Port Trunk Configuration
Port trunks can be used to increase the bandwidth of a network
connection or to ensure fault recovery. You can configure up to four
trunk connections (combining 2 to 4 ports into a fat pipe) between any
two AT-8324SX switches. However, before making any physical
connections between devices, us the Trunk Configuration menu to
specify the trunk on the devices at both ends. When using a port trunk,
note that:
❑ The ports used in a trunk must all be of the same media type (RJ-
45, 100 Mbps fiber, 1000 Mbps fiber). The ports that can be
assigned to the same trunk have certain other restrictions as
described later in this section.
❑ Ports can only be assigned to one trunk.
❑ The ports in the trunk must belong to the same switch chip (as
explained later in this section.
❑ The ports at both ends of a connection must be configured /as
trunk ports.
❑ The ports at both ends of a trunk must be configured in an
identical manner, including speed, duplex mode, and VLAN
assignments.
❑ The communication mode must be configured identically at both
ends of the trunk.
❑ None of the ports in a trunk can be configured as a mirror source
port or a mirror target port.
❑ All the ports in a trunk have to be treated as a whole when moved
from/to added, or deleted from a VLAN.
❑ The Spanning Tree Algorithm will treat all the ports in a trunk as a
whole.
❑ Enable the trunk prior to connecting any cable between the
switches to avoid creating a loop.
❑ Disconnect all trunk port cables or disable the trunk ports before
removing a port trunk to avoid creating a loop.
