How can configure cisco 2950 switch

If you do not configure the DHCP server with the lease options described earlier, it replies to client requests with only those parameters that are configured. If the IP address and subnet mask are not in the reply, the switch is not configured. Unavailability of other lease options does not affect autoconfiguration. For more information, see the "Configuring the Relay Device" section.

If you did not specify the configuration filename, the TFTP server, or if the configuration file could not be downloaded, the switch attempts to download a configuration file by using various combinations of filenames and TFTP server addresses.

The files include the specified configuration filename if any and these files: network-config, cisconet. For the switch to successfully download a configuration file, the TFTP server must contain one or more configuration files in its base directory.

The files can include these files:. The preferred solution is to configure the DHCP server with all the required information. The TFTP server contains the configuration files for the switch. If it is on a different LAN, the switch must be able to access it through a router. You must configure a relay device when a switch sends broadcast packets that need to be responded to by a host on a different LAN.

You must configure this relay device to forward received broadcast packets on an interface to the destination host. If the relay device is a Cisco router, enable IP routing ip routing global configuration command , and configure helper addresses by using the ip helper-address interface configuration command.

For example, in Figure , configure the router interfaces as follows:. Figure Relay Device Used in Autoconfiguration. Depending on the availability of the IP address and the configuration filename in the DHCP reserved lease, the switch obtains its configuration information in these ways:. The switch sends a unicast message to the TFTP server to retrieve the named configuration file from the base directory of the server, and upon receipt, completes its boot-up process.

The switch sends a broadcast message to a TFTP server to retrieve the named configuration file from the base directory of the server, and upon receipt, completes its boot-up process. The configuration filename is not provided two-file read method. The switch sends a unicast message to the TFTP server to retrieve the network-confg or cisconet. If the network-confg file cannot be read, the switch reads the cisconet.

The default configuration file contains the host names-to-IP-address mapping for the switch. The switch fills its host table with the information in the file and obtains its host name. If the host name is not found in the file, the switch uses the host name in the DHCP reply. If the host name is not specified in the DHCP reply, the switch uses the default Switch as its host name.

After obtaining its host name from the default configuration file or the DHCP reply, the switch reads the configuration file that has the same name as its host name hostname -confg or hostname. If the cisconet. If the switch cannot read the network-confg, cisconet. If the switch cannot read the router-confg file, it reads the ciscortr.
