Configuring Port Trunks
Port trunks can be used to increase the bandwidth of a network
connection or to ensure fault recovery. You can configure up three trunk
connections (combining 2~4 ports into a fat pipe) between any two
ELS100-S24TX2M switches. However, before making any physical
connections between devices, use the Trunk Configuration menu to
specify the trunk on the devices at both ends. When using a port trunk,
note that:
•
The trunk ports must all be RJ-45 ports.
•
Ports can only be assigned to one trunk.
•
The ports in a trunk must belong to the same switch chip (see the
next page).
•
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 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.
