Port Trunking
Two Ethernet cables can be used to establish two separate communication routes, providing LAN port redundancy
and improving communication reliability. The use of two Ethernet cables enables access to the TeraStation even if
one of the cables is disconnected.
The port trunking modes that can be set in the TeraStation are shown below.
Trunking Mode Characteristics
Active-backup
Only one NIC slave in the bond is active. A different slave becomes
active if and only if the active slave fails.
Dynamic link aggregation
*
Creates aggregation groups that share the network speed and duplex
settings. Utilizes all slave network interfaces in the active aggregator
group according to the 802.3ad specification.
TLB
The outgoing network packet traffic is distributed according to the
current load (relative to the speed) on each network interface slave.
* A separate intelligent switch that supports IEEE 802.3ad is required. Configure LACP in the switch first.
If the TeraStation is being used as an iSCSI drive, disable iSCSI before changing network settings such as port
trunking. Navigate to
Storage - iSCSI in Settings and move the iSCSI switch to the off position temporarily.
1
Use an Ethernet cable to connect the hub LAN port and TeraStation LAN port 1.
Notes:
• Do not connect the second Ethernet cable to the TeraStation yet.
• If using an intelligent switch, configure the LAN ports on the switch first, before connecting to the
TeraStation.
