EX Commands

This chapter provides EX (exercise) commands for the Cisco ONS 15454, ONS 15327, ONS 15600 and ONS 15310-CL.

13.1  EX-SW-<OCN_BLSR>

Exercise Protection Switch (OC12, OC48, OC192)

See Table 27-1 on page 27-1 for supported modifiers by platform.

Usage Guidelines

Cisco ONS 15454, ONS 15327, ONS 15600, ONS 15310-CL

This command exercises the algorithm for switching from a working facility to a protection facility without actually performing a switch. It is assumed that the facility being exercised is the working unit. The exercise switching success or failure result will be indicated by an automatic alarm.

Exercise switch for the SONET protection line is not supported in this release. If sending this command to the protection unit, an error message will be returned. In addition to all normal INPUT, EQUIPAGE, PRIVILEGE error codes, the following error codes are also included in this command:

SNVS (Status, Not in Valid State)

SROF (Status, Requested Operation Failed)

SSRD (Status, Switch Request Denied)

Note•If you send the EX-SW-<OCN_BLSR> command to both east and west sides/spans of a two-fiber or four-fiber ring within a short time period (less than 30-45 seconds) the system will only execute one (WEST) side EXER-RING query, and preempt the other (EAST) side query. There will be no event messages reported for the preempted side, and it will be in APS-CLEAR switching state.

Examples of sending the EX-SW-<OCN_BLSR> command to both east and west sides/spans of a two-fiber or four-fiber ring within a short time period (less than 30-45 seconds) are: (a) A single command with both side/span AIDs (in the list AID format) of the same two-fiber or four-fiber ring or (b) Separate queries (through TL1 or CTC, or TL1 and CTC) on both sides/spans of the same two-fiber or four-fiber ring

•DIRN is an optional parameter. A NULL value of this parameter defaults to BTH for a two-fiber or four-fiber BLSR protection group.

DIRN follows these rules:

–TRMT will always fail for any kind of protection groups

–For two-fiber and four-fiber BLSR protection groups both the RCV and TRMT direction will fail.

–Only BTH is a valid parameter. EX-SW-<OCN_TYPE> can be operated only on BLSR protection groups.

Parameter and Values
Description

AID

Access identifier from the "25.1.14  FACILITY" section on page 25-28. Identifies the facility in the NE to which the switch request is directed

SWITCHTYPE

Switch type. Must not be null

Parameter type is SWITCH_TYPE—BLSR switch type. MANWKSWBK, MANWKSWPR, FRCDWKSWBK, FRCDWKSWPR, LOCKOUTOFPR, and LOCKOUTOFWK are retrieve-only values for RTRV-PROTNSW-OCn commands. They are not applicable for the OPR-PROTNSW-OCn commands. RING and SPAN are the only allowed values for BLSR protection

•FRCDWKSWBK

Working unit is forced to switch back to working

•FRCDWKSWPR

Working unit is forced to switch to the protection unit

•LOCKOUTOFPR

Lockout of protection

•LOCKOUTOFWK

Lockout of working

•MANWKSWBK

Manual switch of working unit back to working

•MANWKSWPR

Manual switch of working unit back to the protection unit

•RING

BLSR ring switch type

•SPAN

BLSR span switch type

DIRECTION

Direction. A null value defaults to RCV

Parameter type is DIRECTION—transmit and receive direction

•BTH

Both transmit and receive directions

•RCV

Receive direction only

•TRMT

Transmit direction only
