There are three available LAN interfaces in NAS-5400. Thus you can team these ports in Trunking
mode or Fail-over mode.
“
Trunking
”
is also known as "Link Aggregation"; it simulates two LAN ports belonging to the same
team into one large-scale LAN port thus multiplying the overall network bandwidth. These LAN
ports share the same IP. Should any LAN port fail, the other LAN port could still provide services.
Trunking mode can only applied to two ports with the same bandwidth. So you can only trunk LAN
port 1 and LAN port 2 together.
For example, if a NAS server trunks two 100 Mbps LAN ports, the bandwidth will expand to 200
Mbps. Should any of the LAN port fail, the other one in the same team will continue to serve.
Note:
“
Trunking
”
is only available when coupled with a switch supporting CISCO Fast
EtherChannel (FEC), and is only allowed on LAN ports with the same bandwidth.
The
“
Fail-over
”
mode provides a redundancy solution. Should any LAN port fail, the other port in
the same team would take over its job and continue to provide services. Multiple network adapters
with different bandwidths can be teamed as
“
Fail-over
”
. In this case the network adapter with
larger bandwidth will be used as the master network adapter. When the master network adapter
fails, the other network adapter will take over the service.
