Downloading a Firmware Image
Enterasys C3 Configuration Guide 3-27
Parameters
Defaults
VT100 terminal mode is disabled by default.
Mode
Switch mode, read-write, when security profile = normal.
Switch mode, super-user, when security profile = C2.
Usage
VT100 mode is required to support automatic console session termination on removal of the serial
connection (vs. timeout). This mode requires that the attached console device be running VT100
terminal emulation.
In VT100 mode, the switch polls for device status (using the appropriate VT100 escape sequence)
to detect an attached device, which requires that the attached device be running VT100 terminal
emulation. At any time, if the switch fails to get a status reply, an existing console session is
terminated.
On receipt of the first polled status response, the login banner is displayed if it is configured.
Example
This example enables VT100 mode.
C3(su)->set console vt100 enable
Downloading a Firmware Image
You can upgrade the operational firmware in the Enterasys C3 switch without physically opening
the switch or being in the same location. There are two ways to download firmware to the switch:
• Via TFTP or SFTP download. This procedure uses a TFTP or SFTP server connected to the
network and downloads the firmware using the TFTP or SFTP protocol. For details on how to
perform a TFTP or SFTP download using the copy command, refer to “copy” on page 3-41.
For information on setting TFTP timeout and retry parameters, refer to “set tftp timeout” on
page 3-43 and “set tftp retry” on page 3-44.
• Via the serial (console) port. This procedure is an out-of-band operation that copies the
firmware through the serial port to the switch. It should be used in cases when you cannot
connect the switch to perform the in-band copy download procedure via TFTP. Serial console
download has been successfully tested with the following applications:
– HyperTerminal Copyright 1999
– Tera Term Pro Version 2.3
Any other terminal applications may work but are not explicitly supported.
The C3 switch allows you to download and store dual images. The backup image can be
downloaded and selected as the startup image by using the commands described in this section.
enable Enables VT100 terminal mode.
disable Disables VT100 terminal mode.
