Defining System Information
1. Open the System Description page.
2. Define the following fields: System Name, System Contact, and System Location.
3. If the SNTP Time has synchronized, you can click the Synchronize system time with NTP time to apply the
SNTP time to system time
4. Click Submit.
The system parameters are applied, and the device is updated.
Switch Configuration
From the Switch Configuration page, you can control the IEEE 802.3x flow control mode for the switch.
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 can lead to high-priority and/or network
control traffic loss. When 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 display the Switch Configuration page, click LAN > Administration > Switch Configuration in the navigation
tree.
Figure 8: Switch Configuration
Note: If you want the switch to retain the new values across a power cycle, you must perform a
configuration save, but the System Time does not need a save to retain the new values across a
power cycle.

Field Description
IEEE 802.3x Flow
Control Mode
Enables or disables IEEE 802.3x flow control on the system. The factory default is
disabled.
• Enable: Enables flow control so that the switch can communicate with higher
speed switches.
• Disable: Disables flow control so that the switch does not send pause packets if
the port buffers become full.
