To disable flow control capability on a port, enter the following commands.
device(config)
# interface ethernet 0/1/21
device(config-if-e1000-0/1/21)# no flow-control
To enable flow control negotiation, enter the following commands.
device(config)# interface ethernet 0/1/21
device(config-if-e1000-0/1/21)# flow-control neg-on
Syntax: [no] flow-control [ neg-on ]
• flow-control [default] - Enable flow control, flow control negotiation, and advertise flow control
• no flow-control neg-on - Disable flow control negotiation
• no flow-control - Disable flow control, flow control negotiation, and advertising of flow control
After flow control negotiation is enabled using the flow-control neg-on command option, flow control
is enabled or disabled depending on the peer advertisement.
Commands may be entered in IF (single port) or MIF (multiple ports at once) mode.
device(config)# interface ethernet 0/1/21
device(config-if-e1000-0/1/21)# no flow-control
This command disables flow control on port 0/1/21.
device(config)# interface ethernet 0/1/11 to 0/1/15
device(config-mif-0/1/11-0/1/15)# no flow-control
This command disables flow control on ports 0/1/11 to 0/1/15.
Displaying flow-control status
The show interface command with the appropriate parameters displays configuration, operation, and
negotiation status where applicable.
For example, on a FastIron Stackable device, issuing the command for 10/100/1000M port 0/1/21
displays the following output.
device# show interfaces ethernet 0/1/21
