Publication Date:  2012-07-25 Views:  66 Downloads:  0
Issue Description

NMS system was upgraded from T2000 V2R4 to U2000 V1R2. after some time customer noticed that interface under ne explorer for LCAS V1.0 is not available.

Problem is related to NG SDH equipment with V1R3 version, devices with higher version are supporting LCAS V2.0 and configuration view is available.

Alarm Information
Handling Process

To support LCAS V1.0 it is required to change u2000 configuration file as follow:


#| lcasv1 switch. 0:unsupport, 1:support
lcas = 0 

After reconfiguration NMS restart is required.


Root Cause

Due to poor stability LCAS V1.0 was controlled attribute. to prevent users randomly enabling the lcas function. T2000 did not provide the LCAS function by default since version V2R1. All the operation interfaces and operation entries related to the lcas were hidden under T2000. LCAS function could be displayed by modifying the configuration items on the t2000.
