I have a 5412R connected to a 6200F in production and they're working great.  I need to extend one of the vlans that exists on the 6200 through the 5412 but that would cause a vlan id collision so I'm doing vlan translation to change the vlan id as it leaves the 6200.  The issue is that spanning tree shuts the vlan down on that link as soon as I configure it.  The vlan in question is only tagged on a single port on the 5412 (the port that goes to the 6200) so I know there isn't a loop.  How to I prevent spanning tree from shutting it down?  Here's the relevant config for the 6200

CX-RFH(config-if)# show run cur
interface 1/1/50
    no shutdown
    no routing
    vlan trunk native 1
    vlan trunk allowed 44,102,4016
    vlan translate 1044 44
    exit
CX-RFH(config-if)# show run spanning-tree
spanning-tree mode rpvst
spanning-tree
spanning-tree vlan 44,102

And here's the relevant config from the 5412

vlan 1044
   name "rf2fields"
   tagged K3
   no ip address
   exit
spanning-tree
spanning-tree mode rapid-pvst
spanning-tree vlan 1044 

When everything is setup here's the spanning tree status from the 6200

CX-RFH(config)# show spanning-tree vlan 44

How do I get those ports to stop blocking?

Hi, if I read this sentence correctly: "A port with a VLAN translation configuration allows traffic only for the translated VLAN and the native VLAN; if it is
a member of more VLANS, it does not allow traffic for them." (see here at page 60) I understand that the 1/1/50 interface on the Aruba CX 6200F used as the uplink to the Aruba 5412R zl2 should be instead configured like:

interface 1/1/50
no shutdown
no routing
vlan trunk native 1
vlan trunk allowed 44
vlan translate 1044 44
exit

But, apart from the above detail, I'm pretty sure that your particular usage of RPVST between these two switches should be better addressed/explained.

Oh, wow!  That would be bad if it shut down all of my other vlans on that interface.  Fortunately it didn't.  I tried doing the same thing but using the native/untagged vlan instead of translation but RPVST still shut it down.  It's the strangest thing.  I have a spare pair of fibers so I can just light that up for this vlan but it seems weird that I have to do that just to get this working
