JINJA - monitor session configuration

[peter.lazok]

Hello,

is it possible to build jinja variable in DNA-C for erspan monitoring configuraiton?

name internal_erspan
monitor session 12 type erspan-source
source interface Gi1/0/6 - 7 , Gi1/0/13 , Gi1/0/20 , Gi1/0/27 , Gi1/0/29 , Gi1/0/31 , Gi1/0/34 , Gi1/0/36 , Gi1/0/39 - 48
destination
erspan-id 2
mtu 9000
ip address X.X.X.X
origin ip address X.X.X.Y

I have tried to do something like:

monitor session {{ session_id }} type erspan-source
source interface {{ test_interface }} both # where interface has been binded to source as portName with option to select multiple options
destination
erspan-id 2
mtu 9000
ip address X.X.X.X
origin ip address X.X.X.Y

but I got an output: 

source interface [GigabitEthernet1/0/13, GigabitEthernet1/0/12, GigabitEthernet1/0/17, GigabitEthernet1/0/9, GigabitEthernet1/0/15, GigabitEthernet1/0/2, GigabitEthernet1/0/10, GigabitEthernet1/0/3, GigabitEthernet1/0/4, GigabitEthernet1/0/14, GigabitEthernet1/0/8, GigabitEthernet1/0/11, GigabitEthernet1/0/16, GigabitEthernet1/0/5, GigabitEthernet1/0/7, GigabitEthernet1/0/6] both

As is visible from output above, there are characters "[" and "]" and it is not consumed by switch of course.

I tried to remove it using:

source interface {{ test_interface|replace('[','')|replace(']','') }} both

or 

source interface {{ test_interface|regex_replace('\[|\]','') }} both

or

source interface {{ test_interface.replace('[','').replace(']','').split(', ')|join(', ') }} both

or

source interface {{ test_interface.split(', ')|map('regex_replace', '\[|\]','')|join(', ') }} both

None from above worked, there is an issue with Syntax error.

Would someone provide piece of advice how to solve my problem, please?

Thank you,

Peter

Hello Peter,

Yes it's possible to apply erspan monitoring configuraiton using jinja.

You can do this by using network templates as you already did. After replicating your configuration, it seems that the issue comes from the "source interface" command. More specifically, try to run it again without using "-" for interface range. You can include all the desired interfaces by separating them with commas. 

After that, you provision the device and the configuration will be pushed.
