Issues in TCP/IP Configuration

Consider the following guidelines when connecting a SnapServer to the network.
Cabling for Single-Subnet, Multihomed, or Network Bonding Configurations
• For a Single Subnet or Multihomed Configuration (Standalone) – Standalone
treats each port as a separate interface. In a single-subnet configuration, only the
primary port is connected to the switch. In a multihomed configuration, each port is
cabled to a different switch and the network connections lead to separate subnets.
supported by most network file protocols and can lead to unexpected results.
If you connect only one port, use the default primary port ( Ethernet 1 ). If you use Ethernet 2
or any other non-primary port, some services may not function properly.
• For a Network Bonding Configuration (Load Balancing, Failover, Switch Trunking,
or Link Aggregation) – Network bonding technology treats multiple ports as a single
channel, with the network using one IP address for the server.
NOTE: This network bonding configuration is only applicable to SnapServers with more than
• For load balancing, Switch Trunking, or Link Aggregation, these parts are

Setting Description
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:
Fixed The SnapServer may also be set to fixed speed/duplex setting:
10Mbps/half; 10Mbps/full; 100Mbps/half; 100Mbps/full.
NOTE:
Checked or By default, the primary Ethernet port is Ethernet 1 and it
Unchecked cannot be disabled. However, the Primary Interface can be
changed to a different Ethernet port by selecting the Ethernet
port you want as the Primary port and checking the
Interface box.
The Primary Interface is prioritized for various network
configuration parameters that apply to the server as a whole
(for example, DNS IP address, hostname, and default
gateway). In addition, the IP address of the Primary Interface is
preferred to identify the server for various services and
circumstances that require a single IP address.
CAUTION: Do not connect multiple Ethernet ports to the same network segment in
Standalone mode, except for iSCSI MPIO configurations. This configuration is not
one Ethernet port. To take advantage of network bonding, all ports in the bonded team
must be physically connected to the same network:
connected to the same switch on the same subnet.

Auto is the only allowable setting for a Gigabit port.

fixed setting, see "Changing from Auto to a Fixed Link
Setting" on page 3-7.
