Required and Optional Attributes
You must specify a value for
•Any [
<attribute-name> <value>
] pair classified as “REQUIRED” in the help-
text, or enclosed in {braces} in the syntax description for a command.
•Any [
<attribute-name> <value>
] pair that has a default value of “None”
All other (“optional”) attributes of an object assume a system default value.
Specifying Multiple Attribute-Value Pairs
Within a specific context, you can
• Enter an object name, plus one [
<attribute-name> <value>
] pair per command
line until you configure all the attributes that need to be changed for that
object. For example:
bcc> ethernet 2/1
ethernet/2/1> ip address 1.2.3.4
ip/1.2.3.4> mask 255.255.255.0
ip/1.2.3.4> ospf area 2.3.4.54
ospf/1.2.3.4> hello-interval 5
ospf/1.2.3.4>
• Enter an object name, plus a series of
<attribute-name> <value>
pairs (each
pair separated by a space) until you configure all the attributes that need to be
changed for that object. For example:
bcc> ethernet 2/1
ethernet/2/1> ip address 1.2.3.4 mask 255.255.255.0
ip/1/2/3/4> ospf area 2.3.4.54 hello-interval 5
ospf/1.2.3.4>
Note: The BCC frequently uses required attributes to make up the unique
instance identifier for a configured object. You cannot change the value of any
attribute that makes up the instance identifier for an object. To change these
attributes, you must delete the object, then add it back into the device
configuration with new values.
