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
• snmp-server context context1
• snmp-server context context2
• snmp mib community-map vrf1 context context1
• snmp mib community-map vrf1 context context2
2 Congure snmp context under the VRF instances.
• sho run bgp
• router bgp 100
• address-family ipv4 vrf vrf1
• snmp context context1
• neighbor 20.1.1.1 remote-as 200
• neighbor 20.1.1.1 no shutdown
• exit-address-family
• address-family ipv4 vrf vrf2
• snmp context context2
