[rancid] Cisco 3650 IOS-XE active VLAN port state changes

[on at LEFerguson.com]

Yeah, this is something I keep meaning to change as well.  I haven't done it, but I think you can just put something like 

next if (^!VLAN:); 

in showVLAN in ios.pm.   You'll see similar checks.  But I also just want to put a plug in that this is a good candidate for a rancid option.  I would think that people fall into two camps -- those who declare VLAN's by interface (and so are not likely to want to see the changes as interfaces change) and those who do not (who might). 

Just a thought...

Hello,

We are seeing an issue on several WS-C3650-48PS (IOS-XE) switches whereby almost every rancid check shows changes that are solely the port showing active or inactive on a particular vlan. Is there some way to ignore that? This appears to happen when a port state changes. An example of what we see each time is below.
