We have four optical Cisco ONS 15454 MSTP DWDW devices. A we know on these devices, some of the paths through the device are purely optical. We using these on our Production site and DR site connectivity in cluster. We configure all four SNMP but not getting CPU and RAM Information although interfaces are visible but the up down status might not be of much use as we need to monitor our Production and DR sites fiber connectivity.
