Procedure
Step 1 Set the IP addresses for the interfaces of Switch A and Switch B as shown in
configuration procedure is not mentioned here.
Step 2 Mirror the traffic on Switch B to the SPU.
# Mirror the traffic on GigabitEthernet1/0/0 of Switch B to XGigabitEthernet4/0/0.
<Quidway> system-view
[Quidway] sysname SwitchB
[SwitchB] observe-port 1 interface xgigabitEthernet4/0/0
[SwitchB] interface gigabitethernet1/0/0
[SwitchB-GigabitEthernet1/0/0] port-mirroring to observe-port 1 inbound
Step 3 Enable the NetStream on the SPU to collect traffic statistics on the inbound interface.
# Enable the NetStream on XGigabitEthernet0/0/1 of the SPU to collect traffic statistics on the
inbound interface.
<Quidway> system-view
[Quidway] sysname SPU
[SPU] interface xgigabitethernet0/0/1
[SPU-XGigabitEthernet0/0/1] ip netstream inbound
Step 4 Set the SPU to export statistics to the NSC. You must also configure the source address of the
statistics.
Configure the SPU to export statistics to the NSC with the IP address 10.2.1.2 and UDP port
6000.
[SPU] ip netstream export host 10.2.1.2 6000
Set the source address of the traffic statistics exported by SPU.
[SPU] ip netstream export source 10.2.1.1
Step 5 Set the aging mode and aging time of the original traffic.
# Set the inactive aging time of the original traffic to 100 seconds.
[SPU] ip netstream timeout inactive 100
# Set the aging of the original traffic according to the FIN flag in the TCP packet header.
[SPU] ip netstream tcp-flag enable
Issue 01 (2012-03-15)
Mirror the traffic on Switch B to the SPU.
Enable the NetStream on the SPU to collect statistics about the inbound traffic.
Configure the SPU to export statistics to the NSC and configure the source address of the
statistics.
Set the aging mode and aging time of packets.
IP address of each interface
Address and port number of the NSC and source address contained in the packets
NOTE
The SPU is located in slot 4.
