MAC Filtering
Customization
Login Failures
Working Mode
To add a MAC filter:
1. Click Add. A dialog box similar to the one below appears:
The Customization page is grouped into three sections: Login Failure,
Working Mode, and Miscellaneous.
• The Allowed field sets the number of consecutive failed login attempts that are permitted from a remote computer before that user is timed out.
• The Timeout field sets the amount of time a remote computer must wait before attempting to login again after it has exceeded the maximum
number of allowed login failures.
• Selecting the Enable ICMP option will allow the B064-Series KVM Switch to be pinged. It also allows an IP address to be assigned via the
ARP command. If it is not enabled, the device cannot be pinged, nor can it be assigned an IP address with the ARP command. It is enabled by
default.
• Selecting the Enable Browser option will allow the B064-Series KVM Switch to be remotely accessed via web browser. If browser access is
not enabled, users will not be able to log into the unit with a browser. It is enabled by default.
• Selecting the Enable Multiuser Operation option permits more than one user to log into the B064-Series KVM Switch at the same time. It is
enabled by default.
• Selecting the Force all to grayscale option forces the remote displays of all devices connected to the B064-Series KVM Switch to be displayed
in grayscale. This can speed up transfer time in low bandwidth situations, which can improve keyboard and mouse response time.

2. Type in the desired MAC address and click OK.
3. Repeat these steps for any additional MAC addresses you want to
filter.
To delete a MAC filter:
Select the desired MAC filter from the list and click Remove.
To modify a MAC filter:
1. Select the desired MAC filter from the list and click Edit. An Edit
dialog box box appears.
2. Delete the old address and replace it with the new one. Click OK.
Note: To block a computer from accessing the B064-Series KVM
Switch, you do not need to filter both its IP address and its MAC
address. Any computer blocked by a MAC filter will be denied access
to the KVM switch, even if the computer is allowed to access the
KVM switch under the IP filters that are set up.
If any filters have been configured, they appear in the IP Filter and/or
MAC Filter list boxes.
