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.
Caution Do not connect multiple Ethernet ports to the same network segment in
Standalone mode, except for iSCSI MPIO configurations. This configuration is
not supported by most network file protocols and can lead to unexpected results.
Caution If you connect only one port, use the primary port (Ethernet1). If you use
Ethernet2, 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 one ethernet port.
To take advantage of network bonding, all ports in the bonded team must be
physically connected to the same network:
• For load balancing, Switch Trunking, or Link Aggregation, connected to the
same switch on the same subnet; or
• For failover, connected to a different switch on the same subnet (in case one
switch fails).
• 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.
Modified Indicates whether configuration for one or more interfaces has been changed
and needs to be applied to take effect:
• Yes—One or more parameters for the interface have been modified.
• No—No parameters for the interface have been modified.
