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
Round-robin
*
Network packets are transmitted in sequential order from the first
available NIC slave through the last.
Active-backup
Only one NIC slave in the bond is active. A different slave becomes
active if and only if the active slave fails.
XOR
*
Transmits network packets based on [(source MAC address XOR’d
with destination MAC address) modulo NIC slave count]. This selects
the same NIC slave for each destination MAC address.
Broadcast
Transmits network packets on all slave network interfaces.
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 EtherChannel or other port trunking is required. Configure two LAN ports
on the switch for port trunking first.
**A separate intelligent switch that supports IEEE 802.3ad is required. Configure LACP in the switch first.
Configuring Port Trunking
1
Use an Ethernet cable to connect the hub LAN port and TeraStation LAN port 1.
Notes:
• If the TeraStation is being used as an iSCSI hard drive, disable iSCSI before changing network settings such as port
trunking. Navigate to
Drives
-
iSCSI
in Settings and move the iSCSI switch to the
position temporarily.
• 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.
