Parameter Description
Operation State Displays the run-time operation state of the X-Ring group.
 For the X-
Ring group denoted as “Ring”, the value is “Standby”, “Edge”, “Mas-
ter” or “Transit”. For the ring topology, there would be exactly one switch stays
in master state and one of two Ring interfaces is set in blocking state.
 For the X-
Ring group denoted as “Coupling”, the value is “Disconnect”,
“Backup”, or “Primary”. There would be maximum one coupling path stays in
“Primary” to forward traffic between two X-Ring networks.
Interface 1 Displays the first member interface for the X-Ring group. The value is either physi-
cal port or LAG (Link-Aggregation-Group) port.
Interface 2 Displays the secondary member interface for the X-Ring group.
 For the X-
Ring group denoted as “Ring”, the value is either physical port or
LAG (Link-Aggregation-Group) port.

For the X-
Ring group denoted as “Coupling”, the value is physical port or LAG
(Link-Aggregation-
Group) port or “None”. The value “None” implies the X-Ring
group is created not for coupling dual-homing application.
Forward State Displays the spanning tree state of the member interface of an X-Ring group. The
value is “Discarding” or “Forwarding”.
 Discarding - Discard traffic in both ingress and egress directions.

Forwarding - Forward ingress traffic bases on the result of forwarding database
lookup.
Master Ring Displays the X-Ring network that is coupling connected by the X-Ring group
denoted as “Coupling”. This field is required for the X-Ring coupling application
only.
