The default is None. • (From a management station) Identify the physical location of the system (for example, San Jose, 350 Holger Way, 1st floor lab, rack A1-1). CONFIGURATION mode snmpset -v version -c community agent-ip sysLocation.0 s "location-info" You may use up to 55 characters. The default is None. 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. • Dell Networking enterpriseSpecific environment traps - fan, supply, and temperature. • Dell Networking 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 Example of RFC-Defined SNMP Traps and Related Enable Commands 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. snmp authentication string. snmp coldstart SNMP_AUTH_FAIL:SNMP Authentication failed.Request with invalid community SNMP_COLD_START: Agent Initialized - SNMP COLD_START.
