SNMP - what am I seeing?

Hey everyone!
First, thank you in advance for any help you can provide. I'm a fairly experienced linux user, and just getting my feet wet in solaris for a project here at the office. I am trying to use snmpget on a linux box to get information from a Solaris 10 system. The solaris 10 system has snmpdx running (solstice, used for SNMP by a vendor solution that is installed). However it also appears to have snmpd running. Here are the commands and output that I get:

bash-3.00# ps -ef |grep snm
    root   775     1   0   Mar 10 ?         345:35 /usr/lib/snmp/brdsftMIB2 -r -c /usr/local/broadworks/bw_base/conf -p 10161

snmpd       755   root   18u  IPv4 0x60002b65900      0t0  UDP *:17

This shows the services running on UDP port 17. The problem is if I try and query remotely on port 17, everything fails. Why does lsof show port 17 and not 161? In fact typing

lsof -i |grep 161

doesn't return a single thing.

Any help would be appreciated. Both daemons show as running, and I'd like to figure out what ports they're running, and then figure out what information is attainable from each daemon. I'm assuming snmpdx is just vendor related stuff, because from my research snmpd should be for OS stuff. Any thoughts?
Thanks!

       agentaddress [:][,...]
	      defines  a  list	of  listening  addresses,  on which to receive
	      incoming SNMP requests.  See the section LISTENING ADDRESSES  in
	      the  snmpd(8)  manual page for more information about the format
	      of listening addresses.

	      The default behaviour is to listen on UDP port 161 on  all  IPv4
	      interfaces.

I appreciate the link, but it still doesn't tell me why I don't see port 161 open anywhere. If the daemon is bound to that port, shouldn't it show up? Why is port 17 showing up?

also: man snmpdx.
you have a 'non-monolithic' SNMP agent with the master/slave(s) paradigm.

Any possibility of putting that into lay terms? I'm still rather new to snmp, let alone solaris. I'm just not sure why the ports are showing something different than what is working - and googling monolithic snmp agent just tells me that monolithic means that the MIBs are compiled into the agent. Are you saying that snmpd is being used by snmpdx?

I am really sorry.

Both man pages show that the daemons are listening on port 161. But shouldn't lsof show 161 open? Does that mean that both daemons are using 161?

Be aware: 161 is just the default. Maybe someone reconfigured to 17 or something such.
