Measurement Group: Link Usage

Measurement Type: Simple

Description: The number of times a link was closed due to manual action. This count indicates the number of times that a link transitioned from ASP-ACTIVE to ASP-INACTIVE as a direct result of someone changing the link administrative state from Enabled to Disabled.

Collection Interval: 30 min

Peg Condition: This measurement is incremented by one each time:

The link administrative state is changed from Enabled to Disabled, causing a protocol state transition from ASP-ACTIVE to ASP-INACTIVE.

Measurement Scope: NE, Server

Recovery:

If the link is known to be under maintenance, then no further action is necessary. If the link was not known to be under maintenance, then link status can be viewed from the GUI main menu under SS7/Sigtran>Maintenance>Links.
View the event history from the GUI main menu under Alarms & Events>View History looking for Event ID 19234. Event ID 19234 shows the manual link state transitions and contains a time-stamp of when the change occurred.
The security logs from the GUI main menu under Security Logs can be searched using the time-stamp from the event history log to determine which login performed the manual state change on the link.
