Port Aggregation
Port Aggregation (Port Trunk) is used to increase the bandwidth of a switch-to-switch
connection and backup. This switch provides 8 port aggregation groups, which consist
of 2 ports and create bandwidth up to 4Gbps per group at full duplex mode. Check the
box of Aggregation Group in the Status Enable column and press "Apply" then the
selected Aggregation Group is activated.
However, before making connections between switches, pay attention to
· The ports at both ends of a Port Aggregation connection must be configured as
Aggregation Ports
· The ports at both ends of a Port Aggregation connection must have the same port
properties, including Speed, Duplex mode
· All the ports of a Port Aggregation must be treated as an integer when added
to/deleted from a VLAN
· Spanning Tree Algorithm (STA) cannot coexist with Port Aggregation
· Before connecting cables between switches, enable the Pot Aggregation to avoid
looping
· Before disabling Port Aggregation, remove the connecting cables between switches
to avoid looping
· Both two slide-in slots should use the identical modules (two coppers/two fibers)
otherwise the Port Aggregation connection is invalid
