makes examining and understanding the configuration easier.
Getting the Default or Current Property Value
The period "." character before a tab can be used to automatically fill in the default value for an
object property in an Add command. For example:
Device:/> add LogReceiver LogReceiverSyslog log_example
Address=example_ip
LogSeverity=.
This will fill in the default value for LogSeverity:
Device:/> add LogReceiverSyslog example
Address=example_ip
LogSeverity=Emergency,Alert,Critical,Error,Warning,Notice,Info
This severity list can then be edited with the back arrow and backspace keys. A default value is
not always available. For example, the Action of an IP rule has no default.
This same sequence can be used to get the current property value in a Set command. For
example:
Device:/> set LogReceiver LogReceiverSyslog log_example Address=.
This will display the current value for the Address property.
Appending Property Values
Another usage of the period character before a tab is to automatically fill in the current value of
an object property in a command line. This is very useful when there is a need to append a new
value to a list of pre-existing values.
For example, the following unfinished command may have been typed:
Device:/> set Address IP4Address If1_ip Address=
If a period "." followed by a tab is now entered, cOS Core displays the current value for Address. If
that value were the IPv4 list 10.6.58.10,192.168.2.1 then the unfinished command line will
automatically become:
Device:/> set Address IPAddress If1_ip Address=10.6.58.10,192.168.2.1
The displayed values can then be added to or changed with the backspace and back arrow keys
before completing the command.
Object Categories
It has been mentioned that objects are grouped by type, such as IP4Address. Types themselves
are grouped by category. The type IP4Address belongs to the category Address. The main use of
categories is in tab completion when searching for the right object type to use.
If a command such as add is entered and then the tab key is pressed, cOS Core displays all the
available categories. By choosing a category and then pressing tab again all the object types for
that category is displayed. Using categories means that the user has a simple way to specify what
kind of object they are trying to specify and a manageable number of options are displayed after
pressing tab.
