xcvr

Xcvr management module.

This module provide APIs to set and get transceiver transmit and receive laser frequencies.

namespace eos

class xcvr_mgr

#include <xcvr.h>

The xcvr manager. This class configures a transceiver for an interface. If this is a multilane interface, the configuration must be specified for the first lane (eg, Ethernet1/1).

Public Functions

virtual ~xcvr_mgr()

virtual void frequency_is(intf_id_t intf_id, uint32_t rx, uint32_t tx) = 0

Configures both transmit and receive laser frequencies. For modules which support concurrent tuning, using this call will cause the module to tune rx and tx lasers concurrently. The frequency is specified in GHz.

For modules which do not support concurrent tuning, the rx tuning is done first, then the tx.

virtual void rx_fine_frequency_is(intf_id_t intf_id, float freq) = 0

Configures the receive laser fine frequency. The frequency is specified in GHz.

virtual void rx_frequency_is(intf_id_t intf_id, uint32_t freq) = 0

Configures the receive laser frequency. The frequency is specified in GHz.

virtual void tx_frequency_is(intf_id_t intf_id, uint32_t freq) = 0

Configures the transmit laser frequency. The frequency is specified in GHz.

virtual void tx_disabled_is(intf_id_t intf_id, bool disable) = 0

Configures the transmit laser disable.

virtual float rx_fine_frequency(intf_id_t intf_id) const = 0

Returns the currently active receive laser fine frequency. The frequency is in GHz.

virtual uint32_t rx_frequency(intf_id_t intf_id) const = 0

Returns the currently active receive laser frequency. The frequency is in GHz.

virtual uint32_t tx_frequency(intf_id_t intf_id) const = 0

Returns the currently active transmit laser frequency. The frequency is in GHz.

virtual bool tx_disabled(intf_id_t intf_id) const = 0

Returns the transmit laser disable.

virtual void tx_output_power_is(intf_id_t intf_id, float power) = 0

Configures the transmit laser output power.

virtual float tx_output_power(intf_id_t intf_id) const = 0

Returns the transmit laser power.

virtual int32_t tx_turnup_state(intf_id_t intf_id) const = 0

Get the turn up state of a coherent transmit laser. Note that currently, only CFP2 transceivers are supported. Parameters: intf_id: The name of an Ethernet interface associated with the Returns: The value of the turnUp state as of the last polling interval. If the transceiver is not a supported type, or the transceiver is not a coherent optic, returns -1.

virtual int32_t rx_turnup_state(intf_id_t intf_id) const = 0

Get the turn up state of a coherent transmit laser. Note that currently, only CFP2 transceivers are supported. Parameters: intf_id: The name of an Ethernet interface associated with the Returns: The value of the turnUp state as of the last polling interval. If the transceiver is not a supported type, or the transceiver is not a coherent optic, returns -1.

virtual int32_t register_read(intf_id_t intf_id, uint16_t addr, std::string location = "") const = 0

Returns the data in the register/EEPROM address space of the transceiver. Note that currently, only CFP2 transceivers are supported. Parameters: intf_id: The name of an Ethernet interface associated with the transceiver. addr: Specifies the address of the register if the transceiver has a flat address space (such as CFP2). Specifies the offset of the register if the transceiver has a paged address space. location: Specifies the technology specific page/bank of the register if the transceiver has a paged address space. Not used if the transceiver has a flat address space. Returns: The value of the register as of the last polling interval. If the transceiver is not a supported type, or the register requested is not available, returns -1.
