 config
 files                 List saved configuration files.
 hash                  Display the hash calculated for the startup
                       configuration.
 interface             Show the startup configuration for interfaces.
 oobm                  Show the startup configuration for OOBM.
 

To display the hash calculated for the startup configuration:

switch(config)# show config hash
The hash must be calculated.  This may take several minutes.

Continue (y/n)? y

Startup Configuration hash:

4f66 8b77 6b66 e5fb 0c12 f7fb 8ea6 b548 af2e 2e03

This hash is only valid for comparison to a baseline hash if
the configuration has not been explicitly changed (such as
with a CLI command) or implicitly changed (such as by the
removal of a hardware module).

switch(config)# show config hash
recalculate           Calculate hash (if needed) without prompting.

This hash is only valid for comparison to a baseline hash if
the configuration has not been explicitly changed (such as
with a CLI command) or implicitly changed (such as by the
removal of a hardware module).

To display the hash calculated for the running configuration:

switch(config)# show running-config hash
The hash must be calculated.  This may take several minutes.
