Enabling an SNMP Agent to Notify Syslog Server Failure
You can configure a network device to send an SNMP trap in the event of an audit processing failure due
to connectivity issues with the syslog server.
If a connectivity failure occurs on a syslog server that is configured for reliable transmission, an SNMP
trap is sent. Also a message is written to the console indicating that the configured syslog server has
failed.
The SNMP trap is sent only periodically. Meaning, when a syslog connection fails and the time-interval
between the last syslog notification and current time is greater than or equal to 5 minutes, a trap is sent.
This restriction applies to the console message also.
NOTE: If a syslog server failure event is generated before the SNMP agent service starts, then SNMP
trap is not sent successfully.
To enable an SNMP agent to send a trap when the syslog server is not reachable, use the following
command:
CONFIGURATION MODE
snmp-server enable traps snmp syslog-unreachable
To enable an SNMP agent to send a trap when the syslog server resumes connectivity, use the following
command:
CONFIGURATION MODE
snmp-server enable traps snmp syslog-reachable

MIB Object OID Object Values Description

Specifies whether the
syslog server is
reachable or
unreachable.
Following example shows the SNMP trap that is sent when connectivity to the syslog server is lost:
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (19738) 0:03:17.38 SNMPv2-
MIB::snmpTrapOID.0 = OID: SNMPv2-
SMI::enterprises.6027.3.30.1.1.1 SNMPv2-SMI::enterprises.6027.3.30.1.1 =
STRING: "NOT_REACHABLE: Syslog server
10.11.226.121 (port: 9140) is not reachable" SNMPv2-SMI::enterprises.
6027.3.6.1.1.2.0 = INTEGER: 2
Following is the sample audit log message that other syslog servers that are reachable receive:
Oct 21 00:46:13: dv-fedgov-s4810-6: %EVL-6-NOT_REACHABLE:Syslog server
10.11.226.121 (port: 9140) is not reachable
