Parameter

Type of Filtering

Meaning

This enables or disables the MAC filtering.

For Static MAC filtering

MAC address This sets the MAC address where the address filter will be added or removed. (Input example: 00:11:22:aa:bb:cc)

To register, select the port to be registered, and click Register.

To remove, select the port where the MAC address is registered, and click Delete.

Notes: · All frames can pass through ports where no MAC address is registered.

· In ports where a MAC address is registered, only frames that have the registered MAC address as the source

MAC address can pass through, and other frames are blocked.

· Frame filtering is performed during input to the port.

· Up to 16 MAC addresses can be registered per port.

· If a MAC filter is set, 802.1x authentication cannot be performed at the port.

For Dynamic MAC filtering

# of MAC This sets the number of devices (0 to 8191) where dynamic MAC address learning is allowed for each port.

Notes: · Ports where the number of setting units is left blank are set to allow all MAC addresses.

· Each port can be set in the range from 0 to 8191, but the switch can learn a maximum of 8191 MAC addresses only. If the number of addresses exceeds 8191, MAC addresses are discarded without learning them.

No operation is performed for the port where a loop was detected.

However, the DIAG LED and LED for the port where the loop was detected both blink, and the buzzer sounds for about 60 seconds. If the loop is detected after 60 seconds, the 60-second buzzer sounds again, and the operation is repeated.

Disable the port:

When a loop is detected in a port, the port is disabled only for the number of seconds that was set in “Disable duration”. At the same time, the DIAG LED and LED for the port where the loop was detected both blink, and the buzzer sounds for the number of seconds set in “Disable for:”.

If “Disable the port “ was set for operation when a loop is detected, this sets the time (seconds) that the port is disabled.

Range: 0 to 65535 seconds

This enables the MAC thrashing system of the loop detection function.

A loop is recognized if the number of learned MAC addresses of this switch exceeds the preset threshold value in 1 second.

This enables the LDF system of the loop detection function.

This sends LDF packets at 1-second intervals. A loop is recognized if the sent LDF packet is received.

This enables the reception rate system of the loop detection function.

A loop is recognized if the preset reception rate is exceeded.

This sets the reception rate threshold value (1 to 1000 Mbps) for recognizing a loop.

• If the time that was set in “Disable duration” has elapsed, the port is automatically enabled.

• The loop detection function temporarily disables a port when a loop is detected. It does not prevent loops. The spanning tree function is used to block the port where the loop was detected; it automatically switches the communication route to prevent a network failure. The Buffalo switch includes both functions. Use the function you need based on your environment.

Chapter 2 Configuration

Parameter

Boot Mode

Auto-save

Meaning

The settings file is read from a USB device when booting.

When the boot settings are set to read from USB, they are read from the “default.cfg” file on the USB device. If there is no ”default.cfg” file on the USB device, the configuration file is read from the switch itself.

When the settings are changed while a USB device is inserted in the device, ”default.cfg” is created on the USB device, and synchronized with the settings on the product. The latest settings file is always saved to ”default.cfg” on the USB device.

”default.cfg” under the root directory of the USB device is loaded upon booting.

A backup of the configuration file is automatically saved to the USB device when the configuration is changed.

If enabled, the settings file is automatically saved to “default.cfg” and “yyyymmdd.cfg” on the USB device whenever configuration changes are made.

The latest version is always saved to “default.cfg”, and the version before the latest settings file is saved to “yyyymmdd.cfg”.

default.cfg:

The latest settings file is synchronized with the product.

yyyymmdd.cfg:

This indicates the date set on the switch. The settings file from before the change in settings is saved as a backup.

Example:

If the settings are changed on October 1, 2012 while Auto-save is enabled, the settings file for after the change in settings is saved to the USB device as “default.cfg“ and the settings file from before the change in settings is saved as “20121001.cfg“ as a backup.

If several changes are made to the settings file on the same day,

“yyyymmdd.cfg“ is overwritten.

“default.cfg“ and “yyyymmdd.cfg“ are saved to the root directory of the USB device.
