flowcontrol
Configures which type of IEEE 802.3x flowcontrol is used on Gigabit Ethernet interfaces.
Syntax: flowcontrol {asymmetric | symmetric}
no flowcontrol
Description: Flow control controls traffic rates during periods of congestion.
Use the flowcontrol asymmetric command to allow the local port to determine whether flow control will be performed on the remote port. During periods of local port congestion, the local port will send a pause request for the remote port to stop transmitting.
Use the flowcontrol symmetric command to allow the local port to perform flow control only if the remote port can also perform flow control. If the remote port is not able to perform flow control locally, the local port will also not perform flowcontrol.
Factory Default: Symmetric.
Command Mode: Gigabit Ethernet interface configuration.
Example: In the following example:
- The interface gbe command specifies Gigabit Ethernet interface and changes the command mode to interface configuration
- The flowcontrol asymmetric command to sets flow control for this interface to asymmetric.
- The show command displays the new setting:
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#interface gbe 1/34/1
router(config-if)#flowcontrol asymmetric
router(config-if)#show
interface gbe 1/34/1
