The BCC is case-sensitive. Enter all commands using lowercase letters.
To recall any command from the history list, press the up arrow (or Control-p) or down
arrow (or Control-n).
To display online Help, enter the help commands after either the bcc> prompt (indicating
operations mode) or the box# prompt (indicating configuration mode), as Table 1 shows.
Configuring the Versalar 15000
When you enter configuration commands, they immediately modify the configuration.
The Versalar™15000 uses a hierarchical tree configuration model similar to the DOS
hierarchy of directories and files. The configuration tree for the Versalar 15000 contains:
•Objects:An Ethernet interface or a protocol is an object (a physical or logical entity
you can configure).
•Parameters:Characteristics of an object; slot and connector are parameters of the
object mct3. Parameters 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. Figure 1 shows the BCC
commands you enter to create a sample portion of the tree.

The mct3 object stands for multichannel T3.(Figure 1 does not show the configurable
objects under the ppp object.)
The following example shows how to configure these services:
box# ethernet slot 9 connector 1
ethernet/9/1# ip 11.23.13.14/8
ip/11.23.13.14/255.0.0.0# rip
rip/11.23.13.14# box
box# mct3 slot 1 connector 1
mct3/1/1# t3
t3/1/1# ppp
ppp/1/1#
The BCC creates a unique identifier for each object that you add to the tree. The ID
consists typically of the object name plus any parameter values required for configuration,
such as in the example above, ethernet/9/1.Theslash(/) characters are part of the ID.
When the BCC is in configuration mode, you can go to any configured object by entering
its unique ID after any prompt, regardless of your current position in the configuration
tree. For example, enter ip/11.23.13.14/255.0.0.0 to go to the IP interface configured on
ethernet/9/1.
As you navigate between levels of the tree, the BCC prompt changes to show the unique
ID of the object configured at your current location. (Refer to the previous configuration
example to see how the prompt changes.)
The lso command displays the unique identifiers of branch objects configured
immediately below your current location in the tree. If you do not know the unique ID of
an object, enter lso -r after the box# prompt to display the configuration object IDs
recursively.
When you add IP to an interface, the BCC accepts the subnet 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 contiguous bits reserved for the network portion
of the IP interface address). For example, enter any of the following commands to create
an object with the unique ID ip/11.23.13.14/255.0.0.0:
ip address 11.23.13.14 mask 255.0.0.0
ip address 11.23.13.14 mask 8
ip 11.23.13.14/255.0.0.0
ip 11.23.13.14/8
When you use BCC to create a configuration, the BCC prompts you for parameter values
that it cannot automatically assign. To change a parameter value, you enter the name of the
parameter, a space, and the new value.
Table 2 shows each help configuration task, the associated command, and examples.
