Syntax
flowcontrol rx {off | on} tx {off | on} threshold {<1-2047> <1-2013> <1-2013>}
The threshold keyword is supported on C-Series and S-Series only.
Parameters

E-Series: rx on tx on
S-Series: rx off tx off
Command Modes
INTERFACE
half Enter the keyword half to set the physical interface to transmit only in one direction.
full Enter the keyword full to set the physical interface to transmit in both directions.
Version 8.1.1.0 Introduced on E-Series ExaScale
Version 7.6.1.0 Introduced on S-Series
Version 7.5.1.0 Introduced on C-Series
Version 6.4.1.0 Introduced
Note: Starting with Dell Networking OS 7.8.1.0, when a copper SFP2 module with catalog
number GP-SFP2-1T is used in the S25P model of the S-Series, its speed can be manually set
with the speed command. When the speed is set to 10 or 100 Mbps, the duplex command
can also be executed.
speed (for 10/100/1000 interfaces) Set the speed on the Base-T Ethernet interface.
negotiation auto Enable or disable auto-negotiation on an interface.
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.
threshold
(C-Series and
S-Series only
)
When tx on is configured, you can set the threshold values for:
Number of flow-control packet pointers: 1-2047 (default = 75)
Flow-control buffer threshold in KB: 1-2013 (default = 49KB)
Flow-control discard threshold in KB: 1-2013 (default= 75KB)
