Sample Session
To create the sample confi guration s hown in Figur e 1 on a BN router with an Ethernet link module
in slot 2, enter the following BCC commands. Notice how each BCC prompt contains the BCC
identifier of the object just configured.
Command Comment
box# ethernet slot 2 connector 1 Configures ethernet 2/1 using a fully specified
interface location.
ethernet/2/1# ip 11.23.13.14/8 Configures ip/11.23.13.14/255.0.0.0 using a
decimal mask value. The BCC automatically
configures the global ip object when y ou conf igure
the first ip interface on the box.
ip/11.23.13.14/255.0.0.0# rip Configures RIP on ip/11.23.13.14. No parameter
values are required.
rip/11.23.13.14# back Moves back one level closer to box or root level.
ip/11.23.13.14/255.0.0.0# back 2 Moves back two levels to box level.

• Use the "-recursive" option to check for dependencies
related to the current context and all of its subcontexts.

Command Shortcuts
• To recall any command from the history list, press the up arrow (or [Control]-p) or the
down arrow (or [Control]-n).
• Enter the first few letters of any command and press [Tab] to complete your partial entry.
The BCC automatically completes the string for any command for which it finds a unique
match in the current context. If you want to complete the string
[Enter] instead of [Tab]. If the BCC cannot complete the string based on your partial entry,
your available choices or an error message displays. You can also use this feature to
simplify the entry of object names/IDs and parameter names/values.
• To reduce typing, use commands such as lso to display existing objects and then copy
and paste their
