1. Has anybody played around with flex links and vlan-move?

According to the documentation you have to configure a VLAN ID which is the
lowest VLAN ID on the interface ???.

" Configure a physical Layer 2 interface (or port channel), as part of a Flex
Link pair with the interface. The MAC address-table move update VLAN is the
lowest VLAN ID on the interface. [...] Configure a physical Layer 2 interface
(or port channel) and specify the VLAN ID on the interface, which is used for
sending the MAC address-table move update. "

k.htm

2. The example is absolutely confusing but reading through the line what I can
see is that I need to do the following:

a. Enable redundancy:
switchport backup interface interface-id

b. Configure preemption (optional)

switchport backup interface interface-id preemption mode [forced | bandwidth |
off]

c. configure mac table move

switchport backup interface interface-id mmu primary vlan vlan-id (??)

mac address-table move update transmit

Any help or suggestion welcome
