Hello all,

The current network topology is as follows. S5310 and S9312 need to communicate with each other. If the S9312 and S5310 are connected to a physical line, will a loop occur? How to handle the interworking problem.

Current network: S10508 and S5310 can be accessed. The firewall is a video firewall that is used for IP address translation. In transparent mode, no policy is available.

Hello,

The first problem: for the current environment, first check whether the direct connection between the corresponding devices is accessible, and then check whether the route is accessible. If there is a firewall, check whether the firewall releases the corresponding security policy.


The second problem: 9312 and 5310 of an indirect line, such as the firewall is three layers, that generally will not have a loop, such as a firewall is two layers, then there may be a loop.

Hope to help you!
