4.4.4 SFP Module Information

The IGS-20040MT supports the SFP module with digital diagnostics monitoring (DDM) function. This feature is also known
as digital optical monitoring (DOM). You can check the physical or operational status of an SFP module via the SFP Module
Information Page. This Page shows the operational status, such as the transceiver type, speed, wavelength, optical output

congestion.
The number of frames received with CRC or alignment errors.
The number of short frames received with valid CRC.
The number of long frames received with valid CRC.
The number of short frames received with invalid CRC.
The number of long frames received with invalid CRC.
The number of received frames filtered by the forwarding process.
Description
The number of frames dropped due to output buffer congestion.
