Parameter groups facilitate in defining format boundaries which can be used within one or more node types. For example you can define the Snmp_sysname variable's size/format and which user role is required to edit this variable.
Enter the desired name for the new parameter group and click the Add button to create it.
Enter the desired name for the new parameter group and click the Duplicate button to create it.
A variable of the type CHAR with a edit level of Operator will be created by default
To remove a parameter group variable select the variable in question and click the trashcan icon a prompt will show up asking if you are sure, click the Yes button to delete the parameter group variable
Select the parameter group variable you want to edit and make the desired changes.
After making changes to your parameter group variable commit them by clicking the Apply button.
Most custom attribute types are quite self-explanatory: CHAR is a string of text, NUM is a number, IPv4 is an IPv4 address, etc. However the MENU type needs a bit of explanation. This is for if you want to have a dropdown of various options.
A menu doesn't have a size, but a format, which can have four possible options: Str_value, Num_value, Str_value&Num_value and Num_value&Str_value. When you select a menu custom attribute a grid with profiles appears. This grid corresponds to the Par_group_profiles table in the netYCE database. A profile consists out of a number, a string and a default. Only one profile in a par group menu can be set, and this will be the standard value whenever it's created. When you try to set a second value as default, the older default value will lose its default status.
What you see in the actual frontend is based on the format:
Note that if the format is set to Str_value or Str_value&Num_value, it is not possible to have profiles within the same menu that have the same string value. Likewise, if the format is set to Num_value or Num_value&Str_value you can not have duplicate numerical values.
