SmartSwitch Router User Reference Manual 5
Chapter 1: Introduction
The Enable mode command prompt consists of the SSR name followed by the pound
sign(#):
To exit Enable mode and return to User mode, either type exit and press Return, or press
Ctrl+Z.
Configure Mode
Configure mode provides the capabilities to configure all features and functions on the
SSR. These include router configuration, access control lists and spanning tree. To enter
Configure mode, enter the command config from Enable mode.
Note:
As mentioned previously, up to four Telnet sessions can be run simultaneously on
the SSR. All four sessions can be in Configure mode at the same time, so you
should consider limiting access to the SSR to authorized users.
The Configure mode command prompt consists of the SSR name followed by (config) and
a pound sign (#):
To exit Configure mode and return to Enable mode, either type exit and press Return, or
press Ctrl+Z.
Boot PROM Mode
If your SSR does not find a valid system image on the external PCMCIA flash, the system
might enter programmable read-only memory (PROM) mode. You should then reboot the
SSR (enter the command reboot at the boot PROM prompt) to restart the system. If the
system fails to reboot successfully, please call Cabletron Systems Technical Support to
resolve the problem.
For information on how to upgrade the boot PROM software and boot using the
upgraded image, see the SmartSwitch Router Getting Started Guide.
Getting Help with CLI Commands
Interactive help is available from CLI by entering the question mark (?) character at any
time. The help is context-sensitive; the help provided is based on where in the command
