Host Devices

This document gives a brief overview of the Windows2000, Linux and Solaris host devices configured in the device tree of the Network Designer. The devices support SNMP and TFTP .   Linux / Solaris devices support Telnet in addition to SNMP, TFTP and FTP.

Device Types

The following host devices are supported.

• Windows2000

• SunSolaris

• RedHatLinux

Device Configuration

The following MIBs are supported in the host devices.

• RFC-1213 MIB

• HOST-RESOURCES.MIB

• IF-MIB

• IP-FORWARD.MIB

• LMMIB2.MIB

• UCD-SNMP-MIB (only for RedHatLinux and SunSolaris)

• sun.mib (only for SunSolaris)

Scripts Configured

The following scripts are configured in the Behaviour Configuration wizard.

linkStatusTraps.py

If ifAdminStatus of a interface with instance .1 is set to up(1)/down(2), ifOperStatus of the corresponding interface is updated and a Linkup/Link down Trap is sent with ifOperStatus as varbinds.

ipForwardType.py

If the ipforwardType in the IP-FORWARD.MIB is set to invalid (2), then the value of .1.3.6.1.2.1.4.24.1 (ipForwardNumber)  is decremented by 1.

To learn about the steps involved in defining your own scripts, refer to the topic Configuring Network Behavior.

Using the Host Simulation

• Start the Network Designer from <SimulatorHome>/bin directory.

• You will find the Host devices added in the device tree under the group node Host.

• Create a network using the host device. Refer to Creating and Configuring a Network.

• Start the device by selecting the right-click option Start Device. The device will be started at default SNMP port 8001 and TFTP port 69.
