Flow Control, Maximum Frame Size

Page 82 highlights

GS716Tv3, GS724Tv4, and GS748Tv5 Smart Switches • Link Trap. Select 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. The size includes the Ethernet header, CRC, and payload. Any change to the maximum frame size is immediately applied to all interfaces. • MAC Address. The physical address of the specified interface. • PortList Bit Offset. The bit offset value that 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. 4. Click the Apply button. 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 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 configure global flow control settings: 1. Select Switching > Ports > Flow Control. 2. Next to Global Flow Control (IEEE 802.3x) Mode, enable or disable IEEE 802.3x flow control on the system. • Enable. The switch sends pause packets if the port buffers become full. • Disable. The switch does not send pause packets if the port buffers become full. 3. Click the Apply button. Configuring Switching 82

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.
