4.5  MAC Address Table 

This 6-byte ID is called the MAC (Media Access Control) Ad-
dress. Every Ethernet data packet includes both source and 
destination addresses. 

These Fast Ethernet Switch models can automatically learn 
and store up to 8K MAC addresses. The MAC address table is 
volatile: it disappears when the switch is powered off or reset. 

Note:

 When the network needs reconfiguration, we 

recommend turning off the power first. After all 
nodes have been moved, power on the switch to 
rebuild the internal MAC address table.
