Subscribing To Managed Object Value Updates Using Snmp - Dell Z9000 Configuration Manual

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.
Dell Networking OS 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 Dell Networking OS sends SNMP traps.
CONFIGURATION mode
snmp-server trap-source
