  • Page 32: X-Ring Application

    2.7 X-Ring Application The industrial switch supports the X-Ring protocol that can help the network system recover from network connection failure within 10ms or less and make the network system more reliable. The X-Ring algorithm is similar to Spanning Tree Protocol (STP) and Rapid STP (RSTP) algorithm but its recovery time is less than STP/RSTP.

  • Page 33: Coupling Ring Application

    2.8 Coupling Ring Application As the illustration shown below, users can use the X-Ring groups to form a coupling ring for redundant backup. It can ensure the transmissions between X-Ring groups not to fail. The following figure is a sample of coupling ring application. Note The Ethernet switches with firmware version before v3.0 use the X-Ring function that has the limitations as follows.

  • Page 34: Dual Homing Application

    2.9 Dual Homing Application The Dual Homing function is to prevent the connection loss between the particular X- Ring group and the upper level/core switch. Assign one port, and only one, to be the Dual Homing port that is the backup port in each single X-Ring group. The Dual Homing function only works when the X-Ring function is active.

If the port-based VLAN enabled, the VLAN-tagging is ignored. In order for an end station to send packets to different VLAN groups, it itself has to be either capable of tagging packets it sends with VLAN tags or attached to a VLAN-aware bridge that is capable of classifying and tagging the packet with different VLAN ID based on not only default PVID but also other information about the packet, such as the protocol.

  • Page 94 IGMP Configuration The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP) suite. IP manages multicast traffic by using switches, routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect IGMP queries, report packets, and manage IP multicast traffic through the switch.
  • Page 95 X-Ring X-Ring provides a faster redundant recovery than Spanning Tree topology. The action is similar to STP or RSTP, but the algorithms between them are not the same. In the X-Ring topology, each switch should be enabled with the X-Ring function and two ports of each switch should be configured as the member ports in the ring.
  • Page 96 Figure 3.4-44 X-ring Interface Note When the X-Ring function enabled, the user must disable the RSTP. The X- Ring function and RSTP function cannot exist on a switch at the same time. Remember to execute the “Save Configuration” action, otherwise the new configuration will lose when switch powers off.
  • Page 97 3.3.4 Security In this section, you can configure 802.1x and MAC address table. 802.1X/Radius Configuration 802.1x is an IEEE authentication specification which prevents the client from connecting to a wireless access point or wired switch until it provides authority, like the user name and password that are verified by an authentication server (such as RADIUS server).
  • Page 98 802.1x/Radius—Port Configuration You can configure the 802.1x authentication state for each port. The state provides Disable, Accept, Reject, and Authorize. • Reject: The specified port is required to be held in the unauthorized state. • Accept: The specified port is required to be held in the Authorized state. •...
  • Page 99 802.1X/Radius - Misc Configuration • Quiet Period: Set the period which the port doesn’t try to acquire a supplicant. • TX Period: Set the period the port waits for retransmit next EAPOL PDU during an authentication session. • Supplicant Timeout: Set the period of time the switch waits for a supplicant response to an EAP request.
  • Page 100 MAC Address Table Use the MAC address table to ensure the port security. You can add a static MAC address; it remains in the switch's address table, regardless of whether the device is physically connected to the switch. This saves the switch from having to re-learn a device's MAC address when the disconnected or powered-off device is active on the network again.
  • Page 101 MAC Address Table - MAC Filtering By filtering MAC address, the switch can easily filter the pre-configured MAC address and reduce the un- safety. You can add and delete filtering MAC address. Figure 3.4-49 MAC Filtering interface • MAC Address: Enter the MAC address that you want to filter. •...
