Doesn't work for me, the grep command removes *:* entry from the output:

root at gw1 [/root]# netstat -an
Active Internet connections (including servers)
Proto Recv-Q Send-Q  Local Address          Foreign Address        (state)
udp4       0      0 127.0.0.1.161          *.*
udp4       0      0 *.*                    *.*
<snip>

The 127.0.0.1 entry is added with
"begemotSnmpdPortStatus.127.0.0.1.161 = 1", but the other entry is
always there. Turn the daemon on and off to verify that it's bsnmpd
(or use sockstat).
