Viewing the Reason for Last System Reboot Using SNMP
• To view the reason for last system reboot using SNMP, you can use any one of the applicable SNMP commands:
The following example shows a sample output of the snmpwalk command to view the last reset reason.
[DellEMC ~]$ snmpwalk -c public -v 2c 10.16.133.172 1.3.6.1.4.1.6027.3.26.1.4.3.1.7
DELL-NETWORKING-CHASSIS-MIB::dellNetProcessorResetReason.stack.1.1 = STRING: Reboot by
Software
DELL-NETWORKING-CHASSIS-MIB::dellNetProcessorResetReason.stack.2.1 = STRING: Reboot by
Software
DELL-NETWORKING-CHASSIS-MIB::dellNetProcessorResetReason.stack.3.1 = STRING: Cold Reset
[DellEMC ~]$
[DellEMC ~]$ snmpwalk -c public -v 2c 10.16.133.172 1.3.6.1.4.1.6027.3.26.1.4.3.1.8
DELL-NETWORKING-CHASSIS-MIB::dellNetProcessorResetTime.stack.1.1 = STRING:
2017-11-1,5:43:44.0
DELL-NETWORKING-CHASSIS-MIB::dellNetProcessorResetTime.stack.2.1 = STRING:
2017-11-1,5:43:44.0
DELL-NETWORKING-CHASSIS-MIB::dellNetProcessorResetTime.stack.3.1 = STRING:
MIB Support to Display Egress Queue Statistics
Dell Networking OS provides MIB objects to display the information of the packets transmitted or dropped per unicast or multicast egress
queue. The following table lists the related MIB objects:

Monitoring BGP sessions via SNMP
This section covers the monitoring of BGP sessions using SNMP.
BGP SNMP support for non-default VRF uses a SNMP context to distinguish multiple BGP VRF instances within a single BGP process.
SNMP context is a repository of management information that can be accessed through the SNMP agent. SNMP supports multiple
contexts in a device. SNMPv3 has a context name eld in its PDU, which automatically allows the context name eld to be mapped to a
particular VRF instance without having to be mapped to a community map. SNMPv2c context has to be mapped to a community map. A
new CLI command, snmp context, under BGP context, has been introduced to perform this function.
To map the context to a VRF instance for SNMPv2c, follow these steps:
1 Create a community and map a VRF to it. Create a context and map the context and community, to a community map.
