XS728T ProSAFE 28-Port 10-Gigabit L2+ Smart Switch
Ports
The screens you access from the Ports menu allow you to view and monitor the physical port
information for the ports available on the switch. From the Ports menu, you can access the
features described in the following sections:
• Global Configuration
• Port Configuration
Global Configuration
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 action
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 configuration settings:
1. Select Switching > Ports > Global Configuration.
2. Next to Global Flow Control (IEEE 802.3x) Mode, enable or disable IEEE 802.3x flow
control on the system. The 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 to apply the changes to the system.
Port Configuration
Use the Port Configuration screen to configure the physical interfaces on the switch.
To configure port settings:
1. Select Switching > Ports > Port Configuration.
2. Select the interface for which you want to configure settings.
• To configure settings for a physical port, click PORTS.
• To configure settings for a link aggregation group (LAG), click LAGS.
• To configure settings for both physical ports and LAGs, click All.
3. Select the check box next to the port or LAG to configure.
You can select multiple ports and LAGs to apply the same setting to the selected
interfaces. Select the check box in the heading row to apply the same settings to all
interfaces.
4. Configure or view the settings:
