# 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.

■

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.
