Description
Use the flow-control command to enable flow control on the current Ethernet port.
Use the undo flow-control command to disable flow control on the port.
Suppose flow control is enabled on both the local and peer switches. When congestion
occurs on the local switch,
z the local switch sends a message to notify the peer switch of stopping sending
packets to itself temporarily,
z the peer switch will stop sending packets to the local switch temporarily when it
receives the message; and vice versa. By this way, packet loss is avoided and the
network service operates normally.
By default, flow control is disabled on a port.
Example
# Enable flow control on the Ethernet1/0/1 port.
