5.5  SNMP Management 

The WCM1800 needs to be configured with the details of the SNMP Network Management 

Station before the unit will generate traps, or respond to SNMP polls. 

The SNMP parameters are configured using the SNMP menu found under the 

Management menu 

    

 

 

5.5.1  Read/Write/Trap Community 

To provide a level of security, communities are used to control access to the unit via 

SNMP.  Separate communities may be configured for Read/Write or Trap access. 

5.5.2  Contact Person 

The contact person is the SNMP MIB-2 system SysContact parameter, the default setting 

is: 

 

Metrodata Limited, Fortune House, Eversley Way, Egham, Surrey, TW20 8RY 

The parameter may be up to 255 characters and should be configured to reflect the actual 

installation requirements. 

5.5.3  Node Name 

The node name is the SNMP MIB-2 system SysName parameter.  By default this entry is 

blank.  The parameter may be up to 255 characters and should be configured to reflect the 

actual installation requirements.
