Parameters

Field	Value	Description
Alarm Event	For example, CP_SER_INT	Displays the alarms in the control plane of an ASON trail.
Suppression Status	Suppressed, Not Suppressed	Sets the suppression status of an alarm.
Severity	Critical, Major, Minor, Warning	Set the severity of the control plane alarm.
Name	For example, NE33ASON-SDH-Trail0001	Displays the name of an ASON trail.
Source (Sink) NE	For example, NE33	Displays the name of the source or sink NE.
Source (Sink) Port	For example, 5-N1SL4-1(SDH-1)	Displays the source or sink port of an ASON trail.
Source (Sink) Timeslot	For example, VC4:1	Displays the source or sink timeslot that an ASON trail uses.
Index	For example, 96	Displays the index number of the ASON trails.
Type	ASON Trail, ASON Server Trail, Differentially Protected ASON Trail, Differentially Protected ASON Server Trail	Displays the type of an ASON trail.
Class	Diamond, Gold, Silver, Copper, Iron	Displays the protection type of the ASON trail. There are five types of ASON trails: diamond, gold, silver, copper and iron. There are three types of ASON server trails: diamond, gold, silver and copper. A diamond service is a service provided with 1+1 protection from its source node to its sink node. It is also called 1+1 service. A gold service is also called a 1:1 service. When a fiber on the path of a gold service is cut, the ASON provides MSP for the service at first. If MSP fails, the ASON reroutes the gold service. A silver service is also called a rerouting service. When an ASON trail is interrupted, periodic rerouting is performed until the rerouting succeeds. During this process, if the original route is recovered, rerouting stops. A copper service is also called an unprotected service. If its trail fails, service is interrupted and there is no rerouting. An iron service can be preempted by a higher class service. For example, the extra service is created by using the protection MSP link of a gold service.
Direction	Bidirectional	Bidirectional: The source and sink ends transmit and receive signals.
Bandwidth Granularity	VC4	Displays the bandwidth granularity of an ASON trail.
Service Status	Primary, Secondary	Displays whether the ASON trail is the primary or the secondary one.
Concatenation Type	Non-Concatenation, Standard Concatenation	Displays the concatenation type of an ASON trail.
Concatenation Count	4, 16, 64	If you set Concatenation Type to Standard Concatenation, Concatenation Count is available. If you select Non-Concatenation, Concatenation Count is null.
Created On	For example, 05/09/2008 11:18:15	Displays the time when the ASON trail was created.
Reroute Lockout	Locked, Unlocked	Specifies whether the ASON trail is rerouting locked. If locked, the trail is not rerouted if it is interrupted.
Rerouting Priority	High, Low, Low and Delayed	Displays the rerouting priority of an ASON trail. Compared with low priority services, high priority services first obtain the link resources during the rerouting.
Revertive Mode	Non-Revertive, Automatically Revertive, Scheduled Revertive	Displays the revertive attribute of a trail during rerouting. It indicates whether a trail can automatically revert to the original route that has been restored after service rerouting.
Source (Sink) Node	For example, 1.1.1.33	Displays the source or sink node ID.
