Run the following command to read identification information for the optical module on the target interface: show transceiver interface <interface-type> <interface-number>Run the following command to read identification information for the optical module on the target interface: show transceiver interface <interface-type> <interface-number>Every pluggable optical transceiver (SFP, SFP+, QSFP, QSFP28, etc. ) ships with a small EEPROM that stores two kinds of information: a fixed Serial-ID block (vendor, part number, serial number, capabilities) and—when provided—a diagnostics area (real-time temperature, voltage, TX/RX power, etc. Check compatibility between the optical module and switch Most switch brands have specific compatibility requirements. This article provides instructions on how to view the Optical Module Status on your switch through the Command Line Interface (CLI). The Cisco Small Business Series Switches allow you to plug in a Small Form-factor Pluggable (SFP) transceiver in their optical modules to connect fiber optic cables. • EEPROM data encoded/decoded in key/value pairs. Same API: Any Linux-based NOS, any switch, any module vendor, any module type. Open Source, easy to maintain, easy to extend. OOM HAS A PROBLEM!!! OOM works.
