SMCR - Command Syntax



One or more SMC-R devices.


Generic SMC information.


Linkgroup(s) or link(s) used by SMC-R.


SMC-R statistics.

The names of all objects can be abbreviated down to a unique stem. For example device can be abbreviated to dev or just d. Man pages in See Also section contain more  information for individual objects.


Specifies the action to perform on the object. The set of possible actions depends on the object type. As a general rule, it is possible to show or link-show objects, but some objects do not allow all of these operations. The help command is available for all objects. It prints out a list of available commands and argument syntax conventions.

If no command is given, a default command  is assumed.

Return Codes

Successful smcr command returns 0 and displays the requested linkgroup, link or device information. If an error occurs, smcr writes a message to stderr and completes with a return code other than 0. Possible  error messages to stderr in case of non-zero return code:

SMC module not loaded

Either kernel is not supporting the smcr tool or the smc kernel module is not loaded.
