# Balancing Chain - it could be central-block, terminal-1/2 or member.
Note 1 - Group 1 must be enabled before enable Group 2 to coupling.
Note 2 - When Group 1 or 2 is enabled, the configuration of Group 3 will be disabled.
Note 3 - When Group 3 is enabled, the configuration of Group 1 and 2 will be
disabled.
State
When ring is complete, it will show "Normal".
When ring is incomplete (at least one link is down), it will show "Fail".
Ring Port(s) Each ring port must be unique, CANNOT be configured in different groups; 2 ring
ports between ring/chain CANNOT be the same.
# When role is ring/master, one ring port is forward port and another is block port.
The block port is redundant port; it is blocking port in normal state.
# When role is ring/slave, both ring ports are forward port.
# When role is coupling/primary, only need one ring port named primary port.
# When role is coupling/backup, only need one ring port named backup port. This
backup port is redundant port; it is blocking port in normal state.
# When role is dual-homing, one ring port is primary port and another is backup
port. This backup port is redundant port; it is blocking port in normal state.
# When role is chain/head, one ring port is member port and another is head port.
Both ring ports are forwarding port in normal state.
# When role is chain/tail, one ring port is member port and another is tail port. The
tail port is redundant port; it is blocking port in normal state.
# When role is chain/member, both ring ports are member port. Both ring ports are
forwarding port in normal state.
# When role is balancing-chain/central-block, one ring port is member port and
another is block port. The block port is redundant port; it is blocking port in normal
state.
# When role is balancing-chain/terminal-1/2, one ring port is member port and
another is terminal port. Both ring ports are forwarding port in normal state.
# When role is balancing-chain/member, both ring ports are member port. Both ring
ports are forwarding port in normal state.
