interfaces pause
Configures whether or not the switch will honor or transmit and honor flow control PAUSE frames on the
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.
interfaces slot[/port[-port2]] pause {rx | tx-and-rx | disable}
Syntax Definitions
slot Slot number you want to configure.
port Port number of the interface you want to configure.
port2 Last port number in a range of ports you want to configure.
rx Allows interface to honor PAUSE frames from peer switches and
temporarily stop sending traffic to the peer. Does not transmit PAUSE
frames to peer switches.
tx-and-rx Transmits and honors PAUSE frames when traffic congestion occurs
between peer switches.
disable Disables flow control on the interface.
Platforms Supported
OmniSwitch 6250
Defaults
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:
