tunable-optics

This command assigns channels to tunable optic interfaces (T-SFP+) for specific wavelengths.

Syntax

tunable-optics sfpp channel channel_number

Command Default

The T-SFP+ optic defaults to a "no wavelength" state before being activated.

Modes

Interface configuration mode

Usage Guidelines

Tunable SFP+ optics are optional hardware that can be installed with optical SFPs.

If you are installing a T-SFP+ in a 144S port, the T-SFP+ optic needs to be installed in both ends of the cable. The T-SFP+ at each end of the cable link must be configured at the same wavelength by setting them to the same channel on each device.

Failure to duplicate the channel setting may allow the link to come online, but the link behavior may be erratic.

If the firmware determines an error is exceeding a specified limit, a RASLOG message event occurs and the port is taken offline.

The T-SFP+ interface defaults to a "no wavelength" state. When a supported Extreme device boots, the firmware sets the desired wavelength of the T-SFP+ optic.

When a T-SFP+ interface is installed it is very important that the interface is configured to the same channel (wavelength) at both ends. Use the show media tunable-optic-sfpp command to determine the currently configured channel.

T-SFP+ interfaces are tuned to specific wavelengths and frequencies using pre-defined channels.

Refer to the Extreme SLX-OS Monitoring Configuration Guide for complete information on tunable optics.

The following tables lists the frequency and wavelength assigned to channels for tunable SFP+ optic interfaces.
