The Static MAC Filter destination port mask. When setting this value, the system will ignore configuration for ports not between the first and last valid ports. Configuration of any port numbers between this range that are not valid ports return a failure message, but will still apply configuration for valid ports. To obtain port numbers from interface numbers, use the objects hm2AgentPortDot1dBasePort and hm2AgentPortIfIndex in the hm2AgentPortConfigTable table. Configuring destination port mask for a unicast MAC filter is not supported on some platforms.
