Chapter 8: Port Parameter Commands
168
When flow control is activated, a port sends out a
PAUSE packet whenever it wants the end node to
stop sending packets. Possible values are:
disabled No flow control.
enabled Flow control is activated.
auto The switch sets flow control to match
flow control on the end node
connected to the port. If the end node
is using flow control, the switch port
also uses flow control. If the end node
is not using flow control, neither will
the switch port.
fctrllimit Specifies the number of cells for flow control. A cell
represents 64 bytes. The range is 1 to 57,344 cells.
The default is 57,344 cells.
backpressure Controls backpressure on the port. Backpressure
applies only to ports operating in half-duplex mode.
Possible values are:
yes, on, true, enabled Activates backpressure on
the port. These values are
equivalent.
no, off, false, disabled Deactivates backpressure
on the port. This is the
default. These values are
equivalent.
bplimit Specifies the number of cells for backpressure. A cell
represents 64 bytes. The range is 1 to 57,344 cells.
The default is 57,344 cells.
bcastfiltering Controls the broadcast filter. These parameters are
equivalent. Possible values are:
yes, on, true, enabled The port forwards
broadcast frames. These
values are equivalent.
no, off, false, disabled The port discards all
ingress broadcast frames.
These values are
equivalent.
holbplimit Specifies the threshold at which the switch signals a
head of line blocking event on a port. The threshold
is specified in cells. A cell is 64 bytes. The range is 1 to
61,440 cells; the default is 58,000.
