Cayman 3220-H User’s Guide

autoboot sequence tries to load an image from download sources in 
the following order:

1.

If flash is enabled, start an image from the Cayman 3220-H code 
flash memory, using the configured image number; else

2.

If ip is enabled, load an image via IP TFTP using the configured 
IP server, IP gateway, netmask and filename; else

3.

If bootp is enabled, load an image from a BOOTP server   on your 
IP network.

 The Cayman 3220-H alternates steps 2 and 3 at 10-second intervals 
for the number of attempts specified in the 

 argument, 

trying each download source that is enabled.

bootp { on | off }

The 

bootp

 command enables/disables BOOTP downloading. If 

BOOTP is enabled, the Cayman 3220-H broadcasts a BOOTP request. 
It will use the response as the source of its IP address, the server and 
gateway IP addresses, and the name of the file to TFTP-download. 
The EPROM recognizes the CMU and RFC-1048 “vendor extensions” 
to the basic BOOTP format, and uses the netmask and gateway 
address provided by BOOTP if available.

file file_name

The 

file

 command specifies the name of the EPROM software file 

the Cayman 3220-H should download.

flash { on | off }

The 

flash

 command enables/disables flash booting. If the specified 

boot image in flash memory is valid, it will be used as the source of 
the image to run when the box autoboots or when the command 
boot flash is given.

flash on

 enables downloading from flash.
