	# Disable Ethernet 1/0/10 from learning MAC addresses dynamically, and add a
	static MAC address entry. So that port Ethernet 1/0/10 can only send packets
	destined for the NMS, and other hosts cannot communicate through this port.

Precautions	■ When you add a MAC address entry, the port specified by the interface
	keyword must belong to the VLAN specified by the vlan keyword in the
	command. Otherwise, the entry will not be added.
	■ If the VLAN specified by the vlan keyword is a dynamic VLAN, adding a static
	MAC address entry will make the VLAN become a static VLAN.
