ETHERNET PROTECTION SWITCHED RING (EPSRING™) COMMANDS
SHOW
EPSR
- Status - Status Whether the ring port is forwarding (Forwarding) or blocking
(Blocked), or has link down (Down), and if forwarding or blocking,
“(logical)” indicates the instance has only logically set the blocking
state of the port because it does not have physical control of it.
- Direction The ring port on which the last EPSR control packet was received is
indicated by “Upstream”. The other ring port is then “Downstream”
- Is On
Common
Segment
- Is On
Common
Segment
Whether the ring port is on a shared common segment link to
another node, and if so, “(highest rank)” indicates it is the highest
priority instance on that common segment.
- Blocking
Control
- Blocking
Control
Whether the instance has “physical” or “logical” control of the ring
port's blocking in the instance's data VLANs.
Secondary
Port
Second Port The EPSR instance's secondary port.
- Status - Status Whether the ring port is forwarding (Forwarding) or blocking
(Blocked), or has link down (Down), and if forwarding or blocking,
“(logical)” indicates the instance has only logically set the blocking
state of the port, because it does not have physical control of it. Note
that on a master configured for SuperLoop Prevention (non-zero
priority) its secondary ring port can be physically forwarding, but
logically blocking. This situation arises when it is not the highest
priority node in the topology (and so does not receive LINKS-DOWN
messages upon common segment breaks) and a break on a common
segment in its ring is preventing reception of its own health
messages.
- Direction The ring port on which the last EPSR control packet was received is
indicated by “Upstream”. The other ring port is then “Downstream”
- Is On
Common

- Blocking
Control
Whether the instance has “physical” or “logical” control of the ring
port's blocking in the instance's data VLANs
Hello Time The EPSR instance's setting for the interval between transmissions of
health check messages (in seconds)
Failover
Time
The time (in seconds) the EPSR instance waits to receive a health
check message before it decides the ring is down
Ring Flap
Time
The minimum time the EPSR instance must remain in the failed state
Trap Trap Whether the EPSR instance has EPSR SNMP traps enabled
