totem tag configures behavior of totem and interfaces.
cypto_cipher and crypto_hash:
Used for mutual node authentication. If you choose to
enable this, then do remember to create a shared
secret with "corosync-keygen".

<totem version="2" crypto_cipher="none" crypto_hash="none">
<!--
interface tag to define at least one interface to communicate
over. If you define more than one interface stanza, you must
also set rrp_mode.
Main parameters:
ringnumber:
Rings must be consecutively numbered, starting at 0.
bindnetaddr:
This is normally the *network* address of the
interface to bind to. This ensures that you can use
identical instances of this configuration file
across all your cluster nodes, without having to
modify this option.
However, if you have multiple physical network
interfaces configured for the same subnet, then the
network address alone is not sufficient to identify
the interface Corosync should bind to. In that case,
configure the *host* address of the interface
instead: bindnetaddr="192.168.1.1"
mcastaddr:
When selecting a multicast address, consider RFC
2365 (which, among other things, specifies that
239.255.x.x addresses are left to the discretion of
the network administrator). Do not reuse multicast
addresses across multiple Corosync clusters sharing
the same network.
mcastport:
Corosync uses the port you specify here for UDP
messaging, and also the immediately preceding
port. Thus if you set this to 5405, Corosync send
messages over UDP ports 5405 and 5404.
ttl:
Time-to-live for cluster communication packets. The
number of hops (routers) that this ring will allow
itself to pass. Note that multicast routing must be
specifically enabled on most network routers.

<!--
Logging tag for defining various logging options
Main parameters:
fileline:
Log the source file and line where messages are being
generated. When in doubt, leave off. Potentially useful for
debugging.
to_stderr:
Log to standard error. When in doubt, set to no. Useful when
running in the foreground (when invoking "corosync -f")
to_logfile:
logfile:
Log to a log file. When set to "no", the "logfile" option
must not be set.
to_syslog:
Log to the system log daemon. When in doubt, set to yes.
debug:
Log debug messages (very verbose). When in doubt, leave off.
timestamp:
Log messages with time stamps. When in doubt, set to on
(unless you are only logging to syslog, where double
timestamps can be annoying).

Logger susys tag is used to overwrite default settings for given
subsys if needed.
-->
<logger_subsys subsys="QUORUM" debug="off" />
