TFTP

With TFTP you can use the writeflash command to install new firmware. To send a new firmware version which, for example, is in the 'LC_1000U.130' file, to a router with the IP address 194.162.200.17, you would enter the following command under Windows NT for example:

tftp -i 194.162.200.17 put lc_1000u.130 writeflash

This command sends the corresponding file to the router using the writeflash parameter. Binary file transfer must be set for TFTP. However, many systems have the ASCII format preset. This example for Windows NT shows you how to achieve this by using the '-i' parameter.

The device is booted up following a successful firmware upload and this activates the new firmware switch directly. If an error occurs during the upload (write error in the flash ROM, TFTP transmission error or similar) the device also boots and FirmSafe activates the previous firmware. The configuration remains in operation.

It will only be possible to configure the device locally, i.e. via the outband interface, if it is switched off during TFTP upload. The device will expect a firmware upload via the serial port when it is switched back on.

You should therefore be sure to carry out a firmware upload only when you have a secure (stable) connection.

With TFTP, other configuration commands can also be executed. The syntax is best demonstrated with the following examples:

Ktftp 10.0.0.1 get readconfig file1 : Reads the configuration from the device with the address 10.0.0.1 and saves it as file1 in the current directory

Ktftp 10.0.0.1 put file1 writeconfig : Writes the configuration from file1 to the device with the address 10.0.0.1

Ktftp 10.0.0.1 get dir/status/verb file2 : Saves the current connection information in file2

Configuration using SNMP

General

The Simple Network Management Protocol (SNMP V.1 as specified in RFC 1157) allows monitoring and configuration of the devices on a network from a single central instance. This instance is commonly termed the“Manager” while the devices become“Agents”. The structure permitted for SNMP information exchange is relatively simple. A manager can access all SNMP-capable devices and services (agents) on the network. The access rights are controlled via“Communities”.
