Chapter 1 Overview
The Gigabit Managed Switch supports a simple user management function allowing only one administrator to configure the system at the same time. If there are two or more users using an administrator’s identity, it will only allow the one who logs in first to configure the system. The rest of the users, even with an administrator’s identity, can only monitor the system. Those who have no administrator’s identity can only monitor the system. There is a maximum of three users able to login simultaneously in the Gigabit Managed Switch

Daylight Savings Time Set Offset Daylight savings time is used in some countries. If you select this setting, the unit will adjust the time, forward or backward in increments of one hour, between the starting date and the ending date that you select. For example, if you set the daylight savings offset to be 1 hour, when the time reaches the starting time, the system time will be increased one hour. And when the time reaches the ending time, the system time will be decreased one hour

This section describes how to configure Access Control List rule. An Access Control List ACL is a sequential list of permit or deny conditions that apply to IP addresses, MAC addresses, or other more specific criteria. This switch tests ingress packets against the conditions in an ACL one by one. A packet will be accepted as soon as it matches a permit rule, or dropped as soon as it matches a deny rule. If no rules match, the frame is accepted. Other actions can also be invoked when a matching packet is found, including rate limiting, copying matching packets to another port or to the system log, or shutting down a port

The IP and Mask are in the format x.y.z.w where x, y, z, and w are decimal numbers between 0 and 255. When the Mask is converted to a 32-bit binary string and read from left to right, all bits following the first zero must also be zero

Chapter 4 Security
When the NAS module uses the Port Security module to secure MAC addresses, the Port Security module needs to check for activity on the MAC address in question at regular intervals and free resources if no activity is seen within a given period of time. This parameter controls exactly this period and can be set to a number between 10 and 1,000,000 seconds

Multi 802.1X In port-based 802.1X authentication, once a supplicant is successfully authenticated on a port, the whole port is opened for network traffic. This allows other clients connected to the port for instance through a hub to piggyback on the successfully authenticated client and get network access even though they really arent authenticated. To overcome this security breach, use the Multi 802.1X variant

RADIUS-Assigned QoS Enabled When RADIUS-Assigned QoS is both globally enabled and enabled checked on a given port, the switch reacts to QoS Class information carried in the RADIUS Access-Accept packet transmitted by the RADIUS server when a supplicant is successfully authenticated. If present and valid, traffic received on the supplicants port will be classified to the given QoS Class. If re-authentication fails or the RADIUS Access-Accept packet no longer carries a QoS Class or its invalid, or the supplicant is otherwise no longer present on the port, the ports QoS Class is immediately reverted to the original QoS Class which may be changed by the administrator in the meanwhile without affecting the RADIUS assigned

Chapter 4 Security
This section shows the MAC addresses secured by the Port Security module. Port Security is a module with no direct configuration. Configuration comes indirectly from other modules, including the user modules. When a user module has enabled port security on a port, the port is set up for software-based learning. In this mode, frames from unknown MAC addresses are passed on to the port security module, which in turn asks all user modules whether to allow this new MAC address to forward or block it. For a MAC address to be set in the forwarding state, all enabled user modules must unanimously agree on allowing the MAC address to forward. If only one chooses to block it, it will be blocked until that user module decides otherwise

UDP provides two services not provided by the IP layer. It provides port numbers to help distinguish different user requests and, optionally, a checksum capability to verify that the data arrived intact. Common network applications that use UDP include the Domain Name System DNS, streaming media applications such as IPTV, Voice over IP VoIP, and Trivial File Transfer Protocol TFTP
