NETGEAR AV Line M4250 GSM4210PX 8-Port Gigabit PoE+ Compliant Managed AV Switch with SFP (220W) - Manual (Page 296)

The default is Enable.
12. To change the speed for the port, from the Speed menu, select one of the following
speeds:
• Auto: The speed is set by the auto-negotiation process. This is the default setting.
• 100: The speed is limited to 100 Mbits/second.
The delimiter characters for setting different speed values are a comma (,), a period
(.) and a space ( ). For you to set the auto-negotiation speed, the auto-negotiation
mode selection must be Enable.
Note: You can set the speed for Ethernet ports. For SFP ports, the speed is
automatically detected and you cannot change it.
13. To change the duplex mode for the port, from the Duplex Mode menu, select one
of the following values are as follows:
• Auto: The duplex mode is set by the auto-negotiation process. This is the default
setting.
• Full: Transmission between the devices occurs in both directions simultaneously.
• Half: Transmission between the devices occurs in only one direction at a time.
14. From the Link Trap menu, select to enable or disable the option to send a trap when
the port or LAG link status changes.
For ports, the default is Enable. For LAGs, the default is Disable.
15. In the Frame Size field, specify the maximum Ethernet frame size that the port or
LAG supports, including the Ethernet header, CRC, and payload.
The range is from 1500 to 12270. The default is 9198.
16. In the Debounce Time field, specify the wait period for port or LAG debouncing.
Specify the period as a multiple of 100 milliseconds (msec) in the range from 100
to 5000. The default is 0 seconds, which means that debouncing is disabled.
17. From the Flow Control menu, select the configuration for IEEE 802.3x flow control
for the port:
• Disable: If the port buffers become full, the switch does not send pause frames,
and data loss could occur. This is the default setting.
• Symmetric: If the port buffers become full, the switch sends pause frames to stop
traffic.
Flow control helps to prevent data loss when the port cannot keep up with the
number of frames being switched. When you enable flow control, the switch can
send a pause frame to stop traffic on the port if the amount of memory used by
the packets on the port exceeds a preconfigured threshold and responds to pause
