Flow Control - NETGEAR GS728TS Admin Manual

GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches
• Link Status. Indicates whether the Link is up or down.
• Link Trap. This object determines whether or not to send a trap when link status
changes. The factory default is Enable.
• Enable: Specifies that the system sends a trap when the link status changes.
• Disable: Specifies that the system does not send a trap when the link status
changes.
• Maximum Frame Size. Specify the maximum Ethernet frame size the interface
supports or is configured to support. The frame size includes the Ethernet header,
CRC, and payload. (1518–9216). The default maximum frame size is 1518.
• MAC Address. Displays the physical address of the specified interface.
• PortList Bit Offset. Displays the bit offset value which corresponds to the port when
the MIB object type PortList is used to manage in SNMP.
• ifIndex. The ifIndex of the interface table entry associated with this port. If the
interface field is set to All, this field is blank.

Flow Control

IEEE 802.3x flow control works by pausing a port when the port becomes oversubscribed
and dropping all traffic for small bursts of time during the congestion condition. This can lead
to high-priority and/or network control traffic loss. When IEEE 802.3x flow control is enabled,
lower speed switches can communicate with higher speed switches by requesting that the
higher speed switch refrains from sending packets. Transmissions are temporarily halted to
prevent buffer overflows.
To display the Flow Control page, click Switching > Ports, and then click the Flow Control link.
