Controls how the system responds to and generates 802.3x pause frames on 10G and 40Gig stack units.
Syntax
flowcontrol rx {off | on} tx {off | on} pause-threshold value [monitor
session-ID]
Parameters
rx on Enter the keywords rx on to process the received flow control frames on this
port. This is the default value for the receive side.
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 this port to the connected
device when a higher rate of traffic is received. This is the default value on the
send side.
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 buffer threshold limit for generating PAUSE frames.
