specified interface. PAUSE frames are used to temporarily pause the flow of traffic between two

connected devices to help prevent packet loss when traffic congestion occurs between switches.

Syntax Definitions

Platforms Supported

OmniSwitch 6250

By default, flow control is disabled on all switch interfaces.

Usage Guidelines

Flow control is only supported on a standalone switch. It is not supported in a stackable configuration.

Flow control is only supported on interfaces configured to run in full-duplex mode; half-duplex mode

is not supported.

If both autonegotiation and flow control are enabled on the same local interface, autonegotiation calcu-

lates operational flow control settings for that interface. Note that the operational settings, as shown in

the following table, override the configured settings as long as autonegotiation and flow control are

both enabled for the interface:
