2.8.3 SNMP gateway
The SNMP gateway operates together with NM. To utilize SNMP you will need an SNMP
Management Application. This application will gain access to the status of the TetraFlex
network through the “SNMP Gateway”. This gateway could be a node in the TetraFlex
network. In that case the PC which runs the SNMP Management Application will need to
connect to this “SNMP gateway node” via the WAN connection.
The SNMP gateway must have the SNMP extension agent installed and will need to have
NM running. NM is responsible for updating all of the node status variables, whilst the SNMP
agent will service the SNMP requests.
The SNMP Management Application polls for the node status. Traps are not generated by the
TetraFlex network. This is in accordance with recommendations found in the rfc1157.
The SNMP agent packets can be downloaded from www.damm.dk extranet software
download site.
The SNMP agent packet consists of:
SNMPAgent.dll
This file is the actual SNMP extension agent. It works in correlation with
the Windows SNMP service, which is already installed on the SB421
and BSC412. This extension agent is responsible for servicing SNMP
requests.
SNMP_install.vbs
Script-file which will:
 Stop the Windows SNMP Service.
 Copy SNMPAgent.dll to SNMPAgent_.dll
 Import registry settings required to install SNMPAgent_.dll.
 Modify registry settings to make the SNMP Gateway node auto
logon with the “tetra” user.
 Copy shortcut to NM.bat file into startup folder.
