Enable the routing table
bypass feature.
route-option bypass-route
By default, the routing table bypass
feature is disabled.
This command is not available for the
DHCP and path jitter operations.
Configuring the collaboration feature
Collaboration is implemented by associating a reaction entry of an NQA operation with a track entry.
The reaction entry monitors the NQA operation. If the number of operation failures reaches the
specified threshold, the configured action is triggered.
To configure the collaboration feature:
Step Command
Remarks
1.
Enter system view.

and enter NQA operation
view.
nqa entry admin-name

By default, no NQA operation is
created.
3.

Configuring threshold monitoring
This feature allows you to monitor the NQA operation running status.
Threshold types
An NQA operation supports the following threshold types:
•
average
—If the average value for the monitored performance metric either exceeds the upper
threshold or goes below the lower threshold, a threshold violation occurs.
•
accumulate
—If the total number of times that the monitored performance metric is out of the
specified value range reaches or exceeds the specified threshold, a threshold violation occurs.
