# NACM protocol operation rules
|
|
# @see RFC 8341 A.1 and A.3 (and permit-all from A.2)
|
|
# Tests for three protocol operation rules (all apply to module ietf-netconf)
|
|
# deny-kill-session: This rule prevents the "limited" group or the
|
|
# "guest" group from invoking the NETCONF <kill-session> protocol
|
|
# operation.
|
|
# deny-delete-config: This rule prevents the "limited" group or the
|
|
# "guest" group from invoking the NETCONF <delete-config> protocol
|
|
# operation.
|
|
# permit-edit-config: This rule allows the "limited" group to invoke
|
|
# the NETCONF <edit-config> protocol operation. This rule will have
|
|
# no real effect unless the "exec-default" leaf is set to "deny".
|
|
#
|
|
# From RFC8040, I conclude that commit/discard should be done automatically
|
|
# BY THE SYSTEM
|
|
# Otherwise, if the device supports :candidate, all edits to
|
|
# configuration nodes in {+restconf}/data are performed in the
|
|
# candidate configuration datastore. The candidate MUST be
|
|
# automatically committed to running immediately after each successful
|
|
# edit.
|
|
# Which means that restconf -X DELETE /data translates to edit-config + commit
|
|
# which is allowed.
|
|
|
|
# Magic line must be first in script (see README.md)
