I have 2 switches with a trunk between them (both ports set to <sw mode trunk>, <sw nonnegotiate>). One is a 3650 and the other is a 2960.
The 3650 is in VTP server mode
The 2960 is in VTP client mode (both ver 1)
Pruning is enabled on both switches
The 2960 switch has only 2 vlans enabled in it of a network total of 15. Here I am showing the ports that are in vlans on the 2960:
VLAN Name Status Ports

Here I am showing the output from the interface trunk on the 3650:
Port Mode Encapsulation Status Native vlan
Te1/0/40 on 802.1q trunking 1
Port Vlans allowed on trunk
Te1/0/40 1-4094
Port Vlans allowed and active in management domain
Te1/0/40 1,4-5,11-13,328-329,688
Port Vlans in spanning tree forwarding state and not pruned
Te1/0/40 1,4-5,11-13,328-329,688
Im perplexed as to why pruning is not working

To fix this, I turned off VTP pruning globally and then re-enabled.
