srCommunityTable are currently set to MGR. This procedure must be performed from one of the
existing trusted managers, but not the one that is being deleted.
• Remove the appropriate row from the snmpTargetAddrTable.
The change takes effect immediately. The deleted trusted manager cannot access the device.
The agent automatically removes the row in the tgtAddressMaskTable.
¾ To delete the final Trusted Manager, take these 2 steps:
(The following procedure assumes that there is at least one configured read-write community.
There is currently only one Trusted Manager. The taglist for columns for all rows in the
srCommunityTable are currently set to MGR. This procedure must be performed from the final
Trusted Manager.
1. Set the value of the TransportLabel field on each row in the srCommunityTable to the empty
string.
2. Remove the appropriate row from the snmpTargetAddrTable
The change takes effect immediately. All managers can now access the device.
15.7.3 SNMP Ports
The SNMP Request Port is 161 and the Trap Port is 162. These ports can be changed by setting
parameters in the device ini file. The parameter name is:
SNMPPort = <port_number>
Valid UDP port number; default = 161
This parameter specifies the port number for SNMP requests and responses. Usually, it should
not be specified. Use the default.
15.7.4 Multiple SNMP Trap Destinations
An agent can send traps to up to five managers. For each manager, set the manager’s IP
address, receiving port number and enable sending traps to that manager.
To configure the trap managers table use:
• The Embedded Web Server, refer to Section
5.6.1.3 on page 119.
• The ini file, refer to Section
15.7.1.1 below.
• SNMP, refer to Section
15.7.1.2 on page 233.
15.7.4.1 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).
Note that several traps may be lost until the resolving is complete.
