Description
Enables a local port to send pause frames to a remote port. Enter send on when a
remote port is set to receive on or receive desired.
Prevents a local port from sending pause frames to a remote port. Enter send off
when a remote port is set to receive off or receive desired.
Indicates preference to send pause frames, but autonegotiates flow control. You can
enter send desired when a remote port is set to receive on, receive off, or receive
desired.
Enables a local port to process pause frames that a remote port sends. Enter receive
on when a remote port is set to send on or send desired.
Prevents a local port from processing pause frames. Enter receive off when a remote
port is set to send off or send desired.
Indicates preference to process pause frames, but autonegotiates flow control. You
can enter receive desired when a remote port is set to send on, send off, or send
desired.
