[rancid] Nexus 1000v switch-router

[Charles T. Brooks]

OK, I'm not sure what's going on, so bear with me....  I made these changes to rancid 3.4.1 on RHEL 7:

[root at git ~]# diff /usr/share/perl5/vendor_perl/rancid/nxos.pm /usr/share/perl5/vendor_perl/rancid/nxos.pm.2016-06-29

103c103
<     $DO_SHOW_VLAN = 1;
---
>     $DO_SHOW_VLAN = 0;
339c339
<       return(-1) if (/\% Invalid command at /); # CTB for Heasley
---
>       return(1) if (/\% Invalid command at /);
663,664c663,664
<       if (!/^VTP Operating Mode\s+:\s+(Transparent|Server)/) {
<           $DO_SHOW_VLAN = 0;
---
>       if (/^VTP Operating Mode\s+:\s+(Transparent|Server)/) {
>           $DO_SHOW_VLAN = 1;

I then changed the device-type for the Cisco 1000v from "cisco" to "cisco-nx" and let it run the usual hourly scheduled stuff.

Rancid correctly reported the change of device type via email, and /var/log/maillog is all copacetic.  However, it does not show any changes in the archive other than the line in router.db, nor have I been mailed any diffs.

 I will let it run over the weekend and report back Tuesday.

> Hmmmm... I'll answer the second question first.  No, neither the nexus 5K nor the 1000v has "show vtp status".  It's possible that we don't have a feature licensed/loaded that would enable this, I don't really know.  The NX-OS version on the 5K I looked at is not the very  latest greatest but it's not terribly old, either.

Does this restore the show vlan output?
