Reset a QSFP+ or QSFP28 Transceiver

Reset a transceiver to simulate removal and reinsertion of the transceiver, which can be helpful in troubleshooting. For example, if authentication of the transceiver fails but you believe the transceiver is a qualified Extreme Networks part, you can reset the transceiver to begin the authentication process again.

About this task

Resetting the transceiver stops traffic and triggers log messages similar to the removal and insertion of the transceiver.

Before you begin

  • Before you use the pluggable-optical-module reset command, ensure the port is administratively down to avoid link flaps.

Procedure

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. Reset the transceiver:
    pluggable-optical-module reset {slot/port[/sub-port]}

    Important

    Not all hardware platforms support these port types. For more information, see your hardware documentation.

Variable Definitions

The following table defines parameters for the pluggable-optical-module reset command.

Variable

Value

{slot/port[/sub-port]}

Specifies location of the transceiver to reset.

Identifies a single slot and port. If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
