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
