Cisco PVRSTP changing 1 vlan instance with multiple running

Hello,

Was wondering if anyone had ran into this. I have a configuration 4500 Cisco switches running per vlan rapid stp. I need to alter 1 VLANs spanning tree instance however we've hard coded all vlans 1-4094 to a fixed priority of 4096.

​

If I wanted to change just one VLANs spanning tree do I need to reinput all of the other VLANs (e.g. 1-238 priority 4096, 240-4094 priority 4096 and set the VLAN i want to the priority i need) or just setting the single VLAN as different priority be sufficient? I can't lab this unfortunately GNS3 IOU aren't behaving.

Thanks

​
