Symptoms

FACTS: 
In order for PFxM to report switch performance metrics on a Cisco Switch (3 K / 9 K), the following is true:

  • Both HTTP and HTTPS must be enabled on the Cisco switch
  • PFxM uses HTTP to check NXAPI status and then collect metrics using HTTPS, therefore feature nxapi should also be enabled

Symptoms: 

  • 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/HTTPS. 

NX-API uses HTTP/HTTPS as its transport. CLIs are encoded into the HTTP/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.

Resolution

1) Log in to switch > enable nxapi feature:

enable nxapi feature: 

Note: PFxM 3.6 and 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 and earlier uses HTTPS and HTTP for status check and metrics fetching, therefore keep nxapi enabled for HTTP. 
Note: If we enable the nxapi with the 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 changing the switch, go to Resources > add check box next to switch > Run Inventory.

run inventory
