panic [<string>] [confirm=<string>]

This causes the FB2500 to crash, causing a panic event with a specified message. You need to specify confirm=yes for the command to work. This can be useful to test fallback scenarios by simulating a fatal error. Note that panic crash logs are emailed to the FireBrick support by default, so please use a meaningful string. e.g. panic "testing fallback" confirm=yes

reboot [<unsignedInt>] [hard] [confirm=<string>]

A reboot is a more controlled shutdown and restart, unlike the panic command. The first argument is a block number (see show flash contents) and forces reboot to run a specific software stored in flash. Normally the reboot will run the latest valid code. The hard option forces the reboot to clear the Ethernet ports and other hardware so takes a couple of seconds. You must specify confirm=yes for this to work.

set command screen width <unsignedInt>

This allows you to set the screen width.

start command session <IPAddr> [port=<unsignedShort>] [table=<routetable>]

This allows a reverse telnet connection to be made. A TCP connection is made to the IP address (and port) where a user can login. This can be useful where a firewall policy prevents incoming access to allow someone to have access from outside, e.g. the FireBrick support team.

show command sessions

The FB2500 can have multiple telnet connections at the same time. This lists all of the current connections.

kill command session <IPAddr>

You can kill a command session by IP address. This is useful if you know you have left a telnet connected from somewhere else. Telnet sessions usually have a timeout, but this can be overridden in the configuration for each user.

show flash contents

Lists the content of flash memory - this includes various files such as software releases, configuration, and so on. Multiple copies are usually stored allowing you to delete a later version if needed, and roll-back to an older version.

delete config <unsignedInt> [confirm=<string>]
delete data <unsignedInt> [confirm=<string>]
delete image <unsignedInt> [confirm=<string>]

Delete a block from flash memory. This cannot be undone. You have to specify the correct type of block, and specify confirm=yes for the command to work.

show boot log [<unsignedInt>]

Show log of recent boots. You can specify the number of bytes of recent log to show.

show flash log [<unsignedInt>]

The logging system can log to flash for a permanent record. This is done automatically for some system events and when booting. You can specify the number of bytes of recent log to show..
