Chapter 30: File Transfer
464
The IPADDRESS parameter is the IP address of the TFTP server, and
the FILENAME parameter is the name of the new management
software file to be downloaded to the switch from the TFTP server. The
filename must include the “.img” extension and cannot contain spaces.
In this example of the command, the IP address of the TFTP server is
149.11.124.5 and the filename of the new management software to be
downloaded from the server is “at-9000_sw.img”:
awplus# copy tftp flash 149.11.124.5 AT-9000_sw.img
After receiving the entire file from the TFTP server, the switch
compares the version numbers of the new image file and its current
management software. If the new image file has an earlier or the same
version number as the current management software, the switch
cancels the update procedure. If the new image file has a newer
version number, the switch writes the file into flash memory and then
resets.
5. Wait for the switch to write the new management software to flash
memory.
6. To resume managing the switch, start a new management session
after the switch has reset.
7. To confirm the new management software on the switch, use the
SHOW SYSTEM command in the User Exec mode or the SHOW
SWITCH command in the Privileged Exec mode to check the version
number of the management software on the switch.
Downloading
Files to the
Switch with
TFTP
To use TFTP to download boot configuration files or CA certificates to the
switch:
1. Store the file on the TFTP server on your network.
2. Start a local management session or a remote Telnet or SSH
management session on the switch.
3. The command for downloading files to the switch with TFTP is the
COPY TFTP FLASH command in the Privileged Exec mode. Here is
the format of the command:
copy tftp flash
ipaddress filename.exe
The IPADDRESS parameter is the IP address of the TFTP server. The
FILENAME parameter is the name of the file you want to download
from the TFTP server to the switch. The filename extension must be
“.cfg” for boot configuration files and “.pem” for CA certificates. The
filename cannot contain spaces.
