Examples with Address org.snmp4j.smi.Address used on opensource projects

Example 1 with Address

use of org.snmp4j.smi.Address in project openhab1-addons by openhab.

the class SnmpGenericBindingProvider method parseAddress.

Example 2 with Address

use of org.snmp4j.smi.Address in project openhab1-addons by openhab.

the class SnmpBinding method processPdu.

/**
     * Will be called whenever a {@link PDU} is received on the given port
     * specified in the listen() method. It extracts a {@link Variable}
     * according to the configured OID prefix and sends its value to the event

        // at least some SNMP devices send traps from a random port number. Otherwise the trap
