flow-control

Syntax

On the 8320 switch series:

flow-control rx

[no] flow-control rx

On the 8325 switch series:

flow-control {rx | priority <PRIORITY>}

[no] flow-control [rx | priority <PRIORITY>]

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 8325 switch only, takes effect after the configuration is saved to startup-config and the switch is restarted.

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

Command context

Authority

priority <PRIORITY>: On the 8325 switch only, enables priority-based flow control on the current interface and sets the priority number. Range: 0 to 7.
