IMPORTS Unknown .1.3.6.1.4.1.45.1.6.6.1.2 |
s5EnRedPortTableA table with redundancy status and control for
each redundancy-capable port in the chassis.
The number of entries is determined by the number
of redundancy-capable ports in the chassis.
The ports appearing in this table can be divided into
two categories:
Those with remote fault signaling capability and
those without. The latter kind depends on the port
link status to provide the required redundancy.
Ports that are not capable of supporting redundancy do
not have an entry in this table. SEQUENCE OF S5EnRedPortEntry .1.3.6.1.4.1.45.1.6.6.1.2.1 |
s5EnRedPortEntryA row in the table of redundancy status and
control for each redundancy-capable port in the
chassis. Entries in the table cannot be
created or deleted via SNMP. S5EnRedPortEntry .1.3.6.1.4.1.45.1.6.6.1.2.1.1 |
s5EnRedPortBrdIndxThe index of the slot containing the board on which
the port is located.ro INTEGER .1.3.6.1.4.1.45.1.6.6.1.2.1.1.1 |
s5EnRedPortPortIndxThe index of the port on the board.ro INTEGER .1.3.6.1.4.1.45.1.6.6.1.2.1.1.2 |
s5EnRedPortCapabilityThe redundancy capability of the port:
hwRedOnly(1).....hardware redundancy only.
swRedOnly(2).....software redundacy only.
hwAndSwRed(3)....both hardware and software redundancy.
A value of hwRedOnly(1) or hwAndSwRed(3) means that
the port is capable of being configured into a
hardware-redundant pair. In this case, the identity of the
potential redundant companion is given by the objects
s5EnRedPortCompanionBrdNum and s5EnRedPortCompanionPortNum.
A value of swRedOnly(2) or hwAndSwRed(3) means that
the port is capable of being configured into a
software-redundant pair.ro Enumeration .1.3.6.1.4.1.45.1.6.6.1.2.1.1.3 |
s5EnRedPortRedundModeThe redundancy mode of the port.
The values when written change the redundancy
mode, and when read report the redundancy mode:
standalone(1)..the port is not in any redundant pair.
hwActive(2)....the port is the active companion in
a hardware-redundant pair.
hwStandby(3)...the port is the standby companion
in a hardware-redundant pair.
swActive(4)....the port is the active companion in
a software-redundant pair.
swStandby(5)...the port is the standby companion
in a software-redundant pair.
The values that can be written, which change the
redundancy mode, are:
standalone(1)...causes the redundant pair to be
broken up.
hwActive(2).....if the previous value was hwStandby(3),
this value will cause the port to become
the active port in the hardware-redundant
pair, resulting in a switchover.
hwStandby(3)....if the previous value was hwActive(2),
this value will cause the port to become
the standby port in the hardware-redundant
pair, resulting in a switchover.
swActive(4).....if the previous value was swStandby(5),
this value will cause the port to become
the active port in the software-redundant
pair, resulting in a switchover.
swStandby(5)....if the previous value was swActive(4),
this value will cause the port to become
the standby port in the software-redundant
pair, resulting in a switchover.
To create a hardware-redundant pair, change this object
to hwActive(2) or hwStandby(3). To create a
software-redundant pair, change this object to
swActive(4) or swStandby(5). The same SNMP SET PDU
must also write to objects s5EnRedPortCompanionBrdNum
and s5EnRedPortCompanionPortNum.rw Enumeration .1.3.6.1.4.1.45.1.6.6.1.2.1.1.4 |
s5EnRedPortOperStatusThe redundancy status of the port. The values are:
other(1).............none of the following.
ok(2)...................no fault
localFault(3)....the local port has sensed a fault condition.
remoteFault(4)...the remote port has sensed a fault
condition and has signaled the local port
accordingly.
Either a localFault(3) or remoteFault(4) condition should
cause a healthy redundant port pair to switchover.
If the port does not belong to a redundant pair, a
value of other(1) is returned.
Note: If the redundant link consists of ports without
remote fault capability, the value remoteFault(4)
will not be reported and the value localFault(3)
implies that link is off.ro Enumeration .1.3.6.1.4.1.45.1.6.6.1.2.1.1.5 |
s5EnRedPortRemoteOperStatusThis object reflects the real time status of the
received data from the remote port. The values are:
snpxFLRemFltCpblPortUp(1)....10BASE-FL signaling,
plus capable of SynOptics proprietary
remote fault signaling. A remote fault
on such a port is indicated by
snpxRemFltCpblPortFault(5).
snpxFLFBRemFltCpblPortUp(2)..10BASE-FL signaling,
plus capable of SynOptics proprietary
remote fault signaling and 10BASE-FB
signaling. A remote fault on such a port
is indicated by snpxRemFltCpblPortFault(5).
tenBaseTFLPortUp(3)...........regular idle 10BASE-T
or 10BASE-FL signaling, and is incapable of
remote fault signaling.
tenBaseFBPortUp(4)...........10BASE-FB synchronous
signaling. A remote fault on such a port is
indicated by tenBaseFBPortFault(6).
snpxRemFltCpblPortFault(5)...SynOptics proprietary
remote fault signaling.
tenBaseFBPortFault(6)........10BASE-FB remote fault
signaling.
unknown(7)...................none of the above.
