Some people hate it, some people love it. It's the Cisco proprietary VLAN Trunking Protocol (VTP) which in short means that Cisco switches can exchange VLAN configuration, instead of manually configuring each switch with the same VLANs. I also suggest if you don't know what a VLAN is check out the post Creating VLANs Let's get right into understanding VTP.
If you ever wanted to set up a network manually, you will quickly find how much overhead is required to get PCs, printers, and other network equipment. That's where dynamic routing protocols come into play although they are helpful I strongly urge you to understand static routing first. (See the post Configure Static Routing) So for today's post let's get the foundation of understanding dynamic routing protocols. By definition a routing protocol is a set of messages, rules and algorithms used by routers for the overall purpose of learning routes to other networks not physically connected to it.
Plugging Cisco routers together and hoping they work out of the box is not something you should hope for. A router can learn about networks in two ways, manually from configured static routers which we will talk about today and dynamic routing protocols which will talk about on Wednesday. Let's get started!
The wonderful AAA which in the Cisco world means, Authentication, Authorization, and Accounting but what does that really mean? In today's post that's what we are going to be talking about. What is AAA and what are the benefits of using it along with what is it?
So for today's post let's learn how to configure a site-to-site VPN on a router using the Cisco SDM (Security Device Manger). The Cisco SDM is a Web-based device management tool a GUI for Cisco routers this can simplify router deployments and cut ownership costs. (See the post Configuring SDM) Let's start configuring a site-to-site VPN with SDM!
Awhile back I talked about the differences between IPS and IDS. (See the post Cisco IDS vs. IPS ) So for today's post let's learn how to configure an IPS (Intrusion Prevention System) on a router using the Cisco SDM (Security Device Manger). The Cisco SDM is a Web-based device management tool a GUI for Cisco routers this can simplify router deployments and cut ownership costs. ( See the post Configure Cisco SDM) Let's start configuring an IPS with SDM!
Last month I talked about the fundamentals for understanding zone based firewalls (See the post Understanding Zone Based Firewalls). So for today's post I want to go ahead and talk about configuring the zone based firewalls but with the Cisco SDM (Security Device Manger). The Cisco SDM is a Web-based device management tool a GUI for Cisco routers this can simplify router deployments and reduce ownership costs. (See the post Configure Cisco SDM) Instead of talking about what is zone based firewalls lets jump into the configuration of them.
Today we will be going over the steps that are required to set up the Cisco SDM (Security Device Manger) The Cisco SDM is a Web-based device management tool a GUI for Cisco routers this can simplify router deployments and cut ownership costs. SDM is fairly easy to set up but you still need at least some experience in the router command-line to get SDM working.
Today's post is going to be talking about troubleshooting and where to start the troubleshooting process. Yes there is an actual process that every technician should be aware of. You can also use this troubleshooting process at home, you may not know how to fix it but at least you know where the issue is and find someone who can. Before we begin if you haven't seen yet, let me introduce to you the troubleshooting process:
Yesterday was kind of exciting at least for me when I got an e-mail in the morning about Cisco Learning Labs. Studying for the CCNA, CCNP or CCIE is in itself changeling, but getting that hands-on experience is a another problem! When money is short that last thing you want to do is spend it on routers and switches, and most of them on eBay are used and the risk of failing devices makes it a scary choice.
