configuration hierarchy with the top command and then use the show | compare command,
which is equivalent to the show | compare rollback 0 command. This is actually
two commands: the show command displays the entire configuration, and the
output is piped to the compare command, which lists only the differences between the
two commands (just like the Unix diff command).
The output shown in the “Solution” indicates that you have deleted the fe-1/0/1
interface from the [edit interfaces] configuration hierarchy. The first line of the
output shows the hierarchy level, and the minus signs indicate the deletions. Plus
signs are used when you have added statements, as in this example:
[edit]
aviva@RouterG# show | compare
[edit interfaces lo0 unit 0 family inet]
address 192.168.19.1/32 { ... }
+ address 127.0.0.1/32;
You can also compare the current configuration with a previously committed one.
The second command shows how to do this. rollback 1 is the version of the configuration
you committed immediately before committing the current one. The output
shown above indicates that the export send-direct statement was present at the
[edit protocols ospf] hierarchy in the previous configuration but has been removed.
You can also use a filename with the compare command to compare the candidate
configuration to a saved file. This supports URLs and scp-style filenames, so you can
use commands such as the following:
[edit]
aviva@RouterG# show | compare aviva@archives:nightly/my-rtr/2005-12-01.conf
[edit system login user testuser]
- class operator;
+ class read-only;
