Configuring Switching

 S3300 Smart Managed Pro Switch
and 1000 Mbps) will be advertised. Otherwise, your selection will determine the 
port’s duplex mode and transmission rate. The factory default is Auto.
- 10 — 10 Mbits/sec.
- 100 — 100 Mbits/sec.
- 10G — 10 Gbits/sec.
The delimiter characters for setting different speed values is ',', '.' and space. You 
must set Auto-negotiation mode to Enable in order for you to be able to set the 
auto-negotiation speeds.
Note: After changing the Speed mode, the switch may be inaccessible for 
some seconds due to applying new settings.
• Duplex Mode. Specify the duplex mode for this port. Possible values are:
- 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.
- Auto. Set by auto-negotiation process.
Note: After changing Duplex mode, the switch may be inaccessible for 
some seconds due to applying new settings.
• Link Trap. Select whether or not to send a trap when link status changes. The factory 
default is enabled for normal interfaces and disabled for LAG interfaces. Possible 
values are: 
- 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. Valid values are 1500 to 9198. The default value is 1500. The size includes 
the Ethernet header, CRC, and payload. Any change to the maximum frame size is 
immediately applied to all interfaces. 
• Flow Control. Specify the IEEE 802.3x flow control mode for this port from the 
following options:
- Disable flow control. Flow control helps to prevent data loss when the port cannot 
keep up with the amount 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 
packets on the port exceeds a preconfigured threshold, and will respond 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
