Failover This mode uses the first Ethernet port as the primary network
interface and the second Ethernet port is held in reserve as the
backup interface. Redundant network interfaces ensure that an
active port is available at all times. If the primary port
(Ethernet1) fails due to a hardware or cable problem, the
secondary port (Ethernet2) assumes its network identity. The
two ports should be connected to different switches (though
this is not required).
Note
Failover mode does not provide switch fault tolerance.
Switch
Trunking This mode groups multiple physical Ethernet links to create
one logical interface. Provides high fault tolerance and fast
performance between switches, routers, and servers.
Link
Aggregation
(802.3ad) Like Switch Trunking, this mode groups multiple physical
Ethernet interfaces to create one logical interface, and
provides high fault tolerance and fast performance between
switches, routers, and servers. Uses Link Aggregation Control
Protocol (LACP), to autonegotiate trunk settings.
Enable
Ethernet Checked By default, both Ethernet ports are enabled, whether they are
used or not.
Unchecked If the Ethernet2 port is not being used, it can be disabled by
selecting the port and unchecking the Enable Ethernet
checkbox. However, a bonded Ethernet port cannot be
disabled, nor can a disabled Ethernet port be placed in bonded
mode.
Note
Ethernet1 must always be enabled. GuardianOS will not
allow you to disable it.
Speed/
duplex Auto The default setting of Auto enables automatic negotiation of
the speed and duplex settings based on the physical port
connection to a switch. The speed setting establishes the rate
of transmission and reception of data. The duplex setting
allows the Ethernet port to transmit and receive network
packets simultaneously.
Note
Auto is the only allowable setting for a Gigabit port.
Fixed The Snap Server may also be set to fixed speed/duplex
setting: 10Mbps/half; 10Mbps/full; 100Mbps/half; 100Mbps/full
Note
To prevent connectivity problems when changing to a
fixed setting, see “Changing from Auto to a Fixed Setting” on
page 24.
