Event driven telemetry on Cisco IOS XR (IOSXRV9000)

[divyanshukumarpcm]

Hi,

I have a device XR 7.0.1 (IOSXRV9000). I wanted to set up event driven (on-change) telemetry (cadence is working fine).
But while creating subscription, I am getting this error:

It seems like it does not identify the command "include select-leaves-on-events"
Destination group and sensor group I have created similar to the cadence based telemetry:
telemetry model-driven
sensor-group entitymib
sensor-path Cisco-IOS-XR-sysadmin-entity-mib:ENTITY-MIB
commit

telemetry model-driven
destination-group divykkum2
address family ipv4 <ip> port 57565
encoding self-describing-gpb
protocol tcp
commit

How do I create Event driven subscription ?

Could be wrong here, i recall this feature was introduced in IOS XR 7.3.1. So you have to get a new version or use standard sensor-path configuration without the events option.

Hi,

Could you please verify with '?' whether this config is supported on the XR version you're using? (I suspect this feature was introduced in the later versions of XR. )
Also, note that event-driven telemetry is only supported for a limited set of sensor paths, and 'Cisco-IOS-XR-sysadmin-entity-mib.yang' is not supported.

Hope this helps!

Hi @bigevilbeard @rahusha7 thank you
I found out from documentation that "include select-leaves-on-events"  is indeed not supported for 7.0.x XR. However we can subscribe event driven telemetry by setting sample interval = 0
Rest all things are same.
But there are other issues, I am not receiving any notification on changing config.
