disconnect

To close an active console port or Telnet session, use the disconnect command.

disconnect {ip_addr | console}

Syntax Description

ip_addr	IP address or IP alias.
console	Denotes an active console port.

Defaults

This command has no default settings.

Command Types

Switch command.

Command Modes

Privileged.

Usage Guidelines

If multiple sessions from the same IP address exist, the disconnect command checks if the current process is also from the same IP address. If it is not, all Telnet sessions from the specified IP address are disconnected. If it is, all sessions, other than the current session, are disconnected. The system prompts whether or not to disconnect the current Telnet session. You can answer n and remain connected or answer y and be disconnected.

Examples

This example shows how to close a Telnet session to host 198.134.214.4:

Console> (enable) disconnect 198.134.214.4

Telnet session from 198.134.214.4 disconnected. (1)

Console> (enable)

This example shows how to close the current console session:

Console> (enable) disconnect console

Console session disconnected.

download

To copy a software image from a specified host to the Flash memory of a designated module, use the download command.

download host file [mod] [rcp]

download serial

download vmps

download boot flash_device:filename mod_num

download epld file [mod [force]]

Syntax Description

host	Name or IP address of host.
file	Name of file to be downloaded.
mod	(Optional) Number of the module to receive the downloaded image.
rcp	(Optional) Specifies rcp as the file transfer method.
serial	Specifies download through a serial port.
vmps	Downloads VMPS.
boot	Downloads an image to the boot ROM of a module.
flash_device:filename	Name of the software image to be downloaded.
mod_num	Number of the module to receive the downloaded image.
epld	Updates the module's Erasable Programmable Logic Device (EPLD) image file.
file	Name of the EPLD image file.
force	(Optional) Updates the existing EPLD image file on the module with the new EPLD image regardless of the version of the existing image.

Defaults

If a module number is not specified, the image is downloaded to all modules for which the image is valid.

Command Types

Switch command.

Command Modes

Privileged.

Usage Guidelines

Catalyst 6500 series switches download new code to the processors using Kermit serial download through the EIA/TIA-232 console port.

The download command downloads code to the module Flash memory. Catalyst 6500 series switch software rejects an image if it is not a valid image for the module.

The download serial command uses Kermit through the serial EIA/TIA-232 console port. The download serial command is not allowed from a Telnet session.

Before you can execute the download vmps command successfully, you must use the set vmps downloadserver command to configure the IP address of the TFTP server and the name of the VMPS configuration file on that server. If the IP address of the TFTP server is not configured, the download vmps command reports an error. If the configuration filename is not configured, the download vmps command uses the default filename vmps-config-database.1.

After a successful download, the new VMPS information replaces any existing information. If there are not enough resources to build the new configuration database, the VMPS is made inactive.

If you specify the module number, the download goes to the specified module, but the download will fail if the module is of a different type than is indicated by the download header. If you do not specify the module number, the download goes to all modules of that type.

---

Caution After starting the serial download using Kermit, do not attempt to abort the serial download by pressing Ctrl-C. Pressing Ctrl-C interrupts the download process and could leave the switch in a problematic state. If the switch is in a problematic state as a result of pressing Ctrl-C, reboot the switch.

---

If you enter the download epld file command without specifying a module, the new EPLD image is downloaded to all compatible modules where the new EPLD image version is greater than the existing version on the module. If the download epld file mod command is used with the force keyword, the existing EPLD image on a module is upgraded with the new EPLD image regardless of the version level of the existing image.

---

Caution If you remove the module while the EPLD image is updating, the module might not come back online.
