Note: To enable TX flow-control, RX flow-control must first be enabled. If
you attempt to enable TX flow-control with RX flow-control disabled,
an error message is displayed.
To configure a port to return to the default behavior of not transmitting pause frames, use the
following command:
disable flow-control tx-pause ports
RX
You can configure the switch to disable the default behavior of responding to received pause
frames. Disabling rx-pause processing avoids dropping packets in the switch and allows for
better overall network performance in some scenarios where protocols such as TCP handle
the retransmission of dropped packets by the remote partner.
To configure a port to disable the processing of IEEE 802.3x pause frames, use the following
command:
disable flow-control rx-pause ports
Note: To disable RX flow-control, TX flow-control must first be disabled. If
you attempt to disable RX flow-control with TX flow-control enabled,
an error message is displayed.
To configure a port to return to the default behavior of enabling the processing of pause
frames, use the following command:
enable flow-control rx-pause ports
Turning Off Autonegotiation on a Gigabit Ethernet Port
In certain interoperability situations, you need to turn autonegotiation off on a fiber gigabit
Ethernet port. Although a gigabit Ethernet port runs only at full duplex, you must specify the
duplex setting.
The following example turns autonegotiation off for port 1 (a 1 Gbps Ethernet port) on a
module located in slot 1 of a modular switch:
configure ports 1:1 auto off speed 1000 duplex full
The 10 Gbps ports do not autonegotiate; they always run at full duplex and 10 Gbps speed.
Running Link Fault Signal
The 10 Gbps ports support the Link Fault Signal (LFS) function. This function, which is
always enabled, monitors the 10 Gbps ports and indicates either a remote fault or a local
