Connection Settings

connection
Port Bonding
The Allocation ports and the Redundant ports for the NAS interface can be set as operating mode of member port and bonding
port.
Point
-
The following ports cannot be selected for bonding ports.
-
Port of CM different from the master port
-
Port to which a NAS interface has already been assigned
-
Duplicated port
The operating mode that will be the method of determining the communication ports from the bonding ports can be selected
from the following.
Mode
0 Load distribution
(round robin)
1 Active backup
2 Load distribution
(EXCLUSIVE OR)
4 IEEE802.3ad
5 Load distribution
(link speed[only transmit])
6 Load distribution
(link speed[transmit and receive])
Further, when the operating mode is "load distribution (EXCLUSIVE OR)" or "IEEE802.3ad", has policy is set as the method of
determining the port.
There are the two following configuration methods.
-
Method 1
1.
Create a NAS interface of an Active-Standby connection.
2.
Again, create a NAS interface. During this, specify the "Redundant port of the NAS
interface" created in step 1 as the port.
-
Method 2
1.
Create a NAS interface of a Single connection.
2.
Again, create a NAS interface. During this, specify the "port of the NAS interface"
created in step 1 as the Redundant port.
Name
Performs load distribution using round robin.
Communicates on one port, and when communication is not
possible, switches over to other ports. This does not perform load
distribution.
Performs load distribution based on EXCLUSIVE OR of recipient/
sender
Performs load distribution following the IEEE802.3ad standard.
As it communicates with the switch using Link Aggregation Control
Protocol, an 802.3ad-compatible switch is required.
Transmit performs load distribution in line with Link speed. Receive
is only performed on one port.
Send performs load distribution in line with Link speed. Receive
appropriately allocates communicate ports to each communication
partner.
