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
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.
Jumbo frames support packets of up to 9 Kilobytes in size. If jumbo frames are not enabled
(default), the system supports packet size up to 2048 bytes. For jumbo frames to take effect,
the switch must be rebooted after the feature is enabled.
To configure global configuration settings:

1. Select Switching
The following screen displays:
2. Next to Global Flow Control (IEEE 802.3x) Mode, enable or disable IEEE 802.3x flow control
on the system. The factory default is Disable.
