interface, menu options are to enable the interface, and to set “IP address”, “sub-
net mask”, and “MTU”.
At least one network interface (“bond0”, “eth0”, “eth1”) must be
Enabled. If all net-
work interfaces are set to
Disabled, attempting to save changes will give an error
message.
The menu item set (
Enabled, “IP address”, “subnet mask”, “MTU”) will be
repeated for each interface. Settings below for “IP address”, “subnet mask” and
“MTU” will be shown only if the corresponding Ethernet interface is
Enabled.
If more than one interface is enabled, the network addresses must be disjoint (i.e.,
the combination of “IP address” and “subnet mask” must resolve to separate inter-
faces). The following examples include valid and invalid configurations to further
explain this requirement:
eth0 192.168.1.1/255.255.255.0
eth1 192.168.2.1/255.255.255.0
This is a
valid combination. IP addresses looking like 192.168.1.X are routed to “eth0”, and addresses look-
ing like 192.168.2.X are routed to “eth1”.
eth0 192.168.1.1/255.255.0.0
eth1 137.157.1.8/255.255.0.0
This is a
valid combination. IP addresses looking like 192.168.X.X are routed to “eth0”, and
addresses looking like 137.157.
X.X are routed to “eth1”.
eth0 192.168.1.1/255.255.255.0
eth1 192.168.1.1/255.255.255.0
This is an
invalid combination. Both interfaces have the same network parameters.
eth0 192.168.1.1/255.255.255.0
eth1 192.168.1.2/255.255.255.0
This is an
invalid combination. The miSAN-V-Series cannot route outgoing IP requests without
additional configuration information.
eth0 192.168.1.1/255.255.0.0
eth1 192.168.2.1/255.255.255.0
This is an
invalid combination. Because of the different subnet masks, the network addresses
overlap, so the miSAN-V-Series cannot route IP requests without additional configuration
information.
