Subscribing to Managed Object Value Updates using SNMP
By default, the Dell Networking system displays some unsolicited SNMP messages (traps) upon certain events and
conditions.
You can also configure the system to send the traps to a management station. Traps cannot be saved on the system.
FTOS supports the following three sets of traps:
• RFC 1157-defined traps — coldStart, warmStart, linkDown, linkUp, authenticationFailure, and
egpNeighbborLoss.
• Force10 enterpriseSpecific environment traps — fan, supply, and temperature.
• Force10 enterpriseSpecific protocol traps — bgp, ecfm, stp, and xstp.
To configure the system to send SNMP notifications, use the following commands.
1. Configure the Dell Networking system to send notifications to an SNMP server.
CONFIGURATION mode
snmp-server host ip-address [traps | informs] [version 1 | 2c |3]
[community-string]
To send trap messages, enter the keyword traps.
To send informational messages, enter the keyword informs.
To send the SNMP version to use for notification messages, enter the keyword version.
To identify the SNMPv1 community string, enter the name of the community-string.
2. Specify which traps the Dell Networking system sends to the trap receiver.
CONFIGURATION mode
snmp-server enable traps
Enable all Dell Networking enterprise-specific and RFC-defined traps using the snmp-server enable traps
command from CONFIGURATION mode.
Enable all of the RFC-defined traps using the snmp-server enable traps snmp command from
CONFIGURATION mode.
3. Specify the interfaces out of which FTOS sends SNMP traps.
CONFIGURATION mode
snmp-server trap-source
The following example lists the RFC-defined SNMP traps and the command used to enable each. The coldStart and
warmStart traps are enabled using a single command.
Example of RFC-Defined SNMP Traps and Related Enable Commands
snmp authentication SNMP_AUTH_FAIL:SNMP Authentication failed.Request with
invalid community string.
snmp coldstart SNMP_COLD_START: Agent Initialized - SNMP COLD_START.
SNMP_WARM_START:Agent Initialized - SNMP WARM_START.
snmp linkdown PORT_LINKDN:changed interface state to down:%d
snmp linkup PORT_LINKUP:changed interface state to up:%d
