etherstub - backup interface?

Hi,

is it possible to tell etherstub, that one link is the backup for
another?

What I have in mind is simplifying/uniform zone setup/connectivity ->
zone management:

  CampusA ||       || CampusB
      +------------------+       2x10G       +--------------------+
      | Cisco 6509/3560X |<=================>|   Cisco Nexus 5010 |
      +------------------+                   +--------------------+
Uplinks:     ^ ^                                 ^ ^

/             T                                   T                    /

 \            v                                   v                     \

  etherstub is really a stub and you can not create it
  with any datalinks. So, the above is not possible.

  One option here is to create vnic1 on top
  of aggr0 and vnic2 on top of aggr1 and assign both of them
  to Zone A. You can then use IPMP on top of the VNICs
  in Zone A. You can repeat this for all the zones by
  creating more VNICs on top of aggr0 and aggr1.
