FAQ-How to Check Which Incoming Interface Are Classified IP Packets From

Publication Date:  2012-07-27 Views:  33 Downloads:  0
Issue Description
Q:
How to check which inbound interface are IP packets classified by the NE5000E from? 
 
Alarm Information
Null
Handling Process
 A:
1. In the case of networking with a single NE5000E, enable the path tracing function under all outbound interfaces by running the path-trace enable command. Write the inbound interface information into the source MAC address of the outgoing packets by the corresponding algorithm.
2. In the case of networking with multiple routers, whose inbound interfaces are in the same position (if boards in the same position cannot be adjusted, you need to distinguish which port of which router are the packets from), you can configure different ACL rules and rule numbers on different equipment and enable the ACL rule matching standard. Run the acl-rule-index enable command under the port group and write the matched ACL rules into the source MAC address of the outgoing packets.
3. You can enable the path tracing function and ACL label at the same time or enable just one as required. In the latter case, the 29 (13+16) bits in the last part of the MAC address should all be 0 such as 14 01 A0 00 00 00.
