Two Ethernet cables can be used to establish two separate communication routes for providing redundancy of LAN
ports and improving communication reliability. The use of two Ethernet cables enables access to the TeraStation even if
one of the cables is disconnected.
Note:
A separate hub or intelligent switch is required to use the port trunking function.
The port trunking modes that can be set in the TeraStation are shown below.
[Disabled]:
Port trunking is not used.
[Round-robin] (*1):
A round-robin policy is set for providing fault tolerance and load balancing.
[Active-backup]:
An active-backup policy is set for providing fault tolerance.
[XOR] (*1):
An XOR (exclusive-or) policy is set for providing fault tolerance and load balancing.
[Broadcast]:
A broadcast policy is set for providing fault tolerance.
[Dynamic link aggregation] (*2):
An IEEE 802.3ad dynamic link aggregation policy is set.
[TLB]:
An adaptive transmit load balancing (TLB) policy is set for providing fault tolerance and load balancing.
*1 A separate intelligent switch that supports EtherChannel or other port trunking is required. Two LAN ports of the intelligent
switch must be set for port trunking beforehand. For details on the setting procedure, see the manual supplied
with the intelligent switch.
*2 A separate intelligent switch that supports IEEE 802.3ad is required. The LACP (Link Aggregation Control Protocol)
function of the intelligent switch must be enabled beforehand. For details on the setting procedure, see the manual supplied
with the intelligent switch.
