[rancid] VLAN 1 port members change when port goes down

[Martin Barry]

Hi list

I'm trying to tune the signal to noise ratio from rancid and I have an issue
with VLAN 1 (Yes, yes, I know you shouldn't use it. Dealing with legacy
config here).

When a port in VLAN 1 goes down, the next time rancid runs I get diffs like:

!
!VLAN: VLAN Name Status Ports
!VLAN: ---- -------------------------------- --------- -------------------------------
- !VLAN: 1 default active Fa0/1, Fa0/2, Fa0/3, Fa0/6
- !VLAN: Fa0/7, Fa0/9, Fa0/11, Fa0/13
- !VLAN: Fa0/15, Fa0/19, Fa0/20, Fa0/21
- !VLAN: Fa0/22, Fa0/23, Fa0/26, Fa0/28
- !VLAN: Fa0/30, Fa0/32, Fa0/34, Fa0/36
- !VLAN: Fa0/39, Gi0/2
+ !VLAN: 1 default active Fa0/1, Fa0/2, Fa0/3, Fa0/5
+ !VLAN: Fa0/6, Fa0/7, Fa0/9, Fa0/11
+ !VLAN: Fa0/13, Fa0/15, Fa0/19, Fa0/20
+ !VLAN: Fa0/21, Fa0/22, Fa0/23, Fa0/26
+ !VLAN: Fa0/28, Fa0/30, Fa0/32, Fa0/34
+ !VLAN: Fa0/36, Fa0/39, Gi0/2
!VLAN: 27 VLAN0027 active Fa0/45, Fa0/46, Fa0/47, Fa0/48
!VLAN: 100 VLAN0100 active
!VLAN: 110 VLAN0110 active


When the port comes back up, I get the reverse.

Anyone figured out a way to stop the port memberships flapping or exclude it
from the rancid diffs?

cheers
Marty

I'm seeing this same thing in our diffs. Any word on a work around or
should I just ignore it?

IIRC, this occurs when VTP is enabled. it may occur in other instances
that i'm not aware of. either disable vtp or comment-out 'show vlan'
in the rancid script.
