Port Trunking
In the Port Trunking page, you can create multiple links between switches that work as one virtual, aggregate link. You can create four trunks at a time, with
each trunk containing up to eight ports. Only ports of the same speed can belong to a single trunk: 10/100 Fast Ethernet ports and Gigabit Ethernet ports
cannot be in the same trunk.
NOTICE: Fast Ethernet trunks can only include ports from a single eight-port cluster: Ports 1 to 8, ports 9 to 16, or ports 17 to 24.
NOTICE: Built-in 10/100/1000BASE-T ports cannot be trunked with GBIC ports.
To add a port to a trunk, click the toggle button below the port number until the correct trunk number appears.
NOTICE: All ports participating in a trunk must be operating in Full Duplex mode.
NOTICE: All ports participating in a trunk should have the same VLAN and CoS settings.
