Thanks Santiago. I couldn't get the full key spec filter to work, but understand there's a pending DDTS to make the partial key work so will wait until the fix is available. thanks Hung ... View more

Hi Einar, I don't have access to 6.3.1.22I. I use EVE-NG and it happens to have xrv-xtc image which is 6.3.1.12I so I can't try 6.3.1.22I. However, I just realise that 6.3.1 is a development image - I intend to use a stable image rather than a development one. I've tried loading IOX XRv 6.1.2 and there is no XML encoding issue. I'll use XRv 6.1.2 from now. Thanks for your help. regards Hung ... View more

Thanks Einar and Santiago for looking into this. The issue is on an IOS-XRv version 6.3.1.12I in my lab. I've tried pulling running-config from an IOS-XRv 9000 version 6.1.2 and I don't see the issue. Below is the output of the authentication config from IOS-XRv 9000 in my lab. <aaa xmlns=" http://tail-f.com/ns/aaa/1.1 ">    <authentication>     <users>      <user>       <name>hung</name>       <uid>9000</uid>       <gid>100</gid>       <password>$1$b1NO$7sg6B6P7ygIaXuEohrPnv0</password>       <ssh_keydir>/var/confd/homes/hung/.ssh</ssh_keydir>       <homedir>/var/confd/homes/hung</homedir>      </user> Hope it helps Cisco XR team further to localise the issue. thanks Hung ...

I've attached a verbose output of the ncc.py get-running issue. As it's a slight digress from the main topic, I can put this to a separate topic if need be, let me know. regards Hung ... View more

Thanks Einar and abhirame. I can't run ncc.py to retrieve running-config. It throws the error below. I've always had this issue with ncclient to retrieve full running-config, while retrieving a filtered running-config or retrieving capabilities is ok. Did you come across this before? lxml.etree.XMLSyntaxError: Input is not proper UTF-8, indicate encoding ! thanks Hung ... View more

Hi Einar, on a side note, is there a way to use ydk to ask for all targets that an ACL is applied on? Instead of modifying a living ACL, I can detach the ACL from all targets, remove the ACL, re-create the ACL with new content and apply the new ACL on all targets therefore it'd be useful to retrieve existing targets of an ACL from the device. thanks Hung ...

Thank you Einar, I can replicate in my lab everything you said. Thanks for your help. regards Hung ... View more

Thanks Shruti for quick reply, I can use that sample app to delete the whole ACL, but not just an ACL entry in an ACL. Have you got a sample app to delete an ACL entry without having to delete the whole ACL? Thanks Hung ... View more
