4.18.2. Example 2: Assess Link Stability 1000BaseT DUT in Slave mode, with Line and Offset Impairments
This task is performed using the pva_line, pva_tx_clk, pva_speed, pva_gig_mode, and pva_relink commands. Test
Port 1,1 should be connected to a DUT that supports 1000Base-T operation and supports Slave timing mode. Link
stability will be verified using pva_link_mon meter over a 10 second period.
Hint: To force the DUT into Slave mode, the test port needs to be set for Master.
Ideal Result: LINKED, Speed = 1000, MASTER, Count = 100 Remote_Gig_OK
Actual Result: Count = 78
