Add a Cisco Nexus Switch

You can add Cisco Nexus switches as a data source in vRealize Network Insight.

Note: If you have a Nexus device configured with multiple Virtual Device Contexts (VDC) then you need to individually specify VDC associated IP address as separate data sources.

Prerequisites

You must verify the following information:

• The data source and its version is supported in vRealize Network Insight. For more information, see Supported Products and Versions.
• The data source follows VMware Ports and Protocols supported in vRealize Network Insight. For more information, see VMware Ports and Protocols.

You must have the following permissions:

• Read-only user: vRealize Network Insight requires read-only third-party device credentials (passwords) to access the SSH data. This user needs to have the Network Operator role. These passwords are added when configuring the third-party data provider in vRealize Network Insight user interface.
• Read-only SNMP user: vRealize Network Insight uses SNMP to collect metrics information from third-party devices (switches, routers, firewalls, and so on). The third-party devices must have SNMP enabled and be accessible from vRealize Network Insight.
