GS752TXS and GS728TXS Smart Switches • 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. Specifies 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. 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. 5. Click Apply. 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. The Flow Control screen displays. 2. Next to Global Flow Control (IEEE 802.3x) Mode, enable or disable IEEE 802.3x flow control on the system. The factory default is Disable. • 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 Apply. 97
