Question !!!
Hello,
I am a network engineer. I wll like to implement netflow analyzer to analysis our WAN traffic. I have some question need to you answer.
1. Scope : 2 GSR router with 4 STM1 link and 8 sets 76xx and 72xx router for DS3 and serial circuit.
2. Requirment: keep 1 month raw data and 50 interfaces licence
3. Flow Rate in the past 32 Hours : 2,164 per second (About 80% loading in our test lab)
4. Question:
a. How about storage space and server specification I need. (minimum)
b. Some interfaces only IN traffic. (I found output of show ip cache flow DstIf is Null
c. Some interfaces data traffic not match with SNMP (MRTG). netflow traffic some then SNMP data
d. I need to create multiple listener port for multiple routers.
Your answer will help me to come out my proposal.
