M4300 Intelligent Edge Series Fully Managed Stackable Switches Asymmetric Flow Control When in asymmetric flow control mode, the switch responds to PAUSE frames received from a peer by stopping packet transmission, but the switch does not initiate MAC control PAUSE frames. When you configure the switch in asymmetric flow control (or no flow control mode), the device is placed in egress drop mode. Egress drop mode maximizes the throughput of the system at the expense of packet loss in a heavily congested system, and this mode avoids head-of-line blocking. flowcontrol Use this command to enable the symmetric or asymmetric flow control on the switch. Asymmetric flow control means you can enable Rx Pause only but not Tx Pause. Default Format Mode Flow control is disabled. flowcontrol {symmetric | asymmetric} Interface Config no flowcontrol This command disables flow control. Format Mode no flowcontrol Global Config show flowcontrol Use this command to display the IEEE 802.3 Annex 31B flow control settings and status for a specific interface or all interfaces. The command also displays 802.3 Tx and Rx pause counts. Priority Flow Control frames counts are not displayed. If the port is enabled for priority flow control, operational flow control status is displayed as Inactive. Operational flow control status for stacking ports is always displayed as N/A. Format Mode show flowcontrol [interface unit/slot/port] Privileged Exec Switching Commands 445 CLI Command Reference Manual
