Moxa EDS-4012 port numbers and info mismatch
2 posts
I am using Switch Port Mapper across many switch manufacturers and it works great except for Moxa, specifically EDS-4012. The port numbers do not match what I'm seeing on the switch, as well as some of the other information that is not being pulled in when compared to Cisco, Hirschmann, Lantronix, etc.
I have seen from other forum posts here that sending a SnmpWalk .csv file of all the OIDs might help. Please see the attached and let me know if there is any additional information that might be helpful.

Thanks for your help.
We've investigated the port numbering discrepancy that you are seeing in Switch Port Mapper for your Moxa EDS-4012-8P-4GS switch. Here is what's happening:
The Moxa switch uses SNMP interface indices (1-12) that don't directly correspond to the physical port labels you see on the device panel:
SNMP Interface Indices 1-4 = Physical Ports G1, G2, G3, G4 (Gigabit SFP)
SNMP Interface Indices 5-12 = Physical Ports Port 1-8 (Fast Ethernet)
The physical port labels (G1-G4, Port 1-8) are printed directly on the switch housing and are not exposed through the standard SNMP protocol that Switch Port Mapper uses to query device information. This is a hardware labeling choice by Moxa and is common across many network devices.
Workaround:
You can use the custom port comments feature in Switch Port Mapper to assign the correct physical port names. Open Switch Port Mapper, locate each interface and add a comment (press F2) with the correct physical port label (e.g., "G1", "Port 1", etc.). This will ensure your port maps and reports accurately reflect your physical cabling, even though the underlying SNMP indices differ.
