Users Guide
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

MIB Object OID Object Values Description
dF10SysLogTraps 1.3.6.1.4.1.6027.3.30.1.1 1 = reachable2 = unreachable Specifies whether the syslog
server is reachable or
unreachable.
The 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
Following example shows the SNMP trap that is sent when connectivity to the syslog server is resumed:
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (10230) 0:01:42.30 SNMPv2-
MIB::snmpTrapOID.0 = OID: SNMPv2-
SMI::enterprises.6027.3.30.1.1.2 SNMPv2-SMI::enterprises.6027.3.30.1.1 = STRING:
"REACHABLE: Syslog server
10.11.226.121 (port: 9140) is 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 05:26:04: dv-fedgov-s4810-6: %EVL-6-REACHABLE:Syslog server 10.11.226.121 (port: 9140)
is reachable
Copy Configuration Files Using SNMP
To do the following, use SNMP from a remote client.
• copy the running-config file to the startup-config file
• copy configuration files from the Dell Networking system to a server
• copy configuration files from a server to the Dell Networking system
You can perform all of these tasks using IPv4 or IPv6 addresses. The examples in this section use IPv4 addresses; however, you can
substitute IPv6 addresses for the IPv4 addresses in all of the examples.
The following table lists the relevant MIBs for these functions are.
