Does the VP9660 MCU support service board backup?
The VP9660 MCU supports service board backup. 1. The VP9660 has multiple slots for housing service boards; therefore, multiple service boards can be configured to implement signaling or media backup and switchover. 2. After the system starts, it selects one service board as the H.323 signaling processing board. If this board is faulty, the system automatically switches the signaling service to another service board. If you remove a media board that is in use, services on the board will be automatically switched to another available media board.

What are the types of primary and backup interfaces supported by interface backup
Primary interfaces: Ethernet Layer 3 interface and subinterface, dialer interface, ATM interface, ISDN BRI interface, Async interface, cellular interface, PON interface, MP-group interface, MFR interface, FR subinterface, and serial interface and subinterface. Backup interfaces: Ethernet Layer 3 interface and subinterface, dialer interface, ATM interface, BRI interface, Async interface, cellular interface, MP-group interface, MFR interface and subinterface, and serial interface and subinterface. On the AR120&AR150&AR160&AR200 device, primary and backup interfaces cannot be ISDN BRI interfaces, PON interfaces, or Async interfaces.

Problem and solution when TCP services are interrupted intermittently when fast backup is enabled on the USG and incoming and outgoing packets are forwarded by active and standby USGs?
If the TCP SYN packet passes through one firewall in hot standby networking and the SYN-ACK packet through the other one but the session table is not yet backed up, the packet is discarded due to status error. When incoming and outgoing packet paths are different and the traffic is relatively heavy, certain services may be interrupted intermittently due to backup delay. If this exerts severe impacts on services, disable link status check.
