Setting Flow Control
The
flow
command can be used to enable or disable (the default) flow control on a specific port, a range
of ports, or all ports on an entire switch (slot). When the buffers on a receiving device are full, flow
control transmits pause frames to the remote link partner to delay transmission. The local port can delay
transmission of data if the remote link partner transmits a pause frame.
Note.
If auto-negotiation is implemented and enabled for the interface, the pause mode for this interface is
determined by auto-negotiation.
Enabling Flow Control
To enable flow control on an entire switch, enter
flow
followed by the slot number. For example, to enable
flow control on slot 2 enter:
-> flow 2
To enable flow control on a single port, enter
flow
followed by the slot number, a slash (
/
), and the port
number. For example, to enable flow control on port 3 on slot 2 enter:
-> flow 2/3
To enable flow control on a range of ports, enter
flow
followed by the slot number, a slash (
/
), the first
port number, a hyphen, and the last port number. For example, to enable flow control on ports 1 through 3
on slot 2 enter:
-> flow 2/1-3
As an option, you can document the interface type by entering
ethernet
,
fastethernet
, or
gigaethernet
before the slot number. For example to enable flow control on the interface on slot 2 port 3 and document
the interface type as Fast Ethernet enter:
-> flow fastethernet 2/3
Disabling Flow Control
To disable flow control on an entire switch, enter
no flow
followed by the slot number. For example, to
disable flow control on slot 2 enter:
-> no flow 2
To disable flow control on a single port, enter
no flow
followed by the slot number, a slash (
/
), and the
port number. For example, to disable flow control on port 3 on slot 2 enter:
-> no flow 2/3
To disable flow control on a range of ports, enter
no flow
followed by the slot number, a slash (
/
), the first
port number, a hyphen, and the last port number. For example, to disable flow control on ports 1 through 3
on slot 2 enter:
-> no flow 2/1-3
