Wireshark Troubleshooting

Wireshark Troubleshooting Videos

There is a lot of great stuff on YouTube. By the way I find it is even more excellent to watch YouTube with my Roku. But I digress. There are a lot of Laura Chappell videos about network troubleshooting with Wireshark. Much of it is in the Laura's Lab Kit distribution at: http://llk11-2014.s3.amazonaws.com/lauraslabkit11b.zip Here is one example of a great video that demonstrates Wireshark features for troubleshooting: https://www.youtube.com/watch?v=70dRbN4Y2no&feature=player_embedded&list=UUfdeux1c9erKgFAwSpTlICA Links to others and my notes from each are available in this document: Wireshark Notes

Cisco Daisy Chained Consoles

Cisco Daisy Chain Console

Daisy Chaining from one device to another can be a great backup method to access network devices without having to have a modem (or more than one.) So, if I want to be able to get to the console on a core switch at a site after having a local contact boot it up, I could enable this by connecting a cisco rollover cable from my router to the switch. This would allow me to connect to the router over the WAN side interface and then connect to the switch from the router.

Cable to buy

Need a “rollover cable.” This is the product:
