Hi Jim,
I appreciate your response. I researched and test it more. I think a have it
resolve it. I do not see "LISTEN" state listed, but I think it will work.
/etc/sysconfig/selinux
SELINUX=disabled
/etc/snmp/snmpd.conf
smuxsocket 1.0.0.0
snmpset -v 2c udp:my.ip.address.xxx:161 sysUpTime.0
snmpd udp:0.0.0.0:161
agentAddress udp:my.ip.address.xxx:161
rocommunity public my.ip.address.xxx 0
/etc/sysconfig/snmpd
OPTIONS="-Lsd -Lf /dev/null -p /var/run/snmpd.pid -a -I
-smux,-smuxsocket,-smuxpeer -x my.ip.address.xxx:161"
# netstat -tulpn | grep snmpd
udp 0 0 my.ip.address.xxx:161 0.0.0.0:*

Does your snmdp.conf use 'agentaddress udp:161' to set the listening port?
Having snmpd also listening on TCP 161 is mostly benign, but it looks like you
don't have the correct option set.

Hi,
I have RHEL 7.2, CentOS 7.x and SUSE 11.x and all of them have the same problem
with the SNMP protocol.
I need to make the SNMP talk UDP:161 and turn down the TCP:199.
# netstat -tulpn | grep snmp
tcp 0 0 0.0.0.0:161 0.0.0.0:* LISTEN 18702/snmpd
tcp 0 0 127.0.0.1:199 0.0.0.0:* LISTEN 18702/snmpd
udp 0 0 0.0.0.0:161 0.0.0.0:* 18702/snmpd
-------------------------------------------------------------------------------------------------------
Troubleshoot so far...
/etc/services
#snmp 161/tcp
# Simple Net Mgmt Proto
#smux 199/tcp
# SNMP Unix Multiplexer
#smux 199/udp
/etc/sysconfig/snmpd
OPTIONS="-Lsd -Lf /dev/null -p /var/run/snmpd.pid -a -I
-smuxsocket -x :161"
/etc/snmp/snmpd.conf
smuxsocket 1.0.0.0
snmpd udp::161
rocommunity public 172.31.64.0/22
# netstat -lnp | grep snmp
tcp 0 0 0.0.0.0:161 0.0.0.0:*
LISTEN 3901/snmpd
udp 0 0 0.0.0.0:161 0.0.0.0:*
3901/snmpd
