How to Check Interface Statistics via CLI on Cisco Nexus 9508 Switch

cisco-nexus

Suppose for some reasons I don't have access to Cisco APIC GUI and I need to check interface statistics of a physical interface of a spine/leaf switch? Which command should I use? Should I go to some special mode of CLI before issuing "show interface x/x"? How?

Because now, if I login to a switch via ssh, I get the following output:

leaf# show interface status
URL: http://127.0.0.1:7777/api//class/nwIf.xml?&target-subtree-class=mgmtMgmtIf&query-target=subtree&order-by=nwIf.id|asc
Code: 403
Output: <?xml version="1.0" encoding="UTF-8"?><imdata totalCount="1"><error code="403" text="Need a valid webtoken cookie (named APIC-Cookie) or a signed request with signature in the cookie APIC-Request-Signature for all REST API requests"/></imdata>

I think you are looking for the show interface <slot/port> command. This is run from the enable mode. For example

switch# show interface e4/2
Ethernet4/2 is down (Link not connected)

There are mayany variations of the show interface command that are detail in various Cisco document, like Cisco NX-OS Interfaces Commands.
