As Herman stated "show configuration committed", performed at a specific node level will show the commands that were specifically entered at that node. If you want to see the configuration that exists at a specific node, which include the settings at the specific node, along with any configuration that has been inherited from node levels above, then the command is "show configuration effective". If you want to identify where the configuration was inherited from, then the command is "show configuration effective detail". This will show each configuration command, and to the right of it, you will see the node level where the command was set/inherited from. Below is a small clip from the command.
(MM1) [mynode] #show configuration effective detail
crypto-local pki PublicCert master-ssh-pub-cert master-ssh-pub-cert # inherited from [/]
master-l3redundancy # local [/mm/mynode]
l3-peer-ip-address 192.168.240.100 ipsec ****** # local [/mm/mynode]
l3-sync-state Primary # local [/mm/mynode]
l3-sync-time 2 # local [/mm/mynode]
I hope this helps,
