Custom-Options

These scenarios test custom DHCP options and vendor-encapsulated-options. Custom options allow administrators to define non-standard DHCP options for vendor-specific configurations or custom network requirements.

Custom options can use: - Hex data: Raw hexadecimal values - ASCII data: Text strings - IP addresses: IPv4 address lists

Vendor-encapsulated-options (Option 43) allow vendor-specific data to be sent to clients, commonly used for IP phones, wireless controllers, and other specialized network equipment. Verification is done via the client extended-detail command to confirm the options are received and stored in monitoring-db.

Custom Options

Description

Verify custom DHCP options and vendor-encapsulated-options via extended-detail.
