A sniffer tool is used to capture some SNMP messages querying for its UDP group. Compose a data frame (Similar to Figure 5.17) for SNMP PDU types: Get Request from the manager to the agent (noc1 noc2) and Get Response from the agent to the manager (noc2 noc1) based on the followings:
|
Version |
0 |
|
Community |
Public |
|
Request ID |
200 |
|
sysUpTime |
2,000,000 |
|
udplnDatagrams |
50,000 datagrams |
|
udpNoPortS |
5,000 datagrams |
|
udplnErrors |
3000 datagrams |
|
udpOutDatagrams |
25,000 datagrams |
First we need to connect with below address and will check how connectivity will happens
13:55:47.445936 noc1.btc.gatech.edu.164 > noc2.btc.gatech.edu.snmp:
Community = public (As specified)
GetRequest(111) ( we are requesting)
Request ID = 200 ( Request ID will be created)
Below are address which will be generated for above request
system.sysUpTime.0
udp.udplnDatagrams.0
udp.udpNoPortS.0
udp.udplnErrors.0
udp.udpOutDatagrams.0
Get Request from the manager to the agent (noc1 noc2)
Same as above we have made request , here we will wait for response
13:55:47.455936 noc2.btc.gatech.edu.snmp > noc1.btc.gatech.edu.164:
Community = public (Same as above
GetResponse(172) ( response is generated with specified ID
Request ID = 200
system.sysUpTime.0 = 2000000
udp.udplnDatagrams.0=50000
udp.udpNoPortS.0=5000
udp.udplnErrors.0=3000
udp.udpOutDatagrams.0=25000
Get Response from the agent to the manager (noc2 noc1)
