Configuring Flow Control on a Port
You can enable or disable flow control of a port, which manages traffic rates during congestion.
If a port experiences congestion and cannot receive any more traffic, flow control notifies the
other port to stop transmitting until the condition clears. By default, flow control of the ports on
the Corecess R1-SW24L2B is disabled.
To change flow control status, use the following command in Global configuration mode:
Command Task
port <port-type> <slot>/<port>
flowctl <status>
1. Configure the flow control of the specified port.
y <port-type>: The type of Ethernet port to configure.
-
fastethernet
: Configures Fast Ethernet port.
-
gigabitethernet
: Configures Gigabit Ethernet port.
y <slot>: Slot number (1 ~ 3)
y <port>: Port number (1 ~ 8/24)
y <status>: Flow control status
-
auto
: Auto negotiation.
-
off
: Disables flow control on the port.
-
on
: Enables flow control on the port.
The following example enables flow control on the
Gigabit Ethernet port 1/2
:
(config)# port gigabitethernet 1/2 flowctl on
(config)#
