| rbnApsMIB | 1.3.6.1.4.1.2352.2.5 | | | This management information module supports the configuration and
management of SONET linear APS groups. The definitions and
descriptions used in this mib have been derived from
GR-253-CORE Revision 2, January 1999, section 5.3.
The mib contains four tables.
The apsConfigTable supports addition, modification and deletion of
entries representing linear APS groups. Ring APS groups are not
currently supported by this MIB. Entries are indexed by a text
group name. Each entry contains parameters that specify the
configuration of a particular linear APS group.
The apsCommandTable provides linear APS commands that support
protection switching and the ability to modify APS operation.
Commands may only be entered if the corresponding
apsConfigRowStatus instance is set to active.
The apsStatusTable provides statistics and information about
the current APS group state.
The apsChanTable provides the ability to add and delete
SONET LTE channels from APS groups. Additionally
statistics and current state information are provided
at the APS channel level. The table contains entries for
each SONET LTE interface available on the system. The
field apsChanGroupName is initially set to a string of
size zero indicating that the SONET LTE is not part of
an APS group. Fields that are associated with APS configuration
may be modified. An apsChanEntry instance may not be added or
deleted through rbnApsMIB mib access operations. However, an
apsChanEntry may be added or deleted through other
system mechanisms, such as hot swap.
An APS group is created and configured with the following sequence
of events:
CHANNEL CONFIGURATION
Set the apsChanGroupName in an apsChanEntry to a
user-friendly text string. The string must not be equal to
the apsConfigName of an existing apsConfigEntry with
apsConfigRowStatus set to active, since a channel cannot be
added to an active group. The string may be set equal
to the apsConfigName of a row which is currently not
set to active, or it may be set to a string which does
not currently exist in any instance of apsConfigName.
A channel number is entered in apsChanNumber.
A channel priority is entered in apsChanPriority, if
the intended architecture is 1:n. apsChanPriority is
ignored if the architecture is 1+1.
This step is repeated for all apsChanEntry instances
which are to be included in the APS group.
ACTIVATING THE GROUP
If the apsChanGroupName does not exist in an instance
of apsConfigName, an apsGroupEntry is created with
the apsChanGroupName value used as the index for the row.
The apsConfigRowStatus value may be set to createAndGo.
The apsGroupConfigEntry and apsChanEntry instances with
matching name fields will be checked for consistency.
If any errors in the channel numbers, architecture or
configuration are uncovered the apsConfigRowStatus set
will return inconsistentValue , otherwise noError is returned.
If the apsChanGroupName value used in channel configuration
exists in a previously created, inactive apsChanEntry instance,
the apsConfigRowStatus value may be set to active. |

| apsConfig | 1.3.6.1.4.1.2352.2.5.1.1 | | | |
| C32 apsConfigGroups | 1.3.6.1.4.1.2352.2.5.1.1.1 | Counter32 | read-only | The count of APS groups. |
| apsConfigTable | 1.3.6.1.4.1.2352.2.5.1.1.2 | | not-accessible | This table lists the APS groups that have been configured
on the system. |
| apsConfigEntry | 1.3.6.1.4.1.2352.2.5.1.1.2.1 | | not-accessible | A conceptual row in the apsConfigTable. |
| STR apsConfigName | 1.3.6.1.4.1.2352.2.5.1.1.2.1.1 | DisplayString | not-accessible | A textual name for the APS group. |
| BIT apsConfigMode | 1.3.6.1.4.1.2352.2.5.1.1.2.1.2 | Bits | read-create | The architecture and mode of the APS group. The
values mean:
onePlusOne
The 1+1 architecture permanently bridges the working
line to the protection line.
oneToN
The 1:n architecture allows one protection channel to
protect up to n working channels. When a fault is detected
on one of the n working channels that channel is bridged
over the protection channel.
Note: onePlusOne and oneToN are mutually exclusive.
revertive
When the condition that caused a switch to the protection
line has been cleared the signal is switched back to the
working line. If this bit is clear it indicates a
non-revertive system which remains on the protection line
until another switch request is received.
bidirectional
The bi-directional mode provides protection in both
directions.
If this bit is clear it indicates unidirectional mode which
provides protection in one direction. The default for 1:n is
bidirectional. The default for 1+1 is unidirectional.
extraTrafficAllowed
Extra traffic may be carried on the protection channel in
a 1:n architecture if this flag is set. It may be necessary
to disable this in order to interwork with other SONET
network elements that don't support extra traffic.
This object may not be modified if the associated
apsConfigRowStatus object is equal to active(1). |
| I32 apsConfigSdBerThreshold | 1.3.6.1.4.1.2352.2.5.1.1.2.1.3 | Integer32 | read-create | The Signal Degrade Bit Error Rate.
The negated value of this number is used as the exponent of
10 for computing the threshold value for the Bit Error Rate
(BER). For example, a value of 5 indicates a BER threshold of
10^-5.
This object may not be modified if the associated
apsConfigRowStatus object is equal to active(1). |
| I32 apsConfigSfBerThreshold | 1.3.6.1.4.1.2352.2.5.1.1.2.1.4 | Integer32 | read-create | The Signal Failure Bit Error Rate.
The negated value of this number is used as the exponent of
10 for computing the threshold value for the Bit Error Rate
(BER). For example, a value of 5 indicates a BER threshold of
10^-5.
This object may not be modified if the associated
apsConfigRowStatus object is equal to active(1). |
| I32 apsConfigWaitToRestore | 1.3.6.1.4.1.2352.2.5.1.1.2.1.5 | Integer32 | read-create | The Wait To Restore period in seconds.
This field only applies if revertive switching is enabled,
otherwise this value is ignored. After clearing of a
condition that necessitated an automatic switch, the
wait to restore period must elapse before reverting.
This is intended to avoid rapid switch oscillations.
This object may not be modified if the associated
apsConfigRowStatus object is equal to active(1). |
| ROW apsConfigRowStatus | 1.3.6.1.4.1.2352.2.5.1.1.2.1.6 | RowStatus | read-create | The status of this APS group entry.
An entry may not exist in the active state unless all
objects in the entry have an appropriate value.
If this object is set to destroy, all associated instances of
apsChanGroupName will be set to a string of size 0 and all
associated instances of apsChanNumber will be set to 0. |

