Cisco Nexus 9000 Series switches are high density, programmable Ethernet switches. Nexus 9000 switches allow for faster performance and increased automation within data center deployments. In order for the Network Discovery app to work with virtual routing and forwarding (VRF) instances on a system that uses Nexus 9000 switches, you must configure the SNMP (Simple Network Management Protocol) context on the Nexus 9000.
To configure the SNMP context on a Nexus 9000 switch, run the following command:
snmp-server context context-name [instance instance-name] [vrf {vrf-name | default | management}] [topology topology-name]
Where:
Parameter | Description |
---|---|
context-name | The name of the SNMP context. The context-name can be any alphanumberic string up to 32 characters. |
instance instance-name |
(Optional) Specifies a protocol instance. The instance-name can be any alphanumeric string up to 32 characters. Note: If you don't want to specify a protocol instance, do not
include either of the instance directive or
the instance-name.
|
vrf vrf-name | (Optional) Specifies the VRF (virtual routing and
forwarding) instance. The vrf-name can be
any case-sensitive alphanumeric string up to 32 characters. Note: If you don't want to specify a VRF instance, do not
include either of the vrf directive or the
vrf-name.
|
default-vrf | The default VRF. |
management-vrf | The management VRF. |
topology topology-name | (Optional) Specifies the name of the topology. The
topology-name can be any
alphanumeric string up to 32 characters. Note: If you don't want to specify a topology, do not include
either of the topology directive or the
topology-name.

Users must configure one of the following options to any device the needs to be
discovered:
- Configure SNMPv1
- Configure SNMPv2c
- Configure user and security for the SNMPv3.ser file and security for SNMPv3
