Bridge Domain down on two interface in EVC mode

[M.Fly]

Hi all,
we have a Nexus 7004 and have activate the EVC feature.
We have configured a Port-Channel to ingress some traffic, this traffic have a rewrite function to add a vlan tag on top on other vlan tag like this:

interface port-channel22
service instance 91 ethernet
encapsulation default
rewrite ingress tag push dot1q 91 symmetric

interface Ethernet3/23
service instance 911 ethernet
encapsulation dot1q 91

bridge-domain 911

bridge-domain 911
member port-channel22 service-instance 91
member Ethernet3/23 service-instance 911

If we show the bridge domain status, de B-domain always stay down:

(config)# sh bridge-domain

Bridge-domain 911 (2 ports in all)
Name:: Bridge-Domain911
Administrative State: UP Operational State: DOWN
EFP-Eth3/23.911
EFP-Po22.91

We want to retag the ingress packet and viceversa remove a tag to egress, but the b-domain still in down state and no mac address in the brodcast domain is visible.
How can make up and running this scenario on Nexus 7000? We have some ASR920 with no problem with bridge-domain in down state.

  - Could you try to sync the po22 encapsulation with Ehernet3/23 as in :
          interface port-channel22
          service instance 91 ethernet
          encapsulation dot1q 91
          rewrite ingress tag push dot1q 91 symmetric

we try on monday, but the problem is that i have multiple VLAN to intercept with the service instance, if i use specific dot1q encapsulation i must to configure one service instance per VLAN, i have over 200 VLAN to reincapsulate in outer VLAN.
On the ASR920 there is a option to declare a VLAN range in the service instance, but on the Nexus 7004 i don't have this option.

You know the numeric limit of the service instance per interface?

We want to reincapsulate some VLAN on ingress interface to outer VLAN 91 and reincapsulare some other VLAN to outer 911 VLAN like this:
VLAN 50-2000 to outer VLAN 91
VLAN 2001-4000 to outer VLAN 911 (egress on another 10G interface)

Thanks a lot.
