flow-control

Description

Enables negotiation of receive flow control on the current interface. The switch advertises rx support to the link partner. The final configuration is determined based on the capabilities of both partners.

Priority-based flow control (PFC) on the 3225 switch only takes effect after the configuration is saved to startup-config and the switch is restarted.

The no form of this command disables flow control support on the current interface.
