The normal running of an ASON network depends on effective
routine maintenance. The purpose of routine maintenance is to find
and solve problems in time.
Querying the Performance of the Control Plane
Users can view the current and history performance data and the record of performance threshold crossing events of the control plane. In this manner, users can monitor the performance of the ASON trail.
Querying Abnormal ASON Events
During routine maintenance, you need to query abnormal events to check the running status of the network.
Checking the Running Status of ASON Trails
During routine maintenance, you must periodically check the running status of ASON trails to check whether the trail attributes are changed and to ensure the normal running of the trails.
Checking TE Links
During routine maintenance, you need to know the resource utilizations of TE links. First, check the number of TE links in the entire network. Then, check the remaining resources of each TE link. The number of TE links should be consistent with the number of TE links that are used. The remaining resources of the TE links on two adjacent nodes on one fiber should be the same.
Checking Control Links
During routine maintenance, you need to check the number and status of control links.