modeMismatch
Modes other than 1+1 unidirectional monitor protection line
K2 bit 5, which indicates the architecture and K2 bits
6-8, which indicate if the mode is unidirectional or
bidirectional. A conflict between the current local mode
and the received K2 mode information constitutes a
mode mismatch.
channelMismatch
This bit indicates a mismatch between the transmitted K1 channel
and the received K2 channel has been detected.
psbf
This bit indicates a Protection Switch Byte Failure (PSBF) is
in effect. This condition occurs when an invalid code or
persistently unacceptable codes in the K1 byte are received.

accepted on the protection line. |
| C32 apsStatusModeMismatches | 1.3.6.1.4.1.2352.2.5.1.3.1.4 | Counter32 | read-only | A count of Mode Mismatch conditions. |
| C32 apsStatusChannelMismatches | 1.3.6.1.4.1.2352.2.5.1.3.1.5 | Counter32 | read-only | A count of Channel Mismatch conditions. |
| C32 apsStatusPSBFs | 1.3.6.1.4.1.2352.2.5.1.3.1.6 | Counter32 | read-only | A count of Protection Switch Byte Failure conditions.
This condition occurs when an invalid code or persistently
unacceptable codes in the K1 byte are received. |
| TIK apsStatusCreationTime | 1.3.6.1.4.1.2352.2.5.1.3.1.7 | TimeTicks | read-only | The value of sysUpTime at the time the associated
apsConfigRowStatus instance was set to active. |
| apsChan | 1.3.6.1.4.1.2352.2.5.1.4 | | | |
| C32 apsChanLTEs | 1.3.6.1.4.1.2352.2.5.1.4.1 | Counter32 | read-only | The count of available SONET LTE interfaces that may be included
in APS groups. |
| apsChanTable | 1.3.6.1.4.1.2352.2.5.1.4.2 | | not-accessible | This table lists the SONET LTE interfaces that may be included in
APS groups. |
| apsChanEntry | 1.3.6.1.4.1.2352.2.5.1.4.2.1 | | not-accessible | A conceptual row in the apsChanTable. |

| STR apsChanGroupName | 1.3.6.1.4.1.2352.2.5.1.4.2.1.2 | DisplayString | read-write | A textual name for the APS group which this channel is
included in.
This object may not be modified if an instance of
apsConfigName exists with the same value and the associated
apsConfigRowStatus object is equal to active.
If the channel is not part of an APS group this value is set to
a string of size 0.
This field can be changed from a string of size 0 to a value
of apsConfigName which has an associated apsConfigRowStatus
object which is not set to active. This action includes the
SONET LTE into the inactive APS group.
This field can be changed from a string of size 0 to a value
which is not equal to any existing instance of apsConfigName.
This action is the initial step in adding a SONET LTE to a
new APS group. An instance of apsConfigName equal to this
instance of apsChanGroupName will subsequently be created.
If this field is set to any non-empty string it may only
be set to a string of size 0. If an attempt is made to set
this field from a non-empty string to another non-empty string
the error inconsistentValue will be returned. This prevents
a manager from inadvertantly re-assigning a channel. |
| I32 apsChanNumber | 1.3.6.1.4.1.2352.2.5.1.4.2.1.3 | Integer32 | read-write | This field is set to a unique channel number within an APS group.
The value 0 indicates the null channel. The values 1-14 define a
working channel.
If the port is not part of an APS group this value is set to 0.
If an attempt is made to set this field when the associated
apsChanGroupName field is a string of size 0 the error
inconsistentValue is returned.
If an attempt is made to set this field when an associated
apsConfigName field exists and the corresponding apsConfigRowStatus
field is set to active the error inconsistentValue is returned.
This field must be assigned a unique number within the group.
When an attempt is made to set the corresponding apsConfigRowStatus
field to active the apsChanNumber values of all entries with equal
apsChanGroupName fields must represent a set of consecutive integer
values beginning with 0 and ending with n, where n is greater than or
equal to 1 and less than or equal to 14. Otherwise the error
inconsistentValue is returned to the apsConfigRowStatus set attempt. |
| INT apsChanPriority | 1.3.6.1.4.1.2352.2.5.1.4.2.1.4 | INTEGER | read-write | The priority of the channel.
This field deterimines whether high or low priority
SD and SF codes are used in K1 requests.
This field is only applicable if the channel is to be included in
a group using the 1:n architecture. It is not applicable if the
channel is to be included in a group using the 1+1 architecture,
and is ignored in that case. |
| BIT apsChanStatus | 1.3.6.1.4.1.2352.2.5.1.4.2.1.5 | Bits | read-only | Indicates the current state of the port.
