Parameters

hostname

Enter the main hostname that identifies the SBC. Entries must follow either the Hostname (or FQDN) Format or the IP Address Format.

description

Describe the SBC. Entries must follow the Text Format

location

Enter the physical location of the SBC used for informational purposes. Entries must follow the Text Format.
