| slSonetApsMib | 1.3.6.1.4.1.4515.1.6.5 | | | This MIB module describes the SiteLight SONET APS. |
| slSonetApsConfig | 1.3.6.1.4.1.4515.1.6.5.1 | | | |
| slSonetApsConfigTable | 1.3.6.1.4.1.4515.1.6.5.1.1 | | not-accessible | This table contains objects to configure APS
(Automatic Protection Switching) feature in a SONET
Line. APS is the ability to configure a pair of SONET
lines for redundancy so that the hardware will
automatically switch the active line from working line
to the protection line or vice versa, within 50ms,
when the active line fails. |
| slSonetApsConfigEntry | 1.3.6.1.4.1.4515.1.6.5.1.1.1 | | not-accessible | An entry is created during startup if the SEEP specifies that there are two trunk ports.
The value of slSonetApsEnable determines if the APS is configured or not. |
| NUM slSonetApsWorkingIndex | 1.3.6.1.4.1.4515.1.6.5.1.1.1.1 | InterfaceIndex | read-only | When a pair of APS lines is configured, one line has
to be the working line, which is the primary line,
and the other has to be the protection line, which
is the backup line. This object refers to the working line
in the APS pair. |
| NUM slSonetApsProtectionIndex | 1.3.6.1.4.1.4515.1.6.5.1.1.1.2 | InterfaceIndex | read-create | The protection line indicates that it will become
the active line when an APS switch occurs (APS switch
could occur because of a failure on the working line). |
| INT slSonetApsEnable | 1.3.6.1.4.1.4515.1.6.5.1.1.1.3 | INTEGER | read-create | This object is used to enable or disable the APS feature
on the working/protection line pairs. |
| INT slSonetApsArchMode | 1.3.6.1.4.1.4515.1.6.5.1.1.1.4 | INTEGER | read-create | This object is used to configure APS architecture mode
on the working/protection line pairs (read-write).
All of the following are supported on single slot.
oneToOne(2) is not supported across 2 slots,i.e. the
working and protection slot numbers must be the same in
oneToOne(2).
onePlusOne : This can be supported on the same card
and across 2 cards.
This mode means that the transmit and receive signals
go only over the active line(which could be working or
protection line). (straight cable implied)
oneToOne : This is supported only on the same card
This mode means that the transmit and receive signals
go over the working and protection lines.
(straight cable implied). |
| INT slSonetApsActiveLineRx | 1.3.6.1.4.1.4515.1.6.5.1.1.1.5 | INTEGER | read-only | This object indicates which Rx line is currently active.
It could be the working line, the protection line or
none if neither working nor protection line is active.
This object reflects the status of receive direction. |
| INT slSonetApsActiveLineTx | 1.3.6.1.4.1.4515.1.6.5.1.1.1.6 | INTEGER | read-only | This object indicates which Tx line is currently active.
It could be the working line, the protection line or
none if neither working nor protection line is active.
This object reflects the status of receive direction.
Not relevant for 1+1. |
| U32 slSonetApsWaitToRestore | 1.3.6.1.4.1.4515.1.6.5.1.1.1.7 | Unsigned32 | read-create | This object contains interval in minutes to wait
before attempting to switch back to working line.
Not applicable if the line is configured in
non-revertive mode, i.e. protection line will
continue to be active, even if failures on the
working line are cleared. The framer clears the
signal-fault and signal-degrade when APS switch
occurs. Please refer to 'slSonetApsRevertive' for
description of non-revertive (read-write). |
| INT slSonetApsDirection | 1.3.6.1.4.1.4515.1.6.5.1.1.1.8 | INTEGER | read-create | This object is used to configure the switching
direction which this APS line supports (read-write).
Unidirectional : APS switch only in one direction.
Bidirectional : APS switch in both ends of the line. |
| INT slSonetApsRevertive | 1.3.6.1.4.1.4515.1.6.5.1.1.1.9 | INTEGER | read-create | This object is used to configure the APS revertive or
nonrevertive option (read-write).
revertive :
Will switch the working line back to active state after
the Wait-To-restore interval has expired and the
working line Signal-Fault/Signal-Degrade has been
cleared. Please refer to 'slSonetApsWaitToRestore' for
description of Wait-To-Restore interval.
nonrevertive :
The protection line continues to be the active line,
The active line does not switch to the working line. |
| INT slSonetApsDirectionOperational | 1.3.6.1.4.1.4515.1.6.5.1.1.1.10 | INTEGER | read-only | This object shows the actual APS direction that is
implemented on the Near End terminal. APS direction
configured through slSonetApsDirection is negotiated with
the Far End and APS direction setting acceptable to
both ends is operational at the Near End. |
| INT slSonetApsArchModeOperational | 1.3.6.1.4.1.4515.1.6.5.1.1.1.11 | INTEGER | read-only | This object shows the actual APS architecture mode that
is implemented on the Near End terminal. APS architecture
mode configured through slSonetApsArchMode object is
negotiated with the Far End through APS channel.
Architecture mode acceptable to both the Near End and
the Far End terminals is then operational at the Near
End. This value can be different than the APS
Architecture mode configured. |
| BIT slSonetApsChanStatus | 1.3.6.1.4.1.4515.1.6.5.1.1.1.12 | Bits | read-only | Indicates the current state of the port.

