ProSAFE FS526Tv2, FS726Tv2, and FS728TLP Smart Switches Setting Description Maximum Frame The maximum Ethernet frame size (which includes the Ethernet header, payload, Size (1518 To 9216) and CRC) or jumbo size that the port can support. Enter a value in the range of 1518 (Must be even) to 9216 bytes. The default size is 1518 bytes. MAC Address This is a nonconfigurable field that shows the MAC address of the port. PortList Bit Offset This is a nonconfigurable field that shows the bit offset value that corresponds to the port when SNMP uses the MIB object type PortList. ifindex This is a nonconfigurable field that shows the interface index (ifIndex) value that is associated with the port. 5. Click the Apply button. The settings are saved. Enable Flow Control 802.3X flow control is a method to control congestion. When 802.3X flow control is enabled and congestion occurs, the congested port sends a pause frame to the other end of the link to pause the transmission of packets. When congestion is relieved, the port that was congested sends another pause frame to restore the transmission of packets. When congestion occurs, traffic might be dropped for small bursts of time, which can lead to loss of high-priority traffic, network control traffic, or both. When flow control is enabled, switches that function at lower speeds can communicate with switches that function at higher speeds by requesting that the latter refrain from sending packets. When such a situation occurs, transmissions are temporarily halted to prevent buffer overflows.  To enable global flow control: 1. Select Switching > Ports > Flow Control. The Flow Control screen displays. 2. Next to Global Flow Control (IEEE 802.3x) Mode, select the Enable radio button. By default, the Disable radio button is selected, and global flow control is disabled. Configure Ports 64
