Control

Inter-frame Gap

The minimum gap between packets in the traffic generated for a port. The gap includes the Ethernet preamble.

Corresponding CLI command: P_INTERFRAMEGAP

# Inter-frame Gap
await port.interframe_gap.set(min_byte_count=20)

resp = await port.interframe_gap.get()
resp.min_byte_count

PAUSE Frames

Whether a port responds to incoming Ethernet PAUSE frames by holding back outgoing traffic.

Corresponding CLI command: P_PAUSE

# PAUSE Frames
await port.pause.set(on_off=enums.OnOff.ON)
await port.pause.set_on()
await port.pause.set(on_off=enums.OnOff.OFF)
await port.pause.set_off()

resp = await port.pause.get()
resp.on_off

Auto-Train

The interval between sending out training packets, allowing a switch to learn the port’s MAC address. Layer-2 switches configure themselves automatically by detecting the source MAC addresses of packets received on each port. If a port only receives, and does not itself transmit test traffic, then the switch will never learn its MAC address. Also, if transmission is very rare the switch will age-out the learned MAC address. By setting the auto-train interval you instruct the port to send switch training packets, independent of whether the port is transmitting test traffic.

Corresponding CLI command: P_AUTOTRAIN

# Auto-Train
await port.autotrain.set(interval=1)

resp = await port.autotrain.get()
resp.interval

Gap Monitor

The gap-start and gap-stop criteria for the port’s gap monitor. The gap monitor expects a steady stream of incoming packets, and detects larger-than-allowed gaps between them. Once a gap event is encountered it requires a certain number of consecutive packets below the threshold to end the event.

Corresponding CLI command: P_GAPMONITOR

# Gap Monitor
await port.gap_monitor.set(start=100, stop=10)

resp = await port.gap_monitor.get()
resp.start
resp.stop

Priority Flow Control

This setting control whether a port responds to incoming Ethernet Priority Flow Control (PFC) frames, by holding back outgoing traffic for that priority.

Corresponding CLI command: P_PFCENABLE

# Priority Flow Control
await port.pfc_enable.set(
    cos_0=enums.OnOff.ON,
    cos_1=enums.OnOff.OFF,
    cos_2=enums.OnOff.ON,
    cos_3=enums.OnOff.OFF,
    cos_4=enums.OnOff.ON,
    cos_5=enums.OnOff.OFF,
    cos_6=enums.OnOff.ON,
    cos_7=enums.OnOff.OFF,
    )

resp = await port.pfc_enable.get()
resp.cos_0
resp.cos_1
resp.cos_2
resp.cos_3
resp.cos_4
resp.cos_5
resp.cos_6
resp.cos_7

Loopback

The loopback mode for a port. Ports can be configured to perform two different kinds of loopback: (1) External RX-to-TX loopback, where the received packets are re-transmitted immediately. The packets are still processed by the receive logic, and can be captured and analyzed. (2) Internal TX-to-RX loopback, where the transmitted packets are received directly by the port itself. This is mainly useful for testing the generated traffic patterns before actual use.

Corresponding CLI command: P_LOOPBACK

# Loopback
await port.loop_back.set(mode=enums.LoopbackMode.L1RX2TX)
await port.loop_back.set_l1rx2tx()
await port.loop_back.set(mode=enums.LoopbackMode.L2RX2TX)
await port.loop_back.set_l2rx2tx()
await port.loop_back.set(mode=enums.LoopbackMode.L3RX2TX)
await port.loop_back.set_l3rx2tx()
await port.loop_back.set(mode=enums.LoopbackMode.NONE)
await port.loop_back.set_none()
await port.loop_back.set(mode=enums.LoopbackMode.PORT2PORT)
await port.loop_back.set_port2port()
await port.loop_back.set(mode=enums.LoopbackMode.TXOFF2RX)
await port.loop_back.set_txoff2rx()
await port.loop_back.set(mode=enums.LoopbackMode.TXON2RX)
await port.loop_back.set_txon2rx()

resp = await port.loop_back.get()
resp.mode

BRR Mode

Selects the Master/Slave setting of 100 Mbit/s, 1000 Mbit/s BroadR-Reach copper interfaces.

Corresponding CLI command: P_BRRMODE

# BRR Mode
await port.brr_mode.set(mode=enums.BRRMode.MASTER)
await port.brr_mode.set_master()
await port.brr_mode.set(mode=enums.BRRMode.SLAVE)
await port.brr_mode.set_slave()

resp = await port.brr_mode.get()
resp.mode

MDI/MDIX Mode

Selects the MDI/MDIX behavior of copper interfaces.

Corresponding CLI command: P_MDIXMODE

# MDI/MDIX Mode
await port.mdix_mode.set(mode=enums.MDIXMode.AUTO)
await port.mdix_mode.set_auto()
await port.mdix_mode.set(mode=enums.MDIXMode.MDI)
await port.mdix_mode.set_mdi()
await port.mdix_mode.set(mode=enums.MDIXMode.MDIX)
await port.mdix_mode.set_mdix()

resp = await port.mdix_mode.get()
resp.mode
