TABLE 3-2 Read-Write Flow Control Keyword Descriptions
Keyword Description
adv_asmpause_cap The adapter supports asymmetric pause, which means it
can pause only in one direction.
0=Off (default)
1=On
adv_pause_cap This parameter has two meanings, each depending on the
value of
adv_asmpause_cap . (Default=0)
• If adv_asmpause_cap = 1 while a dv_pause_cap = 1,
pauses are received.
• If adv_asmpause_cap = 1 while a dv_pause_cap = 0,
pauses are transmitted.
• If adv_asmpause_cap = 0 while a dv_pause_cap = 1,
pauses are sent and received.
• If adv_asmpause_cap = 0, then a dv_pause_cap
determines whether Pause capability is on or off.
