Parameters
rx on Enter the keywords rx on to process the received flow
control frames on this port.
rx off Enter the keywords rx off to ignore the received flow
control frames on this port.
tx on Enter the keywords tx on to send control frames from the
port to the connected device when a higher rate of traffic is
received.
tx off Enter the keywords tx off so that flow control frames are
not sent from this port to the connected device when a
higher rate of traffic is received.
pause-
threshold
Enter the keyword pause-threshold to configure the
buffer threshold (in Kilobytes) at which the interface starts
transmitting pause frames for link-level flow control. Valid
values are 1 to 12480KB. The default is 60KB.
resume-offset Enter the keyword resume-offset to configure the buffer
threshold (in Kilobytes) at which the interface resumes
transmitting offset frames for link-level flow control. Valid
values are 1 to 12480KB. The default is 9KB.
Defaults An interface ignores flow-control frames received from other network devices (rx
off) and does not transmit pause frames (tx off).

Usage
Information
The globally assigned 48-bit Multicast address 01-80-C2-00-00-01 is used to send
and receive pause frames. To allow full-duplex flow control, stations implementing
the pause operation instruct the MAC to enable the reception of frames with a
destination address equal to this multicast address.
