mismatch while entering a command to device vs device template

erdemk — Wed, 16 Sep 2020 12:56:40 GMT

Dear Community members,

I need some help.

While creating a Device Template, i cannot enter some CLI command into device template, although i can execute them on the Device ( either directly on device CLI or via NSO, it is same ).

I appreciate any guidance on the reason for this and guidance on how to run a Compliance report for those commands as i cannot enter them into the template.

nso ver : 5.3.0.1

ned : cisco-ios-cli-6.43

Definition of the issue :

CASE 1 : ntp server

i can execute command

ntp server 195.33.242.133

on the device, but not on the Device Template

CSE 2 : logging

i can execute command

logging 10.210.162.238

on the device, but not on the Device template..

Below are command execution output for like "logging ? " or "ntp server ? " and my notes and YANG portion for these commands out of IOS NED for both cases :

CASE 1 : ntp server

When i try to execute command on Device

admin@ncs(config-config)# ntp server ?
Possible completions:
<IP address> <--- there is IP address field here
<string, min: 1 chars, max: 253 chars>
<Hostname, A.B.C.D or X:X:X:X::X> Address of peer
ip Use IP for DNS resolution
ipv6 Use IPv6 for DNS resolution
vrf VPN Routing/Forwarding Information

When i try to execute command on Template :

admin@ncs(config-config)# ntp server ?
Possible completions:
ip ipv6 peer-list vrf <--- there is peer-list field here, in which there is IP address

IOS YANG for ntp server :

// ntp server *

container server {

tailf:info "Configure NTP server";

uses ntp-peer-grouping;

// ntp server ip *

container ip {

tailf:info "Use IP for DNS resolution";

}

CASE 2: logging

When i try to execute command on Device :

admin@ncs(config-config)# logging ?

Possible completions:

<string, min: 1 chars, max: 253 chars>

<Hostname or A.B.C.D> IP address of the logging host <------------- there is hostname for Template, see blow

alarm Configure syslog for alarms

buffered Set buffered logging parameters

cmts CMTS config commands

console Set console logging parameters

discriminator Create or modify a message discriminator

esm Set ESM filter restrictions

event Global interface events

exception Limit size of exception flush output

facility Facility parameter for syslog messages

history Configure syslog history table

host Set syslog server IP address and parameters

ip IP configuration

linecard specify logging parameters for a linecard messages

message-counter Configure log message to include certain counter value

monitor Set terminal line (monitor) logging parameters

origin-id Add origin ID to syslog messages

persistent Set persistent logging parameters

queue-limit Set logger message queue size

rate-limit Set messages per second limit

reload Set reload logging level

snmp-authfail

snmp-trap Set syslog level for sending snmp trap

source-interface Specify interface for source address in logging

transactions

trap Set syslog server logging level

When i try to execute command on Template :

admin@ncs(config-config)# logging ?

Possible completions:

alarm buffered cmts

console discriminator esm

event exception facility

history host hostname <------------- there is no as such hostname for Device CLI, see above

ip linecard message-counter

monitor origin-id persistent

queue-limit rate-limit rate-limit-conf

reload snmp-authfail snmp-trap

source-interface trap

IOS YANG for logging : ( is very long, hence i only included the hostname portion , which -i believe- for "logging <IP Address>"

container logging {

tailf:info "Modify message logging facilities";

// logging *

list hostname {

tailf:info "Hostname or A.B.C.D;;IP address of the logging host";

tailf:cli-drop-node-name;

tailf:cli-suppress-mode;

tailf:cli-delete-when-empty;

key host;

leaf host {

tailf:cli-disallow-value "esm|alarm|buffered|facility"+

tailf:cli-full-command;

type inet:host {

tailf:info "Hostname or A.B.C.D;;IP address of the logging host";

}

Hi,

The NTP commands in your template should look like:

<config>
       <ntp xmlns="http://tail-f.com/ned/cisco-ios-xr">
        <server>
          <server-list>
            <name>1.2.3.4</name>
          </server-list>
        </server>
        <source>
          <Loopback>0</Loopback>
        </source>
      </ntp> 
      </config>

Similarly, your logging configuration in the template should look like

<config>
        <logging xmlns="http://tail-f.com/ned/cisco-ios-xr">
          <trap>debugging</trap>
          <monitor>debugging</monitor>
          <buffered>
            <type>informational</type>
          </buffered>
          <host>
            <address>1.2.3.4</address>
            <vrf>default</vrf>
            <severity>info</severity>
            <port>default</port>
          </host>
        </logging> 
      </config>

One thing that helps figure these types of things out is to go to a device that has the configuration you want and issue command like:

show running-configuration | display xml

regards

Richard

Dear RichardD2,

very good. now, i am able to synchronize template and device cli. show run | display xml on device made the trick.

many thanks.
