PowerFlex Manager > Resources > Cisco 9 K switch > View details: The performance tab shows no metrics.
Cause: On Cisco Nexus switches, command-line interfaces (CLIs) are run only on the switch. NX-API CLI improves the accessibility of these CLIs by making them available outside of the switch by using HTTP or HTTPS. NX-API uses HTTP or HTTPS as its transport. CLIs are encoded into the HTTP or HTTPS POST body. Starting with Cisco NX-OS Release 9.2(1), the NX-API feature is enabled by default on HTTPS port 443. HTTP port 80 is disabled.
Solution: 1) Log into switch > enable nxapi feature: conf t feature nxapi Note: PFxM 3.6 & higher uses https (NOT http) for status check and metrics fetching, therefore for security reasons, nxapi can be disabled on http ! Enable and configure NXAPI config t feature nxapi ! Disable http, only https supported for security no nxapi http ! Use the management interface only to communicate for NXAPI nxapi use-vrf management PFxM 3.5 & earlier uses https & http for status check and metrics fetching, therefore keep nxapi enabled for http. Note: if we enable the nxapi with feature nxapi command it only listens on HTTPS not HTTP, so we need NXAPI to listen on HTTP ! Enable and configure NXAPI config t feature nxapi nxapi http port 80 2) After making changes on the switch, go to Resources > add check box next to switch > Run Inventory 3) View details now shows switch performance metrics
