4.2 Using the Trap Sender and Trap Receiver Programs
Table 4–4 Parameters for the snmp_trapsnd Command
Parameter Description
enterprise
For SNMP Version 1, specifies the enterprise object identifier (OID) on whose
behalf the trap is being sent. For example, 1.3.6.1.4.1.1. If you specify 0 or 0.0,
the null OID (0.0) is sent. Make sure that any OID you specify conforms to the
OID rules.
For SNMP Version 2, when specified with the
-v2c
flag, represents the value of
snmpTrapOID.0
.
agent
For SNMP Version 1 traps. Specifies the host name or IP address of the entity on
whose behalf the trap is being generated. You can specify the name
local
, which
is the same as specifying 0, 0.0, 0.0.0, or 0.0.0.0. In these cases, the address
0.0.0.0 is sent as the agent address in the SNMP Version 1 trap PDU.
If the
-v2c
flag is specified, this parameter is ignored.
generic-trap
For SNMP Version 1, specifies the generic trap identifier in the form of a number.
Must be one of the following values:
SNMP Version 1
Value Object
0 coldStart
1 warmStart
2 linkDown
3 linkUp
4 authenticationFailure
5 egpNeighborLoss
6 enterpriseSpecific
For SNMP Version 2, when the
-v2c
flag is specified, this parameter must
contain a valid OID or 0 as the value of
snmpTrapOID
.
specific-trap
For SNMP Version 1, specifies the enterprise-specific trap number. A numeric
value greater than 0 must be present but is ignored if the
-v2c
flag is present or
if
generic-trap
is a value other than 6 (
enterpriseSpecific
).
timeticks
Specifies the timestamp value associated with the generation of the trap
message. The timestamp value is the current time in units of TIMETICKS
(1/100 of a second) since the sending SNMP entity started. A value of 0 causes
snmp_trapsnd
to send the time in hundredths of a second since the operating
system was last booted.
variable_name |
data-type value
Specifies a list of MIB variables to be included in the trap message. For a list of
supported values, including a value for the
Counter64
data type, see Table 4–3.
