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 -v2cflag, 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 -v2cflag 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 -v2cflag 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 -v2cflag is present or

 

if generic-trapis 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

Specifies a list of MIB variables to be included in the trap message. For a list of

data-type value

supported values, including a value for the Counter64 data type, see Table 4–3.
