Baud Rate
You may set the management port baud rate either from the CLI (via SNMP) or
through the boot time debug menu.
Once a given baud rate has been set, that baud rate will continue to be used by
both the boot and application code, until you set a different value.
The baud rate will remain unchanged through all warm resets, cold resets, and
power cycles.
If the current baud rate setting has been forgotten, follow this procedure to force
the baud rate to a known value:
1
Power off the unit.
2
Remove the flash card.
3
Power on the unit (with the flash card removed).
4
With the power on, insert the flash card.
