Port Trunk 
Port trunking is the combination of several ports or network cables to expand the 
connection speed beyond the limits of any  one single port or network cable. Link 
Aggregation Control Protocol (L ACP), which is a protocol running on layer 2, provides 
a standardized means in accordance with  IEEE 802.3ad to bundle several physical 
ports together to form a single logical cha nnel. All the ports within the...
