flow-control
Syntax
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) is enabled for the given Priority Code Point. Only one priority may be enabled for PFC per interface. PFC is only supported on JL365A 8P 40G QSFP+ Adv Mod and JL366A 6P 40/100G QSF28 line modules.
The no form disables flow control support on the current interface.
