Port Trunking - D-Link DES-3624i User Manual

Port Trunking

Port trunking is used to combine a number of ports together to make a single high-bandwidth data pipeline. The
participating parts are called members of a trunk group, with one port designated as the anchor of the group. Since all
members of the trunk group must be configured to operate in the same manner, all settings changes made to the anchor
port are applied to all members of the trunk group. Thus, when configuring the ports in a trunk group, you only need to
configure the anchor port.
The Switch supports 3 trunk groups, which may include from 2 to 8 switch ports each, except for the third trunk group
which consists of the 2 ports of the Slot 1, 100BASE-TX or 100BASE-FX front-panel module. The anchor port for the first
group is preset as port 5, the anchor port for the second group is port 13 and the anchor port for the third group is the first
port (1x) on the 2-port module.
