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.
