4500X with Trunked interfaces, VLAN's 11 and 14, but VLAN 1 is shown too
Looking to see if anyone else has run into this issue.
I am looking at an issue on a 4500X where VLAN 1 is seen yet not configured for the interfaces I am using. Also, when looking at the upstream switch, 6509, it shows a similar set-up with the interface connected to Te2/1/14 shows vlan 1 in the vlan database too, even though it is configured as a trunk and clearly seen as such.

I moved from Te2/1/14 to Te2/1/13, applied the same configuration and the issue is resolved. For some reason it seems like just that interface holds on to VLAN 1.
I had changed to an access interface and moved to VLAN 14
switchport access vlan 14
verified the VLAN database and it now showed the interface in VLAN 14. I removed it and placed the interface in the trunk and allowed the two VLAN's again, 11 and 14, checkec the VLAN database and it once again showed VLAN 1.
I even attempted to prune VLAN 1 and it had no impact.