the channel is prevented from switching to the protection line.
When applied to the null channel, this bit indicates that no
working channel may switch to the protection line.
sdWorking
A signal degrade condition on the working line is in effect.
sdProtecting
A signal degrade condition on the protecting line is in effect.
sfWorking
A signal failure condition on the working line is in effect.
sfProtecting
A signal failure condition on the protecting line is in effect.

| TIK slSonetApsChanLastSwitchover | 1.3.6.1.4.1.4515.1.6.5.1.1.1.15 | TimeTicks | read-only | The value of sysUpTime when this channel last completed a switch
to the protection line. If this channel has never switched to the
protection line, or this channel is the protection line, the value
0 will be returned. |
| BIT slSonetApsLineFailureCodeStatus | 1.3.6.1.4.1.4515.1.6.5.1.1.1.16 | Bits | read-only | The Sonet APS line failure code status - this is the
status of failure encountered by the APS line.
slSonetApsChannelMismatch: trasmitted K1 byte and
received K2 byte do not match.
slSonetApsProtectionByteFail: It could mean either K1 byte
with invalid type of switch
request bits was received, or,
priority of received K1 byte
is lower than the transmitted
K1 byte.

| INT slSonetApsConfigSwitchCommand | 1.3.6.1.4.1.4515.1.6.5.1.1.1.17 | INTEGER | read-create | A switch command initiates one external request for evaluation
(read-write).
(1) Clear - Clears all switch commands on the channel.
(2) Lockout Of Protection - Prevents any of the working channels
from switching to the protection line by issuing a Lockout of
Protection request [unless a request of equal priority (i.e., a
Lockout of Protection) is already in effect].
(3) Forced Switch of Working (to Protection) - Switches the
working channel to the protection line unless a request of equal
or higher priority is in effect, by issuing a Forced Switch
request.
(4) Forced Switch of Protection (to Working) - Switches the
working channel back from the protection line to the working
line unless a request of equal or higher priority is in effect,
by issuing a Forced Switch request. This command applies only
in the 1+1 architecture.
(5) Manual Switch of Working (to Protection) - Switches the
working channel to the protection line unless a request of equal
or higher priority is in effect, by issuing a Manual Switch
request.
(6) Manual Switch of Protection (to Working) - Switches the
working channel back from the protection line to the working
line unless a request of equal or higher priority is in effect,
by issuing a Manual Switch request. This command applies only
in the 1+1 architecture for the null.
(7) Exercise - Exercises the protocol for a protection switch
unless a request of equal or higher priority is in effect, by
issuing an Exercise request and checking the response on the APS
channel.
Reading this variable always returns zero (0). |
| INT slSonetApsLineSwitchReason | 1.3.6.1.4.1.4515.1.6.5.1.1.1.18 | INTEGER | read-only | The reason why APS switch happened. When the working
line on one end fails, its other end is told to do
an APS switch. The following options in the increasing
order of priority indicate what type of switch request
it is.
slSonetApsRevertive : Switch back to working line after the
Wait-to-Restore interval is over, and failures are
cleared. It is the lowest priority.
slSonetApsManual : Manual switch causes APS switch unless a
request of equal or higher priority is in effect.
slSonetApsSignalDefectLow : Switch happened because threshold
for 'slSonetApsSigFaultBER' was exceeded.
slSonetApsSignalDefectHigh : Same as above, but higher priority.
slSonetApsSignalFailureLow : Switch happened because threshold
for 'slSonetApsSigDegradeBER' was exceeded.
slSonetApsSignalFailureHigh : Same as above, but higher
priority.
slSonetApsForceSwitch : Forced switch forces hardware to switch
the active line even if the other line (could be
working line or protection line) is in alarm.
slSonetApsLockOut : This is the highest priority switch. This
will override all other requests.
slSonetApsRemoteRequest : indicates that the local switchover
was in response to a remote request to switch.
slSonetApsLockOut : indicates that the last switchover to the
working occurred because of protection lockout. |

request of equal or higher priority is in effect.
slSonetApsSignalDefectLow : Switch happened because threshold
for 'slSonetApsSigFaultBER' was exceeded.
