GNS3 is a graphical network simulator that allows you to design complex network topologies and to launch simulations on them.
To allow complete simulations, GNS3 is strongly linked with :
- Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems.
- Dynagen, a text-based front-end for Dynamips.
- Pemu, a PIX emulator.
GNS3 is a excellent complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA, CCNP, CCIP or CCIE certifications.
It can also be used to experiment features of Cisco IOS or to check configurations that need to be deployed later on real routers. This project is an open source product that may be used on multiple platforms, including Windows, Linux, and MacOS X.
- Designing high quality complex network topologies.
- Emulating Cisco routers and PIX firewalls.
- Simulating simple Ethernet, ATM and Frame Relay switches.
- Load and save in Dynagen’s INI-like format.
- Image export (JPEG, PNG, BMP and XPM).

The Performance barriers created by the WAN:
Bandwidth constraints keep applications from performing well.
Too much data and too small of a pipe causes congestion, packet loss, and backpressure.

I use 3750 for 16 PCs and 12 IP Phone 7960G. PC client still work but I can’t use or activate PoE on my IP Phone anymore. I try to give command = “power inline consumption <miliwatts range 4000 – 15400>” but still failed.
does anyone know whats the problem??
the answer here on sadikhov forum..
Cisco Unified Communications Manager (CUCM), formerly Cisco Unified CallManager and Cisco CallManager (CCM), is a software based IP call agent platform sold by Cisco Systems. Cisco renamed the product to Unified Communications Manager. Version 6 was supposed to merge all features of the Linux appliance (SIP support and licensing requirements) between the Linux platform and Windows version. The released version of Unified Communications Manager will not support the Windows platform.
This version added an intercom feature between endpoints, and integrated Mobility Manager (single number reach to multiple destinations, IP Phone, Cell Phone, etc).
