Monitoring Frame Relay - 0 views
-
Several commands are used frequently to check the status of your interfaces and PVCs once you have Frame Relay encapsulation set up and running. To list them, use the show frame ? command, as seen here
The show frame-relay lmi Command - 0 views
-
The show frame-relay lmi command will give you the LMI traffic statistics exchanged between the local router and the Frame Relay switch.
The show frame pvc Command - 0 views
-
The show frame pvc command will present you with a list of all configured PVCs and DLCI numbers. It provides the status of each PVC connection and traffic statistics too.
The show interface Command - 0 views
-
You can use the show interface command to check for LMI traffic. The show interface command displays information about the encapsulation, as well as layer 2 and layer 3 information.
The show frame map Command - 0 views
-
The show frame map command displays the Network layer-to-DLCI mappings. Here's how that looks
The debug frame lmi Command - 0 views

The debug frame lmi command will show output on the router consoles by default (as with any debug command).
Troubleshooting Frame Relay Networks - 0 views
-
Troubleshooting Frame Relay networks isn't any harder than troubleshooting any other type of network as long as you know what to look for, which is what I'm going to cover now.
Configuring PPP with Authentication Using SDM - 0 views
-
First, I'm going to configure the serial WAN link between the Corp router and the R3 router using PPP with Authentication.
Configuring PPPoE with SDM - 0 views
-
To configure PPPoE with SDM, we'll first need a router connecting to a DSL modem, and then we'll need to configure the interface as a client just as we did earlier. I'll make it painless by using SDM on my 871W router.
Configuring Frame Relay with SDM - 0 views
-
Now that our serial connection between the Corp and R3 routers is up and running with PPP and you know how to configure PPPoE, I want to show you how easy it is to set up Frame Relay using SDM.
Virtual Private Networks - 0 views
-
I'd be pretty willing to bet you've heard the term VPN more than once before. Maybe you even know what one is, but just in case, a virtual private network (VPN) allows the creation of private networks across the Internet, enabling privacy and tunneling of non-TCP/IP protocols.
Introduction to Cisco IOS IPSec - 0 views
-
Simply put, IPSec is an industry-wide standard suite of protocols and algorithms that allows for secure data transmission over an IP-based network that functions at the layer 3 network layer of the OSI model.
Security Protocols - 0 views
-
"The two primary security protocols used by IPSec are Authentication Header (AH) and Encapsulating Security Payload (ESP)."
Configuring VPNs/IPSec Using the SDM - 0 views
-
There are a lot of different ways to configure VPNs on your router. What I am going to do here is add a straight VPN connection between the Corp and R3 routers.

Configuring Quality of Service (QoS) across Our VPN Tunnel - 0 views
-
QoS is actually more secure, cost effective, even faster in today's networking environment! This is why I'm going to show you how to configure QoS on our VPN serial link-a great place to configure QoS in a production network, by the way.
