: Bonding group
Configure a Bonding group using neighboring
ports
- CM#0 CA#1 Port#0 and CM#0 CA#1 Port#1
- CM#0 CA#1 Port#2 and CM#0 CA#1 Port#3
- CM#1 CA#1 Port#0 and CM#1 CA#1 Port#1
- CM#1 CA#1 Port#2 and CM#1 CA#1 Port#3
Configure a multipath using ports with
the same port number
- CM#0 CA#1 Port#0 and CM#1 CA#1 Port#0
- CM#0 CA#1 Port#1 and CM#1 CA#1 Port#1
- CM#0 CA#1 Port#2 and CM#1 CA#1 Port#2
- CM#0 CA#1 Port#3 and CM#1 CA#1 Port#3
If each Bonding group connects to a different system (segment) and one of the ports become inaccessible,
the other Bonding group port continues the connection.

Inaccessible
If Port#0 cannot be accessed,
continued access is performed
with Port#1 and a failover is
not performed.
If the other port also becomes inaccessible, the failover function is executed, and the IP address is taken
over by a port of a different controller. In this case, the other Bonding groups (B and D) are not affected by
this operation.
