Control and monitoring using SNMP 

TCW122B-CM can be configured and monitored through SNMP (Simple Network Management 

Protocol). This could be done using every SNMP v.1 compatible program. Parameters that can be 

changed, are grouped according to their functions in the tables below. To obtain a valid OID 

number it is necessary to replace the “x” symbol with ”1.3.6.1.4.1.38783”. To save the changes 

configurationSaved

 (OID x.3.13.0) should be set to "1".
