Usage Guidelines
Usage Scenario
The display ip netstream cache origin command and display ipv6 netstream cache origin command display information about original flows in the NetStream flow buffer.
The command can be configured only on a physical system (PS).Precautions
- If no flow with the specified slot ID is specified in the flow buffer, the command output is empty.
- In the local ccc forwarding scenario, if the next hop type cannot be obtained, the next hop in IPv6 flow table and the BGP next hop address is displayed as 0.0.0.0.
- To collect AS number information, you need to specify origin-as or pee-as in the ip/ipv6 netstream export version command.
- For ICMP/ICMPv6 packets, the value of destination-port is calculated based on the values of Type and Code in ICMP/ICMPv6 packets. Specifically, the value of destination-port is Type x 256 + Code.
Example
The actual command output varies according to the device. The command output here is only an example.
