New ContributorHi,
TCL run_test file should automatically enable the loopback mode for testing, it should also be logged as well, you may see this in ethernet_100g_loop_off.jpg screenshot.
Occasional ContributorHi,
I have made loop_off in the main.tcl script to check without loopback but still it is showing the tx statistics.
Below I am attaching the screenshots of the system console window.

It seems working as the Rx clk and recover clk are both 0Hz, and lock status = 0, though the MAC status looks weird to me either, would suggest to try some debug and see if the loop_off is correctly set or not first.
the process is in the *\hwtest\altera\alt_aeu_40\eth_ultra_phy_inc.tcl :
proc setphy_lpoff {} {global BASE_RXPHYglobal ADDR_PHY_PMALOOP# puts "RX PHY Register Access: Setting Serial PMA Loopback\n"reg_write $BASE_RXPHY $ADDR_PHY_PMALOOP 0x0reg_read $BASE_RXPHY $ADDR_PHY_PMALOOP}May edit the puts here to see if it's set or not first.

Hi,
I have kept some puts statements in the tcl scripts as you have suggested but for both loopback on and loopback off the rx clk=0 Hz, recover clk=0 Hz, lock status =0 and still it is showing both rx and tx mac stats.Iam sharing the tcl scripts and also I am attaching the screenshot of the system console window for both loopback on and loopback off.

Weird, Rx clock it not on even when loop is on? Are you able to use toolkit to check the Rx CDR when loopback is on?
