TL-SG2216WEB/TL-SG2224WEB Web Smart Gigabit Switch Family User's Guide 4.3.2 Aging Time and Dynamic Address Table A dynamic MAC address table is maintained inside the switch. A MAC address is the physical address of a network device; it is six-bytes long and should be hole in a subnet. A network device can be identified by its MAC address. A dynamic address table entry contains two items: MAC address and its corresponding switch port. The dynamic address table is volatile. The dynamic address entry begins to age once it is added; it will be purged if it isn't renewed in a specified time length, which is defined as aging time. The aging time ranges from 0 to 630 seconds for this switch family. The default value is 300 seconds. Dynamic address table entry won't age if 0 is set. The aging time precision is 15 seconds. 4.3.3 Static MAC Address Table A static MAC address table entry contains a MAC address and its corresponding switch port. All the packets taking that MAC address as their destination will be forwarded to the corresponding switch port. The static MAC address won't age, which differs from the dynamic MAC address. The static MAC address table entry is always valid before it is deleted. Suppose an entry, whose MAC address is 000AEB000001 and corresponding port number is 1, is added to the static MAC address table. All the packets routing to the address of 000AEB000001 egress for the switch port 1. This static entry obliges the device of 000AEB000001 to be connected to port 1; otherwise, that device cannot be accessed. Static MAC addresses are free of 15
