This category is a summary of the time I have put into CCIE R&S track preparation. Many CCIE’s talk about how they studied 8 hours a day for an entire year, or they put 300 hours into practice labs, etc. That may be; I may end up having to put the same kind of time […]
This probably ends up being a 2-parter. It’s 6pm already, my dinner is coming soon, and I’m a little fried from the day at work. We’ll see how far I get. Here goes. Spanning-tree protocol (STP) is the language switches speak to be sure that there are no topology loops in the layer 2 network. […]
The next chapter I have to do the write-up on is Spanning Tree. Ugh. I already read it, and it was a bit of a beast. Lots of stuff I knew, but spanning-tree is one of those topics that I never quite learned as well as I should have. It was a handy thing to […]
VLAN – a virtual LAN. Ports defined to be a common broadcast domain. Can span multiple switches through the use of trunks. broadcast domain – devices that are on the same ethernet area. When a broadcast is sent to this area, everyone in the area gets it. Typically, one subnet per broadcast domain.
Good review of all the basics here: VLAN’s, starring DTP, 802.1q, ISL, tags, private VLAN’s, and more. Not a terribly long chapter, but good fundamentals to know. Definition of a VLAN – a group of ports that can span multiple devices, but are still a part of the same broadcast domain. Usually, you have a […]
I’m planning on building a lab with 2 6513’s, 2 3550’s, 4 3750’s, at least 1 3845 (I think I can put my hands on one), and 2 or 3 or 4 2600’s I have available. That’s not the hugest priority for me today as I have to get through the written exam. But…I’m going […]
I also read chapters 2 and 3 in the OECG book this week (VLAN’s and spanning-tree), but I don’t have the energy to do the write-ups on them like I did for chapter 1 right now. Maybe a bit later. I think I’ll go balance the checkbook and pay some bills for now.
