CSM 4.1 - Flexconfig (Syntax errors detected - Failed to setup Velocity Engine to validate syntax)

noc — Fri, 21 Feb 2020 12:18:42 GMT

Hi,

I am trying to build a simple flexconfig to remove some aaa statements. When I try to create any

basic flexconfig, I get the following error msg:

Syntax errors detected

Failed to setup Velocity Engine to validate syntax

Please correct errors.

The flexconfig consisted of the following cmd:

no aaa group server tacacs+ server123

I also tried cloning an existing example "IOS_enable_SSL", rename and recieved the same error.

What is the Velocity Engine and how can I verify that this component is working correctly?

Regards

Kevin

Try downgrading Java version on your machine.

This version works: java version "1.6.0_03"

Hi,

I've got the same issue with CSM 4.2 SP1 while trying to add sysopt connection tcpmss 0.

Using latest java on my local machine (for security reasons no downgrade possible).

Any solution?

This had worked in 3.3.x.

Just updated my local Java installation to Java 7 Update 4 (the current one) and Flexconfigs work again

Can someone provide valid java version for CSM 4.3 SP1? I'm using newest Java 7 update 11 and FlexConfigs don't work at all. New or existing configs, no difference. Same error

With Java 7 Update 7+ (or so) it also stopped working again.

I'm now using a VM with Win XP and Java 6 to configure my Flex Configs.

Just discovered that I once saved this bug here: https://www.cisco.com/cisco/psn/bssprt/bss?searchType=bugIdSearch&bugId=CSCtz91443

They write since around today that it's finally fixed. Maybe this actually also fixes our issue here. Sadly there isn't yet a version given in which it's fixed.

An Update. It still happens with CSM 4.4, but I discovered now that it works if I start CSM with "Run as admin".

I can verify that it still happens with CSM 4.4 SP1 but that running CSM using "run as administrator" works here too.
