communication between agent and information

[FarhadZadeh]

Hi,
I'mworking on net-snmp-5.2.1 with SuSe-9.2 i have a question about agent ,
assume we have a small network with a manager (A) and an agent(B).
manager(A) send a GetRequest to Agent(B) for example about ip.pForwarding.
0 please tell me the agent how it response to request from manager on the
other hand the agent where and how achieve these information about this
request.

I'm not sure I understand. The agent replies to the pole with a value, in this case the integer value of 1:

# snmpget -v 1 -c public 182.168.1.1 ip.ipForwarding.0
IP-MIB::ipForwarding.0 = INTEGER: forwarding(1)

If you want to see the actual traffic, you can use tcpdump or a sniffer.
