386 Asymmetric Flow Control
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
{symmetric|asymm
etric}
Use this command to enable or disable the symmetric or asymmetric flow control
on the switch. Asymmetric here means that Tx Pause can never be enabled. Only
Rx Pause can be enabled.
no flowcontrol
{symmetric|asymm
etric}
Use the no form of this command to disable symmetric or asymmetric flow
control.
flowcontrol
Use this command to enable or disable the symmetric flow control on the switch.
no flowcontrol Use the no form of this command to disable the symmetric flow control.
Default Flow control is disabled.
