Tap Configuration

TX Tap Autotune

Enable or disable the automatic receiving of PHY retuning (see PP_PHYRETUNE), which is performed on the 25G interfaces as soon as a signal is detected by the transceiver. Useful if a bad signal causes the PHY to continuously retune or if for some other reason it is preferable to use manual retuning (PP_PHYRETUNE).

Corresponding CLI command: PP_PHYAUTOTUNE

# TX Tap Autotune
await port.serdes[0].phy.autotune.set(on_off=enums.OnOff.ON)
await port.serdes[0].phy.autotune.set_on()
await port.serdes[0].phy.autotune.set(on_off=enums.OnOff.OFF)
await port.serdes[0].phy.autotune.set_off()

resp = await port.serdes[0].phy.autotune.get()
resp.on_off

TX Tap Retune

Trigger a new retuning of the receive equalizer on the PHY for one of the 25G serdes. Useful if e.g. a direct attached copper cable or loop transceiver does not go into sync after insertion. Note that the retuning will cause disruption of the traffic on all serdes.

Corresponding CLI command: PP_PHYRETUNE

# TX Tap Retune
await port.serdes[0].phy.retune.set(dummy=1)

TX Tap Configuration

Control and monitor the equalizer settings of the on-board PHY in the transmission direction (towards the transceiver cage) on Thor and Loki modules.

Corresponding CLI command: PP_PHYTXEQ

# TX Tap Configuration
await port.serdes[0].phy.tx_equalizer.set(pre2=0, pre1=0, main=86, post1=0, post2=0, post3=0)
resp = await port.serdes[0].phy.tx_equalizer.get()
resp.pre2
resp.pre
resp.main
resp.post
resp.pre3_post2 # pre3 for Freya (112G Serdes), post2 for Thor (56G Serdes)
resp.post3

RX Tap Configuration

RX EQ parameters.

Note

For non-Freya Modules.

Corresponding CLI command: PP_PHYRXEQ

# RX Tap Configuration
await port.serdes[0].phy.rx_equalizer.set(auto=0, ctle=0, reserved=0)

resp = await port.serdes[0].phy.rx_equalizer.get()
resp.auto
resp.ctle
