Ios

Everyone has different views on hardening IOS, and while I do not claim to be an expert, these are the practices that I commonly use when bringing up a new device.

Tired of setting up SPAN sessions? Need to do some packet analysis? Since IOS 12.4(20)T Cisco has made Embedded Packet Capture (EPC) available.

Greg Ferro of Etheralmind.com has started a petition asking Cisco to embrace those who pursue Cisco’s certifications a legal course of licensing without the cost of building a home made space shuttle.

Learning the particulars of Cisco IOS is one of the most valuable things a network engineer can do. These skills will be the basis of everything you do on the lab and on your network.

The Cisco IOS archive command is not only very useful in keeping configuration archives, but it can also be used to log commands entered into the router, along with their user name.

As a followup to my previous post on Regular Expression Basics, I wanted to give a few examples on using them on Cisco IOS.

This is one of those tricks you wish you learned about 10 years ago, but never did. You know how easy it is to mess up a nice looking access list.

How many times a day do you issue a show command from configuration mode ? If you’re anything like me, its enough to get annoying.

Ever accidentally set your config register to a random value that isn’t in the Cisco documentation? No? Neither have I, but one day I encountered someone on #cisco that had.

So, I’m sure these have been posted almost on every networking blog under the sun, but who knows, right?

As I started building this lab, I realized that I had to find a refresher course on the IOS naming conventions.
