FAQ-Can the NE80E as the Packet Classifier Re-duplicate the HTTP Traffic to a Port for Output

Publication Date:  2012-07-27 Views:  29 Downloads:  0
Issue Description
Q:
Can the NE80E (VRP5.3 or V500R003) as the traffic splitting platform fulfill the following tasks: to classify the traffic (based on the source IP addresses) flowing through multiple POS interfaces according to the traffic policy so that the traffic is output to the server through multiple GE interfaces?
When a server is added, you need to analyze all the traffic related to the HTTP services. Can the traffic splitting platform duplicate such traffic at the inbound interface and then output the duplicated traffic to the new server from other GE interfaces without affecting the original current dividing policy?
In the current configuration, the policy is to match the ACL rules, which are all similar to rule 1 permit source 61.131.128.0 0.0.0.255.

Handling Process
 A:
1. Roadmap: With the duplication group function, the HTTP traffic can be duplicated to two ports, one as the outbound interface of the traffic, connected to the new server, and the other for the traffic loopback of the traffic. Then the loopback traffic is redirected to the same port group.
Example:
Original configuration
Incoming interface P1/0/0 ? matching ACL 3000 ? redirect the traffic to the outbound interfaces G2/0/0 and G2/0/1
New configuration:
Incoming interface P1/0/0 ?matching HTTP ? duplicate the traffic to the outbound interfaces G3/0/0 (connected with the new server) and G3/0/1 (traffic loopback)
Incoming interface P1/0/0 ? matching ACL 3000 ? redirect the traffic to the outbound interfaces G2/0/0 and G2/0/1
Incoming interface G3/0/1 ? matching ACL 3000 ? redirect the traffic to the outbound interfaces G2/0/0 and G2/0/1
2. Note that, in the new configuration, matching HTTP must be prior to ACL 3000 so that all HTTP packets match the rules.
3. In this manner, the original configuration is not affected. Note that a loopback port must be added for each new outbound interface connected with the new server, which is a waste of physical port resources.
