Cisco TFTP


Cisco Trivial File Transfer Protocol (TFTP) is a Windows NT service that builds and serves files consistent with the TFTP protocol. TFTP is a simplified version of the FTP protocol. Cisco TFTP serves both Embedded Component Executable and configuration (.cnf) files.

A configuration file is a list of Cisco CallManagers to which devices (telephones and gateways) make connections. When a device boots, the component queries a Dynamic Host Configuration Protocol (DHCP) server for its network configuration information. The DHCP server responds with an IP address for the device, a subnet mask, a default gateway, a Domain Name System (DNS) server, and a TFTP server name or address.

The device requests a .cnf file from the TFTP server. The .cnf file contains a list of Cisco CallManagers and the TCP port to which the device connects to those Cisco CallManagers.

If the Cisco CallManager's name is received, the device resolves the name using Domain Name System (DNS) and a Cisco CallManager connection is opened. If neither an IP address or name is received, the default server name is used.

For more detailed TFTP information, refer to the following sections:

Understanding DHCP and TFTP, page 6-2

Understanding How Devices Identify the TFTP Server, page 6-3

Use the following procedures to insert and delete TFTP service from a server, to configure and delete Command Line Parameters, and to configure and delete TFTP Trace Parameters:

Inserting Cisco TFTP Service on a Server

This section describes how to insert Cisco TFTP service on a server.

Before You Begin

The following prerequisite must be met before proceeding with the steps. See the "Server" section on page 8-1.

Servers must be configured

Procedure


Step 1 Open Cisco CallManager Administration.

Step 2 Click Service > TFTP.

Step 3 Select a server on which to insert Cisco TFTP service from the drop-down menu and click Insert. (Servers listed on the left side of the page have already been configured with TFTP service.) The page refreshes, showing the server you selected.

Step 4 Click Insert.

The page refreshes again and the server you selected should now be configured with Cisco TFTP service.


Tips Click New if you want to insert Cisco TFTP on another server. This takes you back to the first Cisco TFTP Configuration page.



Note You only need to configure Cisco TFTP service on one server in a network, unless you want to share loading of service.

Configuring Cisco TFTP Command Line Parameters

This section describes how to configure Cisco TFTP command line parameters.

Before You Begin

The following prerequisite must be met before proceeding with the steps. See the "Server" section on page 8-1.

Servers must be configured

Read the "Understanding Service Parameters" section for more information on service parameters.

Procedure


Step 1 Open Cisco CallManager Administration.

Step 2 Click Service > TFTP.

Step 3 Select the server on which you want to configure command line parameters from either the drop-down menu, or the list of servers on the left side of the page. The page refreshes.

Step 4 Click Command Line Parameters if it is not already selected.


Caution Some changes to service parameters may cause system failure. We recommend you do not make any changes to service parameters unless you fully understand the feature that you are changing, or unless the changes are specified by the Cisco Technical Assistance Center (TAC). Refer to the "Understanding Service Parameters" section for more information. You will probably never need to add parameters unless directed by the Cisco TAC.

Step 5 Enter the name of the parameter you want to configure on this server in the Param field.

Step 6 Enter the type of the parameter in the Type field, or choose a type from the drop-down menu.


Note The drop-down menu contains parameter types that have already been configured.


Step 7 Enter a value for the parameter in the Value field.

Step 8 Click Update. The page refreshes and your new service parameter appears in the Configured Service Parameters list at the bottom of the page.

Step 9 Repeat Steps 1 through 8 to add additional service parameters.


Note If you would rather use the Cisco CallManager default service parameters, click Default. A message displays stating that you are about to permanently delete any previous settings and replace them with the default settings. Click OK if you wish to continue, or Cancel to keep the current settings.
