Trap Manger Configuration via Host Name
One of the five available SNMP managers can be defined using a FQDN. In the current
version, this option can only be configured via the
ini file (SNMPTrapManagerHostName).
The gateway tries to resolve the host name at start up. Once the name is resolved (IP is
found), the resolved IP address replaces the last entry in the trap manager table (defined by
the parameter ‘SNMPManagerTableIP_x’) and the last trap manager entry of
snmpTargetAddrTable in the snmpTargetMIB. The port is 162 (unless specified otherwise),
the row is marked as ‘used’ and the sending is ‘enabled’.
When using 'host name' resolution, any changes made by the user to this row in either MIBs
are overwritten by the gateway when a resolving is redone (once an hour).
Several traps may be lost until the resolving is complete
Trap Managers Configuration via the ini File
In the V7122 ini file, the parameters below can be set to enable or disable the sending of
SNMP traps. Multiple trap destinations can be supported on the device by setting multiple
trap destinations in the
ini file.
SNMPManagerTrapSendingEnable_<x> = 0 or 1 indicates if traps are to be sent to the
specified SNMP trap manager. A value of ‘1’ means that it is enabled, while a value of ‘0’
means disabled.
<x> = a number 0, 1, 2 which is the array element index. Currently, up to 5 SNMP trap
managers can be supported.
Figure 126 presents an example of entries in a device ini file regarding SNMP. The device
can be configured to send to multiple trap destinations. The lines in the file below are
commented out with the ‘;’ at the beginning of the line. All of the lines below are commented
out since the first line character is a semi-colon.
