SNMP Agent Device Edit
The DEVICES section in the SNMP server (agent) specify which remote SNMP devices traps or informs should be sent to as a result of the trap send rules.
Number – A number ranging from 1 to device table size, and was historically referenced in read and write maps as the device to which the map applied. However, with the implementation of device mask in the SNMP agent, the mask is what actually determines which device(s) the trap is sent to, and the same trap may be sent to multiple devices with only one trap rule as a result of the mask implementation. This number is therefore simply a row number on the list for database reference.
Name – Simply a reference in the web UI for the user to identify this device.
PeerName – Provides a definition of where on the network to find the device. The peername in simplest form will be an IP address as illustrated in the XML file example above. However, if the network has access to a DNS server and that server is configured in the network settings of the local device, then peername may be any name that can be found via DNS lookup.
Version – Specifies what SNMP version should be used to send the trap, which in turn determines certain aspects of how the trap message is formatted. Version may be 1, 2, or 3 where 2 really means v2c.
Community – Is the community string as defined for SNMP v1 and v2c.
DevMask – A 32-bit bit mask that allows sending the same trap to multiple devices. Both the trap send rules and the trap devices have a “device mask” (DevMask). This effectively creates device groups in a very simple manner. The bit mask found in the trap send rule is logically ANDed with the bit mask in the device table entry. If the result is non-zero, then the trap is sent to this device.
