Re: [SNMP4J] VLANs
Dear Chaim, My suggestion would be. Put the IP Address in some property file. then do the following ResourceBundle msgBundle = ResourceBundle.getBundle(propertyFile_PATH); String nic_ip=msgBundle.getString(SPECIFIED_NIC_IP); InetAddress inetAddress= InetAddress.getByName(nic_ip); UdpAddress udp=new UdpAddress(inetAddress,0); TransportMapping transport = new DefaultUdpTransportMapping(udp); Snmp snmp = new Snmp(transport); Thanks Regards keepFaith, Jaikar Gupta On Tue, Nov 9, 2010 at 12:38 PM, Chaim Turkel - HQ cha...@gilat.com wrote: I need to add support for Vlans.

Hello,
I am trying to write a simple snmp manager that listens to traps on port
162
and processes them. This manager will only handle traps, and does not need
to send commands to agents.
Attached is the code I wrote. It is straightforward, but it does not work -
I do not get any snmp traps.
I make sure that the snmp agent really constantly generates traps, by using
a network sniffer, so my
problem is not lack of traps on the agent side. I am probably doing
something wrong.
Can anyone please help me?
Thanks,
Tsiyona

One can get it by using below code in public void processPdu(CommandResponderEvent e) method:- UdpAddress udpHostAdress = (UdpAddress) e.getStateReference().getAddress(); Thanks Regards Jaikar Gupta On Sat, May 29, 2010 at 10:48 AM, Prakash Kolandaivelu visitprakashin...@gmail.com wrote: If you know answer you can post here , it may be helpful for other people who are looking for the answers.
