TABLE 3-2provides flow control keywords and describes their function.

TABLE 3-2Read-Write Flow Control Keyword Descriptions

KeywordDescription

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 adv_pause_cap = 1, pauses are received.

•If adv_asmpause_cap = 1 while adv_pause_cap = 0, pauses are transmitted.

•If adv_asmpause_cap = 0 while adv_pause_cap = 1, pauses are sent and received.

•If adv_asmpause_cap = 0, then adv_pause_cap determines whether Pause capability is on or off.
