Class: SNMP::SNMPv2

The PDU class for traps in SNMPv2c. Methods are provided for retrieving the values of the mandatory varbinds: the system uptime and the OID of the trap. The complete varbind list is available through the usual varbind_list method. The first two varbinds in this list will always be the uptime and trap OID varbinds.

Methods

encode sys_up_time trap_oid

Attributes

source_ip [RW] Returns the source IP address for the trap, usually derived from the source IP address of the packet that delivered the trap.

    def encode
        encode_pdu(SNMPv2_Trap_PDU_TAG)
    end

sys_up_time()

Returns the value of the mandatory sysUpTime varbind for this trap.

Throws InvalidTrapVarbind if the sysUpTime varbind is not present.

    def sys_up_time
        varbind = @varbind_list[0]
        if varbind && (varbind.name == SYS_UP_TIME_OID)
            return varbind.value
        else
            raise InvalidTrapVarbind, "Expected sysUpTime.0, found " + varbind.to_s
        end
    end

trap_oid()

Returns the value of the mandatory snmpTrapOID varbind for this trap.

Throws InvalidTrapVarbind if the snmpTrapOID varbind is not present.

# File lib/snmp/pdu.rb, line 275
    def trap_oid
        varbind = @varbind_list[1]
        if varbind && (varbind.name == SNMP_TRAP_OID_OID)
            return varbind.value
        else
            raise InvalidTrapVarbind, "Expected snmpTrapOID.0, found " + varbind.to_s 
        end
