[SNMP4J] Network Discovery

[James Prickett]

I'm trying to programmatically turn off a port on a switch using the SNMP4J library and I'm stuck on the following error:

org.snmp4j.transport.UnsupportedAddressClassException: Unsupported address class (transport mapping): org.snmp4j.smi.IpAddress
	at org.snmp4j.MessageDispatcherImpl.sendPdu(MessageDispatcherImpl.java:413)
	at org.snmp4j.Snmp.sendMessage(Snmp.java:1067)
	at org.snmp4j.Snmp.send(Snmp.java:895)
	at org.snmp4j.Snmp.send(Snmp.java:875)
	at org.snmp4j.Snmp.send(Snmp.java:840)
	at com.force3.snmp.SnmpExample.main(SnmpExample.java:51)

I get the same exception using the TcpAddresss class as well.

Anyone have a clue what I should be using to specify the address?

Regards,
James
