Cisco Aps Config Span

1.3.6.1.4.1.9.10.72.1.2.1.1

The span (hopByHop or endToEnd) for the APS group. hopByHop This refers to linear APS, e.g. linear SONET APS, or hopByHop CDL APS. In a DWDM system, an APS channel may be associated with either an individual wavelength or an optical fiber. All APS channels within an APS group must be of the same type. Systems that support linear APS on an individual wavelength basis, must assign an ifIndex to each such wavelength. endToEnd This refers to path APS, e.g. endToEnd CDL APS. In this configuration, each APS channel in the APS group is associated with an endToEnd user path. This codepoint does not apply to interfaces with an ifType value of 'sonet'. This object may not be modified if the associated cApsConfigRowStatus object is equal to 'active'. DEFVAL { hopByHop } ::= { cApsConfigExtEntry 1 } SYNTAX INTEGER { noYcable(1), ycable(2), ycableXconnectCommon(3) } MAX-ACCESS read-create STATUS current DESCRIPTION The Y-cable configuration for the APS group associated with user channels. noYcable The APS channels in the APS group are not connected to an external Y-cable. ycable Two user-side interfaces (not necessarily SONET or CDL) are connected to an external y-cable and are grouped into an APS group for endToEnd APS. The received user signal is split in the y-cable coupler and is received on both the interfaces. However, only one interface must transmit toward the user at any given time. With cApsConfigYcable set to 'ycable', the cApsConfigSpan must be set to 'endToEnd'. There must be only two APS channels in an APS group with cApsConfigYcable set to 'ycable'. ycableXconnectCommon This refers to a configuration where two user-side interfaces are connected to an external y-cable. The two signals received on these interface are connected to the same cross connect in the switch. The switch fabric selects one of the two received signals, duplicates it, and forwards it to two network side interfaces grouped for 1+1 linear APS. The received signal from the network side is transmitted to only one user-side interface. cApsConfigSpan is ignored if cApsConfigYcable is set to 'ycableXconnectCommon'. There must be only two APS channels in an APS group with cApsConfigYcable set to 'ycableXconnectCommon'. This object may not be modified if the associated cApsConfigRowStatus object is equal to 'active'. If this object is set to 'ycable' or 'ycableXconnectCommon', the user must shut one of the two channels before setting cApsConfigRowStatus to 'notInService'. DEFVAL { noYcable } ::= { cApsConfigExtEntry 2 } SYNTAX Integer32 (1..120) MAX-ACCESS read-create STATUS current DESCRIPTION This object is instantiated only when the standby interface is not monitored. If both interfaces go down and the standby interface is not monitored, successive switchovers may be used in order to search for an interface that is up. This object specifies the minimum time interval between switchovers when both interfaces go down. A backoff algorithm should be used to increase the time interval between successive switchovers. DEFVAL { 2 } ::= { cApsConfigExtEntry 3 } SYNTAX Integer32 (1..120) UNITS "seconds This object is instantiated only when the standby interface is not monitored. If both interfaces go down and the standby interface is not monitored, successive switchovers may be used in order to search for an interface that is up. This object specifies the maximum time interval between switchovers when both interfaces go down. DEFVAL { 32 } ::= { cApsConfigExtEntry 4 } SYNTAX Integer32 (1..120) UNITS "seconds This object specifies the value of the timer to control the minimum interval between switchovers. After a switchover, APS is re-enabled only after this amount of time has elapsed, in order to prevent quick successive switchovers. DEFVAL { 3 } ::= { cApsConfigExtEntry 5 } SYNTAX CApsMessageTransport MAX-ACCESS read-create STATUS current DESCRIPTION This object specifies the type of transport configured for exchange of APS protocol messages. The type of transport currently being used is indicated in the cApsStatusMessageTransport object. When this object is set to 'ip', values must be specified for the cApsConfigFarEndIpAddressType, cApsConfigFarEndIpAddress and cApsConfigFarEndGroupName objects. DEFVAL { autoSelect } ::= { cApsConfigExtEntry 6 } SYNTAX Integer32 (100..10000) UNITS "milliseconds The value specified in this object applies when the value of cApsStatusMessageTransport is 'dcc', 'ip', or 'osc'. APS messages are exchanged between systems to support bidirectional or linear operation. To avoid potential system misbehavior in which APS messages would be triggered in an uncontrolled fashion, a hold down timer is introduced that prevents successive event-triggered APS messages from being sent in too short a time interval. This object specifies the minimum time between event driven requests. DEFVAL { 5000 } ::= { cApsConfigExtEntry 7 } SYNTAX Integer32 (2..10) MAX-ACCESS read-create STATUS current DESCRIPTION The value specified in this object applies when the value of cApsStatusMessageTransport is 'dcc', 'ip', or 'osc'. The maximum number of APS messages that can be sent within one cApsConfigMessageHolddown interval. DEFVAL { 2 } ::= { cApsConfigExtEntry 8 } SYNTAX Integer32 (1000..120000) UNITS "milliseconds The value specified in this object applies when the value of cApsStatusMessageTransport is 'dcc', 'ip', or 'osc'. An APS message is sent unconditionally, whenever the amount of time specified by this object has elapsed since the last transmission of an APS message. DEFVAL { 15000 } ::= { cApsConfigExtEntry 9 } SYNTAX SnmpAdminString (SIZE (0..32)) MAX-ACCESS read-create STATUS current DESCRIPTION The value specified in this object applies when the value of cApsStatusMessageTransport is 'dcc', 'ip', or 'osc'. APS messages, used to support bidirectional or linear operation, can be sent out-of-band over an IP network. In this case, this object is used to specify the a textual name for the APS group at the far-end to which the message is being sent. ::= { cApsConfigExtEntry 10 } SYNTAX InetAddressType MAX-ACCESS read-create STATUS current DESCRIPTION This object can be set only when the value of cApsConfigMessageTransport is 'ip'. This object specifies the type of IP address defined in cApsConfigFarEndIpAddress. DEFVAL { ipv4 } ::= { cApsConfigExtEntry 11 } SYNTAX InetAddress MAX-ACCESS read-create STATUS current DESCRIPTION This object can be set only when the value of cApsConfigMessageTransport is 'ip'. This object specifies the IP address of the far end, which is used as the destination address in APS messages transmitted by this network element. ::= { cApsConfigExtEntry 12 } SYNTAX SEQUENCE OF CApsStatusExtEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION This table augments the cApsStatusTable. ::= { cApsExtMIBObjects 3 } SYNTAX CApsStatusExtEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION A conceptual row in the cApsStatusExtTable.
