Enabling an SNMP Agent to Notify
Syslog Server Failure
You can configure a network device to send an SNMP trap if an audit processing failure occurs due to loss of
connectivity with the syslog server.
If a connectivity failure occurs on a syslog server that is configured for reliable transmission, an SNMP trap is
sent and a message is displayed on the console.
The SNMP trap is sent only 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. This restriction also applies to the console
message.
NOTE: If a syslog server failure event is generated before the SNMP agent service starts, the SNMP trap is
not sent.
To enable an SNMP agent to send a trap when the syslog server is not reachable, enter 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, enter the following
command:
CONFIGURATION MODE
snmp-server enable traps snmp syslog-reachable
