User Guidelines
Dell EMC Networking switches implement receive flow control only. They
never issue a flow control PAUSE frame when congested, but will respect
received flow control PAUSE frames received from other switches. Disabling
flow control causes the switch to ignore received PAUSE frames.
Interface specific configuration overrides any global configuration.
Changing the flow control setting on a copper port will restart auto-
negotiation and cause a brief link-flap while auto-negotiation occurs.
Changing the flow control setting on a fiber port may cause a brief link flap as
the PHY is reset.
Enabling flow control on some ports and not others can lead to excessive
packet loss in situations where some ports on the switch have been paused
and the internal packet buffers are consumed. This situation may cause traffic
