In the V1R22C00 version of CloudCampus solution, the description of the FW synchronization IP-Group feature is incorrect ()

NCE-Campus supports the configuration of firewall security group policies.

When a user passes the NCE-Campus authentication or the permission changes, NCE-Campus synchronizes the user name, IP-group, and IP address information to FW, and FW identifies all user groups based on the mapping relationship between IP address, user name, and IP-group, and executes the corresponding security group policy.

Reuse the current online behavior management process, and add lP-Group information to the synchronization information of NCE-Campus and firewall.

When the user goes online and ages in FW, FW actively queries the online user to the NCE-Campus server to keep the IP-Group and other information at both ends synchronized

In the LAN-WAN convergence scenario, the description of RR deployment design principles is wrong ()

Try to choose an independent RR, which can be deployed on a single device in the independent RR scenario.

The Edge should be dual-uplink to the two RR devices to achieve egress backup;

In the campus scenario, the correct policy linkage function is ()

In the policy linkage scenario, you need to set the downstream port type of the Edge device to Extended Access Switch

When the authentication point and the group policy execution point are not on the same device, you need to use the policy linkage function.

In the policy linkage scenario, you need to set the downstream port type of the Edge device to Extended Access Switch

The policy linkage function means that no matter where you go, the permission to access resources is the same, and it is decoupled from the IP address.

When the authentication point, access point, and group policy execution point are all connected to the device, the policy linkage function should be used
