Receiv
e and Transmit Size Counters
The number of received and transmitted (good and bad) packets split into categories based on their respective frame
sizes.
Receive and Transmit Queue Counters
The number of received and transmitted packets per input and output queue.
Receive Error Counters
Object Description
The number of frames droppe
d due to lack of receive buffers or egress
congestion.
 Rx Drops
The number of frames receive
d with CRC or alignment errors.
 Rx CRC/Alignment
The number of short frames receive
d with valid CRC.
 Rx Undersize
The number of long
frames received with valid CRC.
 Rx Oversize
The number of short frames receive
d with invalid CRC.
 Rx Fragments
The number of long
frames received with invalid CRC.
 Rx Jabber
The number of received frame
s filtered by the forwarding process.
 Rx Filtered
1 Short frames are frames that are smaller than 64 bytes.
2 Long frames are frames that are longer than the configured maximum frame length for this port.
Transmit Error Counters
Object Description
The number of frames droppe
d due to output buffer congestion.
 Tx Drops
The number of frames droppe
d due to excessive or late collisions.
 Tx Late/Exc. Coll.

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
