BCC™ Quick Reference (AN/BN Routers)
The BCC Configuration Tree
The BCC uses a hierarchical tree configuration model similar to the DOS hierarchy of directories and files. The BCC
configuration tree for a network device contains:
•
Objects --
Physical or logical entities you can configure. An Ethernet interface or a protocol is an object.
•
Parameters
--Attributes or properties of an object;
slot
and
connector
are attributes of the object
ethernet
.
Parameters also have
values
; for example,
slot 4
is a parameter-value pair.
Starting at the root level, you build a BCC configuration by adding objects to the tree. Every object occupies a specific
level, or
context
, within the tree, as shown below.
The boldface labels in the figure are the actual BCC commands used to create this configuration.
Configuration Tips
• Start a BCC configuration session by logging in to the Technician Interface as
Manager
. Next, enter
bcc
and
wait for the
bcc>
prompt. Enter
config
at the
bcc>
prompt and wait for the
box#
configuration prompt.
• Configure interfaces first, then add protocols. When you enter BCC configuration commands, you
immediately modify device behavior.
• As you navigate between levels of the configuration tree, the BCC prompt changes to show your current
location. The BCC indicates the current location by displaying the unique identifier of the configured object at
your current location, for example:
ip/192.168.3.4/255.255.255.0
.
• To access any object, type the path to that object. For example, to access RIP on one of the Ethernet
interfaces configured above, type
eth 2/1;ip 1.2.3.4/255.0.0.0;rip.
(Note that the BCC interprets each
semicolon [ ; ] as if you had pressed the Return key to start a new command line.)
• Whenever you add IP to an interface, the BCC accepts the mask value in either dotted-decimal notation (for
example, 255.255.255.0) or in standard decimal notation (for example, 24, representing the number of bits
reserved for the network portion of the IP interface address). For example:
ip address 11.23.13.14 mask 255.0.0.0
(or)
ip 11.23.13.14/255.0.0.0
(or)
ip address 11.23.13.14 mask 8
(or)
ip 11.23.13.14/8
Entering any of these commands creates an object with the unique identifier
ip/11.23.13.14/255.0.0.0
• The BCC responds with helpful prompts whenever you leave out information required to configure an object.
• To move back one level closer to root (box#) level, type
back
; to move back to root level, type
box.
• To exit from BCC configuration mode, type
exit
. To exit the BCC and return to the Technician Interface prompt,
type
exit
again. To log out of the router, type
logout
. If you exit and then reenter the BCC without rebooting,
configuration changes that you made during the last BCC session are still in effect.
• Enter all commands using lowercase letters.
• You can abbreviate object names or parameter names; however, the abbreviations must be unique. For
example, two objects,
fddi
and
ftp
, exist at the root level of the BCC configuration tree for a BN router. To let
the BCC know which of these objects you want to configure, you must minimally enter either
fd
or
ft
at the
box#
prompt.
• The BCC does not recognize abbreviated system commands (commands available in any BCC mode); for
example, the BCC will not recognize
sh
as
show
.

Common BCC Commands
Common BCC Operations
The BCC indicates when configuration parameters have values that are REQUIRED (you must supply a value). Other
parameters have DERIVED or DEFAULT values supplied by the system.
