Parameter
Description
Network Mode
Supports 4 modes.
Multi-address

Multiple network cards can have different segments and realize
multi-segment access, which is suitable for the scenario with high
requirement of network reliability. For example, when configuring hot
standby, you need to use network card 2 to set standby heartbeat IP;
also it can be adopted in the scheme with ISCSI expansion storage.
The planning of network port is shown as follows:
Network port 1 is used as service communication and network port 2
is reserved; network port 3 and 4 are used as ISCSI storage.
Fault tolerance

Multiple network cards use one IP address. Generally only one
network card is working, and it will automatically enable another
normal network card to guarantee network smoothness when working
network card fails.
Load balancing

Multiple network cards use one IP address. These network cards work
together, share network load and provide network loading capacity
which exceeds single network card bandwidth. When one network
card is abnormal, it will distribute load to other available cards again
and provide network reliability.
Link Aggregation

Through network card binding and peripheral communication, the
bound network card takes part in the work and shares the network
load, realizing one network card forwarding stream bigger than 1K.
For example, 2 IP bound, the other 2 have different IP, then the server
owns 3 IP, the bound IP bandwidth is 2K while other 2 is 1K. Link
aggregation can be realized only when link aggregation is supported
by directly-connected switch.
Select Port
Supports default network port configuration. The platform default port
is Network Port 1 (when ten gigabit optical port is selected, only
multi-address can be supported). It can be modified according to
project deployment.
Default Port
Select default network card, and then the network card will forward the
data packet of non-adjacent segment (such as WAN) as default port.
IP Address
After network card is selected, you can set its IP address, subnet
mask, default gateway, preferred DNS server address and alternate
DNS server address.
Subnet Mask
Preferred DNS
Default Gateway
Alternate DNS
