suppress known warning message


When snmpd is started, a warning will appear.
How to suppress this known warning message, i.e. other warning message will still appear.
# /sbin/service snmpd start > /dev/null
WARNING: initlog is deprecated and will be removed in a future release

If I do this, I am afraid all other warning messages (if any in the future) will be suppressed:
#/sbin/service snmpd start >& /dev/null

Code:
v1=`/sbin/service snmpd start > /dev/null`
v2=`echo $v1|grep known_err`
if [[ $? -ne 0 ]]
then
    echo "New error"
fi

Thanks, but it does not work.
I add some echo statements.

Code:
known_err="WARNING"
v1=`/sbin/service snmpd start > /dev/null`
v2=`echo $v1|grep known_err`
v3=`echo $v1|grep $known_err`
echo "v1 $v1 v2 $v2 v3 $v3"
v4=`echo $v1|grep $known_err`
if [[ $? -ne 0 ]]
then
    echo "New error"
fi
# sh suppressWarn.sh
WARNING: initlog is deprecated and will be removed in a future release
v1 v2 v3
New error
