corosync totem configuration values do not work in cluster.conf

Issue

• I am using the High Availability Add-On for Red Hat Enterprise Linux 6. After adding a totem interface via ccs (to try bind the cluster communication to a specific interface),

ccs -h node01 --exp interface totem ringnumber="0" bindnetaddr="172.16.154.0" mcastaddr="239.192.1.4"

my /etc/cluster/cluster.conf file now contains the section:

<totem>
    <interface bindnetaddr="172.16.154.0" mcastaddr="239.192.1.4" ringnumber="0"/>
</totem>

but corosync doesn't start with this configuration:

# service cman start Starting cluster:
   Checking if cluster has been disabled at boot...        [  OK  ]
   Checking Network Manager...                             [  OK  ]
   Global setup...                                         [  OK  ]
   Loading kernel modules...                               [  OK  ]
   Mounting configfs...                                    [  OK  ]
   Starting cman...                                        [FAILED]

Corosync logs show
