The Configuration of NetStream Did Not Take Effect Because the Sampling Rate Was not Configured on the NE5000E

Publication Date:  2012-07-27 Views:  126 Downloads:  0
Issue Description
The NetStream function was configured on the NE5000E, but there was no sampling data.
The configuration was as follows:
ip netstream export source
ip netstream export host 50040
interface pos 1/0/0
ip address 221.***.***.238
ip netstream inbound 
Alarm Information
<NE5000E_1>dis ip netstream cache
The cache is empty
Show information of cache is starting.
Show information of cache is end. 
Handling Process
1. The engineer found that the NetStream board was inserted into slot 16. Usually, it is not recommended to insert the NetStream board into slot 16 due to the technical requirement of the hardware.
2. The engineer found that the NetStream board was registered normally. Checking the version of the NetStream board, the engineer found that BootRom was not upgraded. After the upgrade of BootRom, the fault still existed.
3. After the ip netstream sampler random-packets 3000 inbound command was configured, data could still not be sampled. After the ip netstream sampler fix-packets 3000 inbound command was configured, sampling was performed successfully with the outputs of sampling data. The problem was fixed. 
Root Cause
1. The NetStream board was not configured.
2. The NetStream board was abnormal.
3. The configuration was incorrect. 
1. Upgrade BootRom when the NetStream board is added.
2. You must configure the sampling rate on the NE5000E so that the sampling function is enabled.
3. Currently, the NE5000E supports only the fix-packets sampling mode. The optional parameters for three other sampling modes are not shielded, but are not supported. Although the three sampling modes are configured, the sampling cannot be performed.
