Port Trunking

In the Port Trunking page, you can create multiple links between switches
that work as one virtual, aggregate link. Trunks can be defined for similar
port types only. For example, a 10/100 port cannot form a Port Trunk with a
gigabit port. For 10/100 ports, trunks can only be formed within the same
cluster. A cluster is a set of eight ports. Four trunks can be created at the
same time. Spanning Tree will treat trunked ports as a single virtual port.
NOTICE: Fast Ethernet trunks can only include ports from a single eight-port
cluster: Ports 1 to 8, ports 9 to 16, ports 17 to 24, ports 25 to 32, ports 33 to
40, or ports 41 to 48.
NOTICE: Built-in 10/100/1000BASE-T ports cannot be trunked with GBIC
ports.
