Hi Roque
Sorry for delay response and thanks for continou feedback to solve a problem
I followed your indication but i don't found a solution or one key to solve a problem.
I checked my packages, I verified python section about IOS apply template and controlled my template but i don't know if.... "there is light at the end of the tunnel" :-(
So,
I created a Case report pdf file to aggregate all steps on this test
- Clear all services
- Start config with MTU 9202
- Config service
- Commit dryrun with debug template
- commit
- Verify RefCount ( Not change, RefCount remain on value "2")
- Rollback
For all detail, please see the attached pdf file.
At the same time, I showed the IOS-XR configuration about same services, and I found RefCount ugual 1
nso@ncs# show running-config devices device OPM-9K1-F2 config cisco-ios-xr:interface TenGigE 0/6/0/4.251 | display service-meta-data
devices device OPM-9K1-F2
config
! Refcount: 1
! Backpointer: [ /ncs:services/movePWService:movePWService[movePWService:name='mau3'] ]

encapsulation dot1q 2 second-dot1q 251
no shutdown
! Refcount: 1
rewrite ingress tag pop 2 symmetric
exit
!
Test Nr 2 - Modify backup xconnect configuration
To clear all doubts about IOS template, I created a second template to modify backup xconnect configuation
IOS CLI Configuration
interface GigabitEthernet9/1
description porta per TEST NSO Valerio
mtu 9216
service instance 250 ethernet
encapsulation dot1q 250
rewrite ingress tag pop 1 symmetric

mtu 9202
IOS BK XML Template
---- Part of XML BACKUP IOS TEMPLATE ----
<interface xmlns="urn:ios">
<GigabitEthernet when="{$remotePortType = 'GigabitEthernet'}">

<vcid>{$pwIdNew}</vcid>
</peer>
</backup>
<mtu>9202</mtu>
</xconnect>
</instance>
</service>
</GigabitEthernet>
I execute the same services, but this time I don't have any problem, BackUp are correctly modified and MTU are not erased
I verified also the service-meta-data and also in this case, I have a RefCount egual to "2"
devices device A1-MDR

Test Nr 3 - Clear all service instance and recreate with same number configuration
I tried also with delete the service instance on xml template and create but the problem remain the same.

Last Test - New packages IOS
I created a new packages, without python logic and only with 1 template xml. This packages remove only shutdown configuration on a GIgabitEthernet interface.
The goal of this are to verify RefCount value
<config-template xmlns="http://tail-f.com/ns/config/1.0"
servicepoint="port-turn-up">
<devices xmlns="http://tail-f.com/ns/ncs">
<device>
<name>{/device}</name>
<config>
<interface xmlns="urn:ios">
<GigabitEthernet>
<name>{/interface_id}</name>
<shutdown tags="delete"></shutdown>
</GigabitEthernet>
</interface>
</config>
</device>
</devices>
</config-template>When I lanch the services, debug template are simply this
nso@ncs(config-port-turn-up-TestRFCOUNT)# commit dry-run | debug template
Evaluating "/device" (from file "port-turn-up-template.xml", line 10)

}
}
}
}
services {
+ port-turn-up TestRFCOUNT {
+ device A1-MDR;
+ interface_type GigabitEthernet;
+ interface_id 9/5;
+ }
}
}
}After commit, the RefCount on this interface are..
nso@ncs# show running-config devices device A1-MDR config ios:interface GigabitEthernet 9/5 | display service-meta-data
devices device A1-MDR
config
! Refcount: 2
! Backpointer: [ /ncs:services/port-turn-up:port-turn-up[port-turn-up:name='TestRFCOUNT'] ]
ios:interface GigabitEthernet9/5
no switchport
no ip address
no shutdown
exit
!
!
nso@ncs#
Maybe I will make a mistake, but it would seem that ned IOS always sets RefCount to 2
I hope all tests are clear
Regards
Maurizio
