- Blocking
Control Whether the instance has “physical” or “logical” control of the ring
port's blocking in the instance's data VLANs.
Second Port The EPSR instance's secondary port.
- 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
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 Whether the instance has “physical” or “logical” control of the ring
port's blocking in the instance's data VLANs
The EPSR instance's setting for the interval between transmissions
of health check messages (in seconds)
The time (in seconds) the EPSR instance waits to receive a health
check message before it decides the ring is down
The minimum time the EPSR instance must remain in the failed
state
Trap Whether the EPSR instance has EPSR SNMP traps enabled
Enhanced
Recovery Whether the EPSR instance has enhanced recovery mode enabled
SLP Priority The EPSR instance's priority (for SuperLoop Prevention)
