Operation Manual – NAT, Netstream, Policy RoutingH3C S7500 Series Ethernet Switches Chapter 3 Policy Routing Configuration3-1Chapter 3 Policy Routing Configurationz Overviewz Configuring Policy Routingz Displaying Policy Routing Configurationz Policy Routing Configuration ExampleNote:Currently, the LS81VSNP boards installed in S7500 series switches support the policyrouting feature. In this manual, the LS81VSNP board is called LPU.3.1 OverviewComparing with the normal routing mechanism which determines the next hop of apacket by its destination IP address, policy routing provides a more flexible way toachieve the same purpose. You can perform policy routing configuration so that thedevice can use not only destination IP address, but also other information carried inpackets, such as source IP address, source/destination port number, and even protocoltype, to determine the next hops of packets.On S7500 series switches, policy routing is achieved by redirecting packets. You canuse the traffic-redirect commands to redirect the packets that match particular ACLsto specified VLAN interfaces or IP addresses.3.2 Configuring Policy RoutingFollow these steps to configure policy routing:To do… Use the command…Define an ACL aclDefine an ACL rule ruleConfigure inbound packet redirection traffic-redirect inbound ip-groupConfigure outbound packet redirection traffic-redirect outbound ip-groupFor the configuration of ACL, refer to the ACL module in this manual.Follow these steps to configure packet redirection:
