主题: a question about ietf-hardware yang module
Hi andy and all,
I’m implementing ietf-hardware.yang, and I have a question about
/hardware/last-change.
module: ietf-hardware
+--rw hardware
+--ro last-change? yang:date-and-time
+--rw component* [name]
+--rw name string
+--rw class identityref
+--ro physical-index? int32 {entity-mib}?
+--ro description? string
+--rw parent? -> ../../component/name
+--rw parent-rel-pos? int32
+--ro contains-child* -> ../../component/name
+--ro hardware-rev? string
+--ro firmware-rev? string
+--ro software-rev? string
+--ro serial-num? string
+--ro mfg-name? string
+--ro model-name? string
+--rw alias? string
+--rw asset-id? string
+--ro is-fru? boolean
+--ro mfg-date? yang:date-and-time
+--rw uri* inet:uri
+--ro uuid? yang:uuid
+--rw state {hardware-state}?
| +--ro state-last-changed? yang:date-and-time
| +--rw admin-state? admin-state
| +--ro oper-state? oper-state
| +--ro usage-state? usage-state
| +--ro alarm-state? alarm-state
| +--ro standby-state? standby-state
+--ro sensor-data {hardware-sensor}?
+--ro value? sensor-value
+--ro value-type? sensor-value-type
+--ro value-scale? sensor-value-scale
+--ro value-precision? sensor-value-precision
+--ro oper-status? sensor-status
+--ro units-display? string
+--ro value-timestamp? yang:date-and-time
+--ro value-update-rate? uint32
Last-change’s description: "The time the '/hardware/component' list changed in
the
operational state.";
It seems this description means any change (configuration change or state
change) of list /hardware/component/ will cause the update of
/hardware/last-change.
But in description of notification:hardware-state-change
notification hardware-state-change {
description
"A hardware-state-change notification is generated when the
value of /hardware/last-change changes in the operational
state.";
reference
"RFC 6933<https://tools.ietf.org/html/rfc6933>: Entity MIB (Version 4)
- entConfigChange";
}
This notification means if any change occurs in /hardware/last-change, a
notification will be reported.
This notification also refers to Entity MIB’s entConfigChange.
My question is whether only configuration change of hardware component will
cause the update of /hardware/last-change?
