This object's DESCRIPTION is empty in the source MIB, so its meaning is inferred from its name, syntax, and table role: it reports the OMSCmdGroup classification that a given entry in the command-capabilities table belongs to, grouping related supported commands together. An admin would use it to filter or organize the capability table by functional command category rather than reading every entry individually. For illustration, entries sharing the same cmdGroup value might represent all the file-operation commands versus all the diagnostic commands the device supports.
