Controller or service platform managed networks use SNMP trap receivers for fault notifications. SNMP traps are unsolicited notifications triggered by thresholds or actions, and are an important fault management tool. A SNMP trap receiver is the defined destination for SNMP messages. A trap is generated when a device consolidates event information and transmits the information to an external repository. The trap contains several standard items, such as the SNMP version, community etc. SNMP trap notifications exist for most operations, but not all are necessary for day-to-day operations.
To define a SNMP trap configuration for receiving events at a remote destination:
Setting | Description |
---|---|
IP Address | Type the IP address of an external server resource dedicated to receive SNMP traps on behalf of the controller or service platform |
Port | Set the virtual port of the server resource dedicated to receiving SNMP traps. The default port is port 162 |
Version | Select the SNMP version to send SNMP traps. SNMPv2c is the default version |
Trap Community | Provide a 32 character maximum trap community string. The community string functions like a user id or password allowing access to controller or access point resources. If the community string is correct, the controller provides with the requested information. If the community string is incorrect, the device controller discards the request and does not respond |
