CliTemplates/Apache Velocity Template Language - split function

carl.simpson2 — Mon, 12 Dec 2016 17:21:16 GMT

Hi,

Can anyone provide a sample Cisco Prime CliTemplate making use of split?

I'm looking to feed in a variable containing a /48 IPv6 prefix and then use parts of it in various sections of the device configuration.

So for example I'd like to take '2001:DB8::/48' split on say '::'

Giving me '2001:DB8' in a variable which I can append '::/64' to use on an interface.

I've tried the examples shown here but it breaks the template in Prime: apache - Using velocity split() to split a string into an array doesnt seem to work - Stack Overflow

Taken from the link about, should something like the below work (Giving me 'This')?

#set ($myString = “This|is|my|dummy|text”)

#set ($myArray = $myString.split("\|"))

$myArray[0]

Thanks,

Carl

Carl,

Based on what you're after, I think the CLI content that you're looking for is more like this

#set ( $ipv6_64subnet = $ipv6_string.split("::")[0].concat("::/64") )

do_work $ipv6_64subnet

I've put that in an XML payload that you can POST to v1/op/cliTemplateConfiguration/upload. It worked as expected on my 3.1.5 (dev build of the 3.1.5 patch) server when deployed via either the API or GUI.

<?xml version="1.0" ?>
<cliTemplate>
  <content>#set ( $ipv6_64subnet = $ipv6_string.split("::")[0].concat("::/64") )
do_work $ipv6_64subnet</content>

  <deviceType>Routers</deviceType>

  <variables>
<variable>
<description>IPv6 String</description>
<displayLabel>IPv6 String</displayLabel>
<name>ipv6_string</name>
<required>true</required>
<type>String</type>
</variable>
</variables>
</cliTemplate>
