Netflow, EEM (Embedded Event Mgr), FTP reviewed!

I was going to demonstrate some concepts in packet tracer to make writing out explanations a bit quicker, but I need to speed up my grind a bit here, so I'm just going to foot to the floor these next few explanation before I take a break from blogging to really put my nose to … Continue reading TSHOOT – Using CLI Tools Part 2 – Ping, Extended Ping, Traceroute, Telnet, SNMP, Netflow, EEM (Embedded Event Mgr), FTP reviewed!

Telnet vs SSH – How to secure your Switch Management (Transport) protocols, explained and labbed!

The point of this post is to discuss how to secure Switch management in the network, by not only using SSH (as it encrypts traffic!), but also how to disable Telnet sessions AND even create our old friend an Access-Class map to act as our Management ACL! I will get right to it, by first … Continue reading Telnet vs SSH – How to secure your Switch Management (Transport) protocols, explained and labbed!
