M6100, M5300, and M7100 Series Managed Switches
Note: After you change the speed value, the switch might be inaccessible for
a number of seconds while the new settings take effect.
14. From the Duplex Mode list, select the duplex mode for the selected port.
Possible values are as follows:
• Auto. Indicates that speed is set by the auto-negotiation process.
• Full. Indicates that the interface supports transmission between the devices in both
directions simultaneously.
• Half. Indicates that the interface supports transmission between the devices in only
one direction at a time.
The default is Auto.
Note: After you change the duplex mode, the switch might be inaccessible
for a number of seconds while the new settings take effect.
15. Use the Link Trap object to determine whether to send a trap when link status changes.
The factory default is enabled.
16. Use Frame Size to specify the maximum Ethernet frame size the interface supports or is
configured to use , including Ethernet header, CRC, and payload.
The range is 1518 to 12288. The default maximum frame size is 1518.
17. Use Debounce Time to specify the timer value for port debouncing in a multiple of 100
milliseconds (msec) in the range to 100 to 5000.
The default debounce timer value is 0, which means that debounce is disabled.
18. From the Flow Control list, select to Enable or Disable IEEE 802.3 flow control.
The default is Disable. The switch does not send pause frames if the port buffers become
full. Flow control helps to prevent data loss when the port cannot keep up with the
number of frames being switched. When enabled, the switch can send a pause frame to
stop traffic on a port if the amount of memory used by the packets on the port exceeds a
preconfigured threshold and responds to pause requests from partner devices. The
paused port does not forward packets for the period of time specified in the pause frame.
When the pause frame time elapses, or the utilization returns to a specified low threshold,
the switch enables the port to again transmit frames. For LAG interfaces, flow control
mode is displayed as blank because flow control is not applicable.
19. Click the Apply button.
The switch is updated with the values you entered. For the switch to retain the new
values across a power cycle, you must save the configuration.
