IOS IPS: CCIE RS, CCIE SC. IOS IPS is fair game for the CCIE Security and CCIE R/S labs.
With IOS IPS now using v5 signatures, (just like the sensor appliance), the ability to setup up IOS is not as simple, but very important. The intention of this post is to provide a streamlined process to use as a jumpstart into IOS IPS. For full details, examples and explanations, please refer to our lab workbooks. Both RS and Security cover the topic. Lets get started! First, we need a place for IPS configuration files to call home. R6#mkdir ips Create directory filename [ips]?
Back Catalogue. GET VPN - Knowledge Base. GET (Group Encrypted Transport) VPN is a VPN technology which introduces the concept to eliminate point-to-point tunnels (site-to-site VPN) and associated overlay routing (DMVPN) since it relies on WAN routing.
It enables any-to-any VPN connectivity using a group IPSec security paradigm. In addition to IPSec, the following are the building blocks for GET VPN solution: 1. Group Domain Of Interpretation (GDOI) GDOI is a group key management protocol used to provide a set of IPSec keys to a group of IOS devices called Group Members (GM) that wish to communicate securely i.e. GDOI is a "Phase 2" protocol which is protected by "Phase 1 Security Association (SA)". RFC 3547 defines GDOI.

Darren's Blog. I know the title is quite a mouthful, but I did want to cover all the above in this post.
Daniel asked me to check a few things as I have ready access to real switches. You learn in your studies that layer 2 control packets are ‘special’ – Special in the way that traffic going over the trunk between 2 switches does not follow the standard practice. Let’s use wireshark to see exactly what is going on in a bunch of scenarios. It’ll also give me the opportunity to do a bit of testing with SPAN and RSPAN. Let’s use the basic topology: Let’s first set up a span session on the 3750.
Monitor session 1 source interface Gi1/0/9 monitor session 1 destination interface Gi1/0/24 The first thing I noticed when I plug in my laptop however is that Windows of course is very noisy. So now that I’ve booted up into NST and got Wireshark running, I hardly see anything at all happening between the 2 switches.

Tag: cisco (Atom feed) Cisco ASA Packet Capture Background The Cisco ASA can capture packets sent through the firewall; it can also capture packets that are denied by the firewall for various reasons.
The Problem For reasons I haven't fully understood, the ASA can be very picky about capture command syntax. R&S CCIE Home Lab: Cisco 3550 vs 3560. In my previous post on CCIE Lab Equipment, I talked a bit about alternatives for your hands on rack time.
I listed the pros and cons on why I decided to go with rack rentals versus buying. I certainly can't find fault with buying your own equipment if you have the funds, power, and space- so for those rats who are thinking about furnishing their own lab, I thought I'd do some digging on the 3550 versus the 3560. Captive Portal - HotSpot Authentication Gateway - Air Marshal. Captive Portal SystemWireless Hotspots * Wired Networks * Device AuthenticationNow avaliable for the Linux platform Captive portals provide a convenient method of controlling access to public and private networks leveraging existing web technologies.
Users simply "plug-in" open their favorite browser and follow on-screen prompting to logon to the network. The main benefits of this solution come from not requiring additional customer knowledge, software or special configuration. Clients are able to quickly and easily gain access to the network regardless of the type of device or operating system used. The Fiber Optic Association Tech Topics. The Fiber Optic Association - Tech Topics The FOA presents "Tech Topics" - a free resource for the fiber optic industry - schools, installers and contractors, and those interested in finding out more about the medium that has revolutionized communications.
