On the TSM management page , there has the option of active IP address and standby IP address when we add hardware SACG, which scene does we use the standby IP address ？ How to fill IP address out when the SACG connects active switch and standby switch at the same time?
When we add hardware SACG on the TSM management page, we need configure the address of SACG, there are two options of active IP and standby IP. If client has two firewall to do SACG by the mode of loading(not the mode of active and standby), it need input active IP address and standby IP address at the same time. Note :if it is the mode of active and standby, we need only input the active IP address (virtual IP address).
A sort of scene: one SACG connects two switches at the same time, the two switch are the mode of active and standby, when we fill in the address, if we only fill in the interface address which connects the active switch, when the interface appears sunddenness situation(such as DOWN), it may appear the situation of disconnecting SACG. The solution: configure Loopback address and put it out on the SACG, make the address fill in the active IP address of SACG, in this way ,no matter which interface of SACG has some problem, it can reach by the other interface to avoid the situation of disconnecting SACG
