I have been reading the NETCONF standard and think you people have done=
a=20
great job! As I was reading, I thought of a question for which I haven=
't=20
found an answer. (I did find some posts that mentioned 'operational'=20=
commands when talking about what the WG should work on next---notificat=
ions,=20
or whatever---I hope my question doesn't just re-kindle an unrelated=20=
discussion topic and my question is left un-answered!) Please help me=20=
understand how this use case should work:
There are commands in network devices, like "sdm prefer routing" on a C=
isco=20
3750, that require a reload. However, I didn't see any built-in operat=
ion=20
for rebooting a device. How should this interaction with a device, whe=
n the=20
configuration option requires a reboot, work using NETCONF=3F
I thought of a few options:
0. NETCONF does only configuration--operational commands like "reload" =
are=20
outside the scope.
1. Ooops, we forgot about reload (not likely!) or just haven't got to i=
t=20
yet.
2. It's left to the data model--devices can expose a configuration elem=
ent=20
that results in a reload. Something like:
<rpc message-id=3D"101" xmlns=3D"urn:ietf:params:xml:ns:netconf:base:1.=
0">
<edit-config>
<target>
<running/>
</target>
<config>
<cli xmlns=3D=94http://example.com/schema/1.0/config/=94>
reload
</cli>
</config>
</edit-config>
</rpc>
The device would respond with a reply of <ok/>, close the NETCONF=20
connection, and then reload. (After typing this in, it seems really ho=
key.)
3. A device manufacturer can add a capability that adds a new operation=
. =20
Something like this:
<hello xmlns=3D"urn:ietf:params:xml:ns:netconf:base:1.0">
<capabilities>
<capability>
urn:ietf:params:netconf:base:1.0
</capability>
<capability>
http:/example.com/schema/1.0/reload
</capability>
</capabilities>
<session-id>4</session-id>
</hello>
And then you could send the device a NETCONF rpc with this new "reload"=
=20
operation when required. The rpc would look like this:
<rpc message-id=3D"102" xmlns=3D"urn:ietf:params:xml:ns:netconf:base:1.=
0">
<reload/>
</rpc>
The device would respond with a reply of <ok/>, close the NETCONF=20
connection, and then reload. (If NETCONF doesn't include a native "rel=
oad"=20
operation, then this makes the most sense---to me anyway!)
4. <your idea here...>
How should it work=3F
Thanks!
