Administrative and Service States


This appendix describes the administrative and service states for Cisco ONS 15454 SDH cards, ports, and cross-connects. For circuit state information, see Chapter 11 "Circuits and Tunnels." Software Release 5.0 and later states are based on the generic state model defined in Telcordia GR-1093-CORE, Issue 2 and ITU-T X.731.

B.1  Service States

Service states include a Primary State (PST), a Primary State Qualifier (PSTQ), and one or more Secondary States (SST). Table B-1 lists the service state PSTs and PSTQs supported by the ONS 15454 SDH.

Table B-1 ONS 15454 SDH Service State Primary States and Primary State Qualifiers

Primary State, Primary State Qualifier
Definition

Unlocked-enabled

The entity is fully operational and will perform as provisioned.

Unlocked-disabled

The entity is not operational because of an autonomous event.

Locked-disabled

The entity is not operational because of an autonomous event and has also been manually removed from service.

Locked-enabled

The entity has been manually removed from service.


Table B-2 defines the SSTs supported by the ONS 15454 SDH.

Table B-2 ONS 15454 SDH Secondary States 

Secondary State
Definition

automaticInService

The entity is delayed before transitioning to the Unlocked-enabled service state. The transition to the Unlocked-enabled state depends on the correction of conditions, or on a soak timer. Alarm reporting is suppressed, but traffic is carried. Raised fault conditions, whether or not their alarms are reported, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command.

disabled

The entity was manually removed from service and does not provide its provisioned functions. All services are disrupted; the entity is unable to carry traffic.

Note STM-N ports and connections in the disabled state continue to send an Alarm Indication Signal Line (AIS-L).

failed

The entity has a raised alarm or condition.

loopback

The entity is in loopback mode.

mismatchOfEquipment

An improper card is installed, a cross-connect card does not support an installed card, or an incompatible backplane is installed. For example, an installed card is not compatible with the card preprovisioning or the slot. This SST applies only to cards.

maintenance

The entity has been manually removed from service for a maintenance activity but still performs its provisioned functions. Alarm reporting is suppressed, but traffic is carried. Raised fault conditions, whether or not their alarms are reported, can be retrieved on the CTC Conditions tab or by using the TL1 RTRV-COND command.

outOfGroup

The virtual concatenation (VCAT) member cross-connect is not used to carry VCAT group traffic. This state is used to put a member circuit out of the group and to stop sending traffic. Locked-enabled,outOfGroup only applies to the cross-connects on an end node where VCAT resides. The cross-connects on intermediate nodes are in the Locked-enabled,maintenance service state.

softwareDownload

The card is involved in a software download. This SST applies only to cards.

unassigned

The card is not provisioned in the database. This SST applies only to cards.

notInstalled

The card is not physically present (that is, an empty slot). This SST applies only to cards.


B.2  Administrative States

Administrative states are used to manage service states. Administrative states consist of a PST and an SST. Table B-3 lists the administrative states supported by the ONS 15454 SDH. See Table B-2 for SST definitions.


Note When an entity is put in the Locked,maintenance administrative state, the ONS 15454 SDH suppresses all standing alarms on that entity. All alarms and events appear on the Conditions tab. You can change this behavior for the LPBKFACILITY and LPBKTERMINAL alarms. To display these alarms on the Alarms tab, set the NODE.general.ReportLoopbackConditionsOnUnlocked,MaintenancePorts to TRUE on the NE Defaults tab.



Note A change in the administrative state of an entity does not change the service state of supporting or supported entities.


Table B-3 ONS 15454 SDH Administrative States

Administrative State (PST,SST)
Definition

Unlocked

Puts the entity in service.

Unlocked,automaticInservice

Puts the entity in automatic in-service.

Locked,disabled

Removes the entity from service and disables it.

Locked,maintenance

Removes the entity from service for maintenance.

Locked,outOfGroup

(VCAT circuits only) Removes a VCAT member cross-connect from service and from the group of members.


B.3  Service State Transitions

This section describes the transition from one service state to the next for cards, ports, and cross-connects. A service state transition is based on the action performed on the entity.

B.3.1  Card Service State Transitions

B.3.2  Port and Cross-Connect Service State Transitions

Table B-5 lists the port and cross-connect service state transitions. Port states do not impact cross-connect states with one exception. A cross-connect in the Unlocked-disabled,automaticInService service state cannot transition autonomously into the Unlocked-enabled service state until the parent port is Unlocked-enabled.

The following ports do not support all of the service states listed in Table B-5:

E-Series Ethernet ports do not support service states; these ports are either enabled or disabled.

FC_MR-4 ports support the Unlocked-enabled; Locked-enabled,disabled; and Locked-enabled,maintenance service states; they do not support the Unlocked-disabled,automaticInService service state.


Note Deleting a port or cross-connect removes the entity from the system. The deleted entity does not transition to another service state.
