What the smux
We’ve been running into issues where Dell Openmanage doesn’t want to allow snmp in to it’s service in order to gather information. This is normally done via smux which is setup in the snmpd.conf
# Allow Systems Management Data Engine SNMP to connect to snmpd using SMUX
smuxpeer .1.3.6.1.4.1.674.10892.1
What I’ve come to find out is that one some of our servers the smux password has been set to something strange. In order to fix this you need to make a call to the Dell utility dcecfg. For or servers it was one of two calls
/opt/dell/srvadmin/dataeng/bin/dcecfg32 command=setsmuxpassword password=/opt/dell/srvadmin/sbin/dcecfg command=setsmuxpassword password=
After that you need to restart the snmp services:
srvadmin-services.sh restart
/etc/init.d/snmpd restart
And you should be golden. The best way to test is to make an snmp call to the Dell Mibs
snmpwalk -v2c -c <your community> -On <your server> .1.3.6.1.4.1.674.10892.1
