Re: [Devmon] Initial Configuration

[<mv...@so...>]

Hi, 

I've uploaded tested templates with the cisco 857 and 871 devices. 

I have a minor issue with if_load/Di0 interface on the 857 and a 
consequential problem with the exceptions in that folder.  I am sure it is 
more related to my lack of experience with this rather than devmon, so I'll 
update it once I've worked it out. 

In the meantime, the other tests seem to work fine. 

the templates have been taken from the cisco-asa template, so no credit at 
all on my part. 

 

Thanks for the help at the start, overall devmon is working just as 
expected. 


Regards,
Mario
