GNS3 for Mac


来自Mac App Store官方介绍

GNS3 is a graphical network simulator that allows simulation of complex networks.

To allow complete simulations, GNS3 is strongly linked with:

  • Dynamips, the core program that allows Cisco IOS emulation
  • Dynagen, a text-based front-end for Dynamips
  • Qemu, a generic and open source machine emulator and virtualizer
  • GNS3 is an excellent complementary tool to real labs for network engineers, administrators and people wanting to pass certifications such as CCNA, CCNP, CCIP, CCIE, JNCIA, JNCIS, JNCIE
  • Design of high quality and complex network topologies
  • Emulation of many Cisco IOS router platforms, IPS, PIX and ASA firewalls, JunOS
  • Simulation of simple Ethernet, ATM and Frame Relay switches
  • Connection of the simulated network to the real world!
  • Packet capture using Wireshark
  • Important notice: users have to provide their own IOS/IPS/PIX/ASA/JunOS to use with GNS3
