Chapter 1 | Initial Switch Configuration
Automatic Installation of Operation Code and Configuration Settings
– 61 –
◆ Note that the switch itself does not distinguish between upper and lower-case
file names, and only checks to see if the file stored on the server is more recent
than the current runtime image.
◆ If two operation code image files are already stored on the switch’s file system,
then the non-startup image is deleted before the upgrade image is transferred.
◆ The automatic upgrade process will take place in the background without
impeding normal operations (data switching, etc.) of the switch.
◆ During the automatic search and transfer process, the administrator cannot
transfer or update another operation code image, configuration file, public key,
or HTTPS certificate (i.e., no other concurrent file management operations are
possible).
◆ The upgrade operation code image is set as the startup image after it has been
successfully written to the file system.
◆ The switch will send an SNMP trap and make a log entry upon all upgrade
successes and failures.
◆ The switch will immediately restart after the upgrade file is successfully written
to the file system and set as the startup image.
To enable automatic upgrade, enter the following commands:
1. Specify the TFTP or FTP server to check for new operation code.
■
When specifying a TFTP server, the following syntax must be used, where
filedir indicates the path to the directory containing the new image:
tftp://192.168.0.1[/filedir]/
■
When specifying an FTP server, the following syntax must be used, where
filedir indicates the path to the directory containing the new image:
ftp://[username[:password@]]192.168.0.1[/filedir]/
If the user name is omitted, “anonymous” will be used for the connection. If
the password is omitted a null string (“”) will be used for the connection.
If no user name nor password is required for the connection, then the “@”
character cannot be used in the path name.
This shows how to specify a TFTP server where new code is stored.
