Example of Deriving the Interface Index Number
If you know the interface index, use the following commands to nd the interface number.
DellEMC ~ $ snmpwalk -v 2c -c public 10.16.206.127 .1.3.6.1.2.1.2.2.1.2 | grep 2097156
IF-MIB::ifDescr.2097156 = STRING: TenGigabitEthernet 1/1
DellEMC ~ $ snmpwalk -v 2c -c public 10.16.206.127 .1.3.6.1.2.1.31.1.1.1.1 | grep 2097156
IF-MIB::ifName.2097156 = STRING: TenGigabitEthernet 1/1
You can use the show interfaces command to view the interface index.
DellEMC#show interface Tengigabitethernet 1/21
TenGigabitEthernet 1/21 is up, line protocol is up
Hardware is DellEMCEth, address is f8:b1:56:82:de:70
Current address is f8:b1:56:82:de:70
Pluggable media not present
Interface index is 2097156
MIB Objects for Viewing the System Image on Flash Partitions
To view the system image on Flash Partition A, use the chSysSwInPartitionAImgVers object or, to view the system image on Flash Partition
B, use the chSysSwInPartitionBImgVers object.

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.
sho run snmp
snmp-server community public ro
snmp-server community public ro
snmp-server community vrf1 ro
snmp-server community vrf2 ro
