The IOS Simulator integrated with the Network Simulator, allows you to simulate Cisco routers and Cisco switches supporting Cisco IOS Software. It offers a realistic simulation for any management application that uses IOS.  The IOS Simulator fully supports SNMPv1, v2c, v3 and TFTP. The simulated Cisco routers and switches can be accessed using CLI.

Enterprises as well as management application developers can simulate a complete Cisco network environment. The IOS simulator supports the following modes - user, privilegedEXEC, global configuration, Interface configuration mode, Router mode (BGP, OSPG, RIP, EIGRP),  Vlan mode and config-if mode.

You can login and logout of the IOS simulator, get into and out of different modes, configure cdp, access-list, rmon alarms and events, set passwords, ip addresses, clock rates, hostname,  enable/disable SNMP trap service, configure SNMP community, contact, location etc., specify MTU value for the network interface node, configure BGP, OSPF, RIP and vlan for a specific router, ping devices, display startup and running config and many other functions.
