Setting Allowed Host Information; Specifying The Default Snmp Trap Target - Patton electronics SmartNode Series Software Configuration Manual

SmartWare Software Configuration Guide
In the following example the SNMP communities for the default community public with read-only access and
the undisclosed community Not4evEryOne with read/write access are defined. Only these valid communities
have access to the information from the SNMP agent running on the respective SmartNode 1000, 2000 or
4000 series device.
SN2300-01(cfg)#snmp community public ro
SN2300-01(cfg)#snmp community Not4evEryOne rw
Note If no community is set on your SmartNode accessing any of the MIB objects
is not possible!

Setting allowed host information

If a host has to access SNMP MIB objects on a certain node, it explicitly needs the right to access the SNMP
agent on the respective SmartNode 1000, 2000 or 4000 series device. Therefore a host needs an entry on a
SmartNode 1000, 2000 or 4000 series device, which allows accessing the device. The host is identified by its IP
address and has to use a certain community string for security precautions.
Note The community which is to be used as security name to access the MIB
objects has to be defined prior to the definition of allowed hosts.
This procedure describes adding a host that is allowed to access the MIB of this system
Mode: Configure

Use the no command option to remove a SNMP allowed host setting.
Example: Setting allowed host information
In the following example the host with IP address 172.16.224.45 shall be able to access the MIB of this Smart-
Node 2000 series device using community public as security name.
SN2300-01(cfg)#snmp host 172.16.224.45 security-name public

specifying the default SNMP trap target

An SNMP trap is a message that the SNMP agent running on a SmartNode 1000, 2000 or 4000 series device
sends to a network management station. For example, an SNMP agent would send a trap when an interface's
status has changed from up to down. The SNMP agent must know the address of the network management
station so that it knows where to send traps. It is possible to define more than one SNMP trap target.
The SNMP message header contains a community field. The SNMP agent running on a SmartNode 1000, 2000
or 4000 series device uses a defined community name, which is inserted in the trap messages header sent to the
target. In most cases the target is a NMS, which only accepts a SNMP message header of a certain community.
