Hello Marcio,
You could achieve this using a group and group rules.
- Administration->Groups->Add group
- Name and create the group.
- Select the group and click the Rules tab->Add Rule
- Select Interfaces from the dropdown
- Click Add Condition
- Fill out the condition you would like to match the interfaces.
-- For example, Interface Description matches regex .*\[GSM\].*
-- You may need to adjust the Regular Expression (regex) to match your needs.
- Click Preview Results to test the rules.
If they match what you are looking for click Save and Run Rules to immediately populate the group.
Select the group when running the dashboard.
