Displaying current definition of zones

Do display the current defined zones on an EMC DS-300 fibrechannel switch the command "zoneshow" can be used on the commandline.
A sample output looks like the following:  

fcsw21:admin> zoneshow
Defined configuration:
 cfg:   configname0
                vmware0
 cfg:   configname1
                vmware0; vmware1
 zone:  vmware0
                cx4a; esx210; esx220
 zone:  vmware1
                cx4b; esx210; esx220
 alias: cx4a    50:06:01:62:3c:e0:87:5b
 alias: cx4b    50:06:01:6b:3c:e0:87:5b
 alias: esx210  10:00:00:00:c9:99:88:77
 alias: esx220  10:00:00:00:c9:99:88:87

Effective configuration:
 cfg:   configname1
 zone:  vmware0
                50:06:01:62:3c:e0:87:5b
                10:00:00:00:c9:99:88:77
                10:00:00:00:c9:99:88:87
 zone:  vmware1
                50:06:01:6b:3c:e0:87:5b
                10:00:00:00:c9:99:88:77
                10:00:00:00:c9:99:88:87

  The listing has been extremely shortened because of clarity.
Output shows the both defined configurations "configname0" and "configname1", the available zoning definitions and the defined aliases.
Starting with "Effective configuration" the current working configuration is show. Currently the configuration named "configname1", containing the two zones "vmware0" and "vmware1", is active. Both of them contains three "hosts" represented by their WWN.
