VLAN status is up/down on 7600

Hello everybody,

I have an issue where an EVC service instance is configured on one physical interface, however, VLAN interface status is up/down, knowing that there are MAC entries for this VLAN know over this interface.

When adding the VLAN on any other interface, it comes up.

Other service instances are configured on same physical interface and they are up.

Is there any well-known bug or problem might be causing this to happen?


interface GigabitEthernet7/0/18

service instance 2573 ethernet

  encapsulation dot1q 2573

  rewrite ingress tag pop 1 symmetric

  bridge-domain 2573

#show int vlan 2573

Vlan2573 is down, line protocol is down

#show mac-address-table dynamic vlan 2573

Legend: * - primary entry

        age - seconds since last seen

        n/a - not available

  vlan   mac address     type    learn     age              ports

I have seen the same problem with another site with same symptoms.

I have cleared the service instance for the VLAN under the interface, and the problem is resolved.

Is this a well-know issue/bug?

Hi Amr,

which IOS is your 7600 running?

Which module do youhave in slot 7?

Did a SSO switchover between 2 supervisors (if present) occurred before you noticed the issue?
