Publication Date:  2013-07-02 Views:  2 Downloads:  0
Issue Description
Does the NIP product support the back and forth path is not consistent and two-node cluster networking?
Alarm Information
None.
Handling Process
1, NIP does not support the networking whose back and forth path is not consistent.
2, NIP only supports primary/secondary mode networking, does not support load balance mode networking.
Root Cause
None.
Suggestions
1, the flow from the internal network to the external network hasn’t passed through NIP equipment, while the flow from external network to internal network has passed through NIP equipment, the back and forth path is not consistent. In most cases, to detect an attack needs to observe both directions flow of the same data flow, but the back and forth path inconsistent will lead to NIP can only observe part of the network flow, it is easy to cause miscarriage of justice. So NIP does not support the networking whose back and forth path is not consistent. When planning deployment NIP products, needs to the situation that the back and forth path is not consistent, otherwise it may cause the result that business is interrupted.

 2, NIP uses management port MGMT as the heartbeat backup channel of the two-node cluster hot backup, two sets of equipment’s management port need through the exchange connecting. Due to the backup data quantity is too much, it is suggested using gigabit switches connect management port (heartbeat port).
