show interfaces diagnostics optics-profile

Syntax

Description

Display diagnostic data for the supported optics (QSFP+, QSFP28, QSFP-DD). No output is displayed for unsupported optics (SFP, CFP, etc.) and for QSFP DAC (direct attach cables) modules.

Options

interface-name

Interface name. For example:

et-fpc/pic/port
