LAN Port 2 & LAN Port 3
If system detects more than one network card in the NAS server, this page will
automatically display LAN Port N tab to enable setup. "N" represents the id
number of the LAN port in the NAS server.
System administrator can add this LAN port to other LAN port(s), and there
are two ways to do so.
Trunking
The first way is called “Trunking” or "Link Aggregation", it simulates multiple
LAN ports belonging to the same team into a large-scale LAN port thus
multiplying the overall network bandwidth. These LAN ports share the same IP.
Should any LAN port fail, other LAN port(s) could still provide services. For
example, if a NAS server shares two 100 Mbps Fast Ethernet LAN cards,
through trunking the two cards into one, the bandwidth will expand to 200
Mbps. Should any of the network adapter(s) fail, other network adapter(s) in
the same team will continue to serve. Please note that “Trunking” is only
available when coupled with a switch supporting CISCO Fast EtherChannel
(FEC). “Trunking” is only allowed on network adapters with the same
bandwidth.
Fail-over
The other way is called “Fail-over”, it provides a redundancy solution. Should
any LAN port fail, other LAN port(s) in the same team would take over its job
and continue to provide services. Multiple network adapters with different
