Description:
This user function tests whether the MAC address represented by MAC_FIELDindicates that a certain manufacturer produced the network adapter with that MAC address.

Syntax:
@manuf(MAC_FIELD, MANUFACTURER_ID)

Arguments:

MAC_FIELD A protocol field ID in the form <PROTOCOL_ID>:<FIELD_ID>. The protocol field represented by that ID must be of type MAC Address.

MANUFACTURER_ID A three byte MAC address manufacturer's ID prefix. This argument may be represented as:

an unformatted, decimal numeric string (e.g., 123456)

a formatted, hexidecimal numeric string (e.g., 12:A7:8A)

a symbolic name alias, representing a numeric value (e.g., CISCO)

Returns:
True if the MAC address data at the specified protocol node indicates the specified manufacturer, else false.

Example:
The following example tests whether the Token Ring destination MAC address specified by the ID TOK:DLC.DA is an IBM-assigned MAC address.

@manuf(TOK:DLC.DA, IBM)
