Couldn't agree more. There is deep decoupling in IOS and IOS-XR
between CLI, SNMP and Netconf, so you can't know without research if
particular data is available via particular method. Most comprehensive
is screen-scraping.

Alcatel TimOS has inherent coupling between CLI and SNMP, if something
is possible to get or set in CLI, it's possible to get or set in SNMP.
Juniper JunOS has inherent coupling between CLI and XML presentation.
I absolutely love doing in scripts SSH exec channel for 'cli-command |
display xml' and get something parseable out, without resorting to
fragile screen-scraping.

Insha'allah IOS-XR 9.0 will have tight coupling of YANG and CLI,
although whole world has already moved to machine learning and our
manager is perl7 script.
