Chapter 55 Configuring a VoIP Network

Using SmartPorts

•In the above example, $DATAVLAN and $AUXVLAN are variables and are substituted with appropriate values when the macro is applied to a port.

•After the macro is defined, it is stored in NVRAM.

Modifying Existing User-Defined Macros

To modify an existing user-defined macro, use the set macro name name command. When modifying a macro, the new definition replaces the old definition but the new definition is not automatically applied to all the ports on which it was previously applied. You need to explicitly apply the modified macro. An example is as follows:

Console> (enable) set macro name fileserver

Enter macro commands one per line. End with the character '@'. cmd1

cmd2

@

Console> (enable)

The macro named “fileserver” can be overwritten by creating a macro with the same name and new definitions. An example is as follows:

Console> (enable) set macro name fileserver

Enter macro commands one per line. End with the character '@'. cmd2

cmd3

@

Warning: The macro fileserver has been modified; Do you want to modify (y/n) y Console> (enable)

Defining Variables

To define a variable, use the set macro variable name_of_variable variable_of_value [mod/port] command. You can define the variable on a per-port basis or a global basis. When a macro is applied to a port, the variables are replaced with the values that you have defined. The maximum length of a variable name is 16 characters. A macro definition can use multiple variables in a single line. Per-port variables are defined on a per-port basis. Individual ports can be configured with different values by defining variables with different values for different ports. If a variable definition does not have port information, then it is treated as a global variable. The global variable definition is used if the per-port variable is not defined. An example is as follows:

Console> (enable) set macro variable $DATAVLAN 3 3/2

Variable DATAVLAN successfully created

Console> (enable) set macro variable $DATAVLAN 5 3/3

Console> (enable) set macro variable $AUXVLAN 4 3/2

Variable AUXVLAN successfully created

Console> (enable)

If a port is not specified in the variable definition, the variable is considered a global variable. An example is as follows:

Console> (enable) set macro variable $CDPVER v2

Variable CDPVER successfully created

Console> (enable)

Console> (enable) set macro variable $DATAVLAN 77

Console> (enable)