A value of snpxFLRemFltCpblPortUp(1) indicates that
the remote port is using 10BASE-FL signaling, and is
capable of SynOptics proprietary idle and remote fault
signaling. A remote fault on such a port is indicated
by snpxRemFltCpblPortFault(5).
A value of snpxFLFBRemFltCpblPortUp(2) indicates that
the remote port is using 10BASE-FL signaling, and is
capable of SynOptics proprietary idle and remote fault
signaling, and is also capable of synchronous
signaling. A remote fault on such a port is indicated
by snpxRemFltCpblPortFault(5).
A value of tenBaseFLPortUp(3) indicates that the
remote port uses regular idle 10BASE-FL signaling, and
is incapable of remote fault signaling.
A value of tenBaseFBPortUp(4) indicates that the
remote port uses 10BASE-FB synchronous signaling. A
remote fault on such a port is indicated by
tenBaseFBPortFault(6).ro Enumeration .1.3.6.1.4.1.45.1.6.6.1.2.1.1.6 |
s5EnRedPortRemFltSelectModeThis mode specifies the set of local fault events
which will cause a switchover. The values are:
synoptics(1)..The SynOptics Tx Remote Fault events
consist of auto-partition and NM (network
management) partition events in addition to
the standard events.
standard(2)...The standard events are link-off for
all ports, and low light, jabber, Rx invalid idle,
Tx dark, and Tx remote fault (for diagnostics)
for ports with transmit remote fault
capability.rw Enumeration .1.3.6.1.4.1.45.1.6.6.1.2.1.1.7 |
s5EnRedPortTxModeThe Transmit Fiber Mode, which determines the
port transmit idle. The values are:
autoCfg(1)...The port will auto configure based
upon the received idle.
fl(2)........The port is configured in FL mode.
fb(3)........The port is configured in FB mode.
other(4).....None of the above. The port is not a fiber
port.
The value other(4) is read-only.rw Enumeration .1.3.6.1.4.1.45.1.6.6.1.2.1.1.8 |
s5EnRedPortFaultsA count of local or remote faults on this port. This
counter increments on a transition between the fault
and no-fault states.ro Counter .1.3.6.1.4.1.45.1.6.6.1.2.1.1.9 |
s5EnRedPortModeChangesA count of the number of times this port has transitioned
from standby mode to non-standby mode (includes active
mode and standalone mode), or vice versa.ro Counter .1.3.6.1.4.1.45.1.6.6.1.2.1.1.10 |
s5EnRedPortCompanionBrdNumThe index of the slot containing the board of the
other port in the redundant pair.
If the port (whose slot-port identity is given by
the instance) is hardware-redundant capable, this
object has the value of the slot number of the
(potential) redundant companion, even if the port is
in standalone mode. This allows the network
manager to determine the identity of the potential
companion, which is fixed by the hardware of the
board.
Changing this object is permitted only when creating a
software-redundant pair.rw INTEGER .1.3.6.1.4.1.45.1.6.6.1.2.1.1.11 |
s5EnRedPortCompanionPortNumThe index of the other port in the redundant pair.
If the port (whose slot-port identity is given by
the instance) is hardware-redundant capable, this object
has the value of the port number of the (potential)
redundant companion, even if the port is in standalone
mode. This allows the network manager to determine
the identity of the potential companion, which is fixed
by the hardware of the board.
Changing this object is permitted only when creating a
software-redundant pair.rw INTEGER .1.3.6.1.4.1.45.1.6.6.1.2.1.1.12 |
s5EnRedPortSwitchoverStatusThe switchover status of the port (and its companion).
The following values can be written:
timedSwitchover(2)...cause a timed switchover
(see value of
s5EnRedPortSwitchoverTime)
The following values reflect the switchover
status of the redundant port pair:
other(1)..............not undergoing switchover
timedSwitchover(2)....port is undergoing timed switchover
(see value of
s5EnRedPortSwitchoverTime).
On GETs with switchover status of timedSwitchover(2),
if the time remaining before the completion of the
switchover and reversal is available, it will be reported
in object s5EnRedPortSwitchoverTime as a positive value
If not available, the value of s5EnRedSwitchoverTime will
be zero. When changing a port to timedSwitchover(2), the
SET request must also contain the value for object
s5EnRedSwitchoverTime.rw Enumeration .1.3.6.1.4.1.45.1.6.6.1.2.1.1.13 |
s5EnRedPortSwitchoverTimeThe length of time between switching over a redundant
port pair and switching back, when a timed switchover
is done to the port. This object can only be written
in the same request that sets
s5EnRedPortSwitchoverStatus to timedSwitchover(2).
Afterwards, it indicates the amount of time left
before the timed switchover is completed, at which
time another switchover occurs and
s5EnRedSwitchoverStatus is changed to other(1). This
object has the value of zero if the port is not
undergoing a timed switchover, or if the amount of
time is not available.rw TimeIntervalSec .1.3.6.1.4.1.45.1.6.6.1.2.1.1.14 |
s5EnRedLastChgThe value of sysUpTime when the last change in the
redundant ports table was observed by the agent.ro TimeTicks (SNMPv2-SMI) .1.3.6.1.4.1.45.1.6.6.1.2.2 |
