Upgrading The Switch Image; Auto Installation - Motorola RFS Series Reference Manual

2-4 Motorola RF Switch System Reference

2.3 Upgrading the Switch Image

The switch ships with a factory installed firmware image with the full feature functionality described in this
System Reference Guide. However, Motorola periodically releases switch firmware that includes
enhancements or resolutions to known issues. Verify your current switch firmware version with the latest
version available from the Motorola Web site before determining if your system requires an upgrade.

2.4 Auto Installation

The switch auto install function can be configured manually or using a DHCP server. When configuring auto
installation using DHCP, the server requires the definition of a vendor class and four sub-options under option
43 namely:
• Option 186 - defines the tftp/ftp server and ftp username, password information
• Option 187 - defines the firmware path and file name
• Option 188 - defines the config path and file name
• Option 190 - defines the cluster config path and file name.
The individual features (config, cluster-config and image) can be enabled separately using the CLI, SNMP or
Web UI. If a feature is disabled, it is skipped when auto install is triggered.
For manual configuration (where the URLs for the configuration and image files are not supplied by DHCP),
the URLs can be specified using the CLI, SNMP or Applet. Use the CLI to define the expected firmware image
version. If the image version is not specified, the switch will derive it from the header of the firmware image
file.
Configuration files are tracked by their MD5 checksum. Configuration files are tracked by their contents. If a
file is renamed its contents remain the same and the file will not be reloaded.
The requested image file version (if any) is checked against the current version before any attempt is made
to load it. If the requested version is the same as the running version, no action is taken. If the image file
version (embedded in the file header) does not match the expected version, no further action is taken. If the
version has not been specified, the image file header is compared to the local version. If they are the same,
no action is taken.
NOTE: Once the system has been operating for ten minutes, Auto Install is disabled,
though it may still be reconfigured. This is to prevent the system from attempting to re-
install each time a DHCP lease is renewed.
Configuring Auto Install via the CLI
There are three compulsory and four optional configuration parameters.
The compulsory parameters are:
• configuration upgrade enable
• cluster configuration upgrade enable
• image upgrade enable
Optional (only for the static case):
• configuration file URL
• cluster configuration file URL
