-o	The operation to perform. The only valid value is s for a set operation.
-a	The configuration data to set. The configuration data consists of attribute name/value pairs, which are in comma separated value (CSV) format. The configuration data must be enclosed in double quotes. The format of the configuration data is as follows: attribute-name=value,attribute-name=value,... Note that certain attributes accept a comma separated list of values, as follows: attribute-name=value,value,... ,... When a list of values is specified, the attribute name/value pair must be enclosed in double quotes. Depending on the shell being used, nested double quote characters may need to be preceded by an escape character, which is usually a ’#146; character. Valid attribute names: lpar_rmc_comm_ifs Comma separated list of management console network interfaces, in priority order, to enable for partition communication. The following special values are also allowed: all - enable all management console network interfaces for partition communication (default value) none - disable all management console network interfaces for partition communication rmc_comm_mode RMC communication mode Valid values: legacy - use TCP/UDP over port 657 only tls_preferred - use TLS over port 12601 if supported by the partition, otherwise use TCP/UDP over port 657 tls_exclusive - use TLS over port 12601 only rmc_conn_priority RMC connection priority Valid values: default - default priority direct - use direct TLS connections first. If connection is unsuccessful it will be proxied. indirect - use indirect or proxy TLS connections first
-r	Specify this option to restart the management console to apply the changes.
--help	Display the help text for this command and exit.

Enable only the eth0 interface for partition communication and restart the HMC to apply the change:

chpsm -o s -a "lpar_rmc_comm_ifs=eth0" -r

Enable the eth0 and eth1 interfaces for partition communication, giving priority to eth0:

chpsm -o s -a ""lpar_rmc_comm_ifs=eth0,eth1""

Set the RMC communication mode to tls_preferred and set the RMC connection priority to direct:

chpsm -o s -a "rmc_comm_mode=tls_preferred,rmc_conn_priority=direct"
