Whether we are talking about EtherChannels or PortChannels, we are talking about the same technology. That technology is a way to allow you to treat multiple physical links as one link to Spanning-Tree, and you can also do some load-balancing on them. There are two types of port channels. They can be a layer 2 […]

Spanning-Tree is a layer 2 loop detection mechanism for a switched network. There are several spanning-tree standards Cisco also has two proprietary types of spanning tree; One of the most important pieces of a spanning tree is electing a root switch. You can leave the election up to chance or “rig” the election how you

I remember all the insanely complicated things in my studies but forget the little stupid things. This is going to be a quick compile of my CCIE notes for VLAN’s A VLAN is a Layer 2 technology that shrinks the broadcast domain in your inter-network. If there were no VLANs, depending on the size of

Well, I am back.. I just finished typing up my notes for CCIE R&S, and I have a lot to say. It turned out to be 210 pages, so I have a hard copy next to me, and there will be some more reading and blogging happening soon :). On a better note, I scheduled
Many people don’t understand a private VLAN and when to use it. I will try to explain what it is and how to implement it properly. A private VLAN can block host-to-host communication at layer 2, only allowing them to talk to their default gateway. I say essentially out of their broadcast domain because a
VLAN Trunking Protocol, or VTP, is a Cisco proprietary protocol allowing you to pass VLAN information between switches. There are three modes that VTP can be configured in VTP Server mode is the default, and it will send VTP updates to other VTP servers or client devices over a trunk or port channel. VTP Client

Now that we have the basic configuration out of the way and the device is manageable, the next step is configuring the ACE to load-balance for a site. Our task will be to configure the following; The configuration for the above is; I am trying to get my hands on one of our spare 6500’s

The configuration we will look at is an ACE module that goes into a 6500 series chassis. It would help if you did some prep work on the 6500 before configuring the ACE. The first step is to create the VLANs; in this example, we will use VLAN 4 and VLAN 67. The next step

Wow, it’s been a long time since I’ve posted. I have been knee-deep in studying for my CCIE R&S, learning my new environment at my new job, and being a father to my newborn son. I will start the New Year with something new I learned at my job: how a Cisco ACE works and

I just passed 642-611 and am now a CCIP. I will still post the MPLS blogs in my downtime while waiting for my books for CCIE Security.
