Configuring the GFGUB/GOGUB

This describes how to add a GFGUB/GOGUB in the GMPS/GEPS and configure its attributes. The GFGUB/GOGUB is responsible for the IP transmission on the Abis interface.

Prerequisite

The GMPS/GEPS has idle slots to hold the GFGUB/GOGUB.

NOTE:

When the GFGUB/GOGUB is used to implement the Abis over IP mode, the device IP address and the port IP address must be configured. The device IP address and the port IP address can implement end-to-end communication separately.

You can choose the port IP address or device IP address for communication on the Software Parameter tab page of BSC Attributes.

BSC ABIS MUX is optional. It is configured when the ABIS MUX is used to improve the IP transmission efficiency on the Abis interface. The ABIS MUX function is available for use only when the BTS in IP transmission mode is configured on the GFGUB, the PTU on this BTS is configured with the BTS ABIS MUX function, and the BSC ABIS MUX function is configured on the GFGUB.

When the BSC is configured with two GFGUB/GOGUBs, you can set Net Mode to Inter-Board Active/Standby or Inter-Board load sharing to improve networking reliability. When the BSC is configured with only one GFGUB/GOGUB (Independent mode), you can configure routes to guarantee networking reliability.

In active/standby mode, the IP addresses of related ports must be configured on the same network segment. In load sharing mode, if the BSC performs communication through device IP addresses, then the two boards for load sharing must use the same device IP address. Regardless of whether device IP addresses or port IP addresses are used for communication, port IP addresses must be on different network segments.

Besides the configuration of the networking mode, you can configure BFD link detection and ARP link detection to improve system reliability. You can either ARP link detection or BFD link detection on one port. ARP link detection is available when NEs at one end of the ARP link support the ARP link detection. BFD link detection, however, is available only when NEs at both ends of the BFD link support the BFD link detection.

Procedure

1. Add a board.
   1. On the BSC6000 Local Maintenance Terminal, click the BSC Device Panel tab. Select a cabinet number from the Current Cabinet drop-down list.
   2. Right-click an idle slot among slots 18-27 holding the GMPS, and then choose Add Board from the shortcut menu. A dialog box is displayed, as shown in Figure 1.
      Figure 1 Add Board dialog box
      
      

   3. Set FuncType to Abis interface board, and set Board Type to GFGUB. Then, set other parameters by referring to Table 1.
      NOTE:

      When Net Mode is set to Inter-board load sharing, you are not allowed to configure a logical port.

   4. Click Finish. The addition of the GFGUB is complete.
2. Configure the board attributes.
   1. Right-click GFGUB, and then choose Configure Board Attributes from the shortcut menu. A dialog box is displayed, as shown in Figure 4.
      Figure 2 Configure Board Attributes dialog box (GFGUB)
      
      

   2. Set Load Key, and then click Next. A dialog box is displayed, as shown in Figure 3.
      Figure 3 Configure Board Attributes dialog box (Ethernet port)
      
      

   3. Set the attributes of the Ethernet port by referring to Table 1.
      NOTE:

      When you modify the attributes of a port on the GFGUB, the port becomes faulty temporarily. If the board is in active/standby mode, an active/standby switchover is performed automatically.

   4. Click Next. A dialog box is displayed, as shown in Figure 4.

   3. Set the parameters by referring to Table 1. Click OK to return to the dialog box, as shown in Figure 5.
      NOTE:

      A device IP address is the IP address for implementing communication. This IP address is valid for the IP addresses of all the ports of the board. The device IP addresses for the interface boards operating in active/standby mode are the same. The IP addresses for the interface boards not operating in active/standby mode should not be arranged on the same network segment.

   4. Click Finish. The configuration of the device IP address is complete.
4. Configure the port IP address.
   1. Right-click GFGUB, and then choose Configure Ethernet Port IP from the shortcut menu. A dialog box is displayed, as shown in Figure 7.

      Figure 8 Add Ethernet Port Ip dialog box
      
      

   3. Set the parameters by referring to Table 1. Click OK to return to the dialog box, as shown in Figure 7.
      NOTE:

      • One Ethernet port supports multiple IP addresses. That is, one Port No. can be configured with multiple Ip Address. The IP addresses of different IP Address Index for the same port must be located on different network segments. In addition, these network segments cannot have common parts.
      • IP Address Index of a port is calculated automatically and not user-defined.
      • For multiple IP addresses over one port, you must delete IP addresses with caution and cannot delete IP addresses in use.
      • If Port Type is set to FE, one board can be configured with eight port IP addresses on different network segments. If Port Type is set to GE, one board can be configured with two port IP addresses on different network segments.
      • The port IP address and the device IP address must be configured on different network segments. The port IP addresses for the active and standby GFGUBs must be configured on the same network segment.

   4. Click Finish. The configuration of the port IP address is complete.

        NOTE:

        • BFD detection and ARP link detection cannot be enabled at the same time.
        • One port can be configured with only one detection mode. When a port is not configured with BFD detection or ARP link detection, physical layer detection is performed.
        • Currently, you can configure detection modes in the following ways: BFD detection for both the active and standby ports, ARP link detection for both the active and standby ports, BFD detection for the active port and physical layer detection for the standby port, ARP link detection for the active port and physical layer detection for the standby port, and physical layer detection for both the active and standby ports.

        NOTE:

        • The selected Port No. must be configured with the port IP address.
        • Peer IP must be different from the device IP address and the port IP address, and must be on the same network segment as the port IP address.
        • In active/standby mode, Peer IP Address of the Standby Board can be configured and must be located on the same network segment as the corresponding port IP address.
