I only see one port configured and i see you statically configured the
Standby MAC-Address. I see a problem with this type of config: you can
not assign the same MAC to two different ports. Please try with two
routers and then play with the HSRP priorities to see what happens. I
just want to be sure that without "standby use-bia" or "standby
mac-address" configured on the routers, this will never work.

  Hello group,

  I still have doubts on this one. Why do i get Port-Security
  Violations as
  soon as i change the Active Router ? I know that "standby use-bia" or
  "standby mac-address" is an workaround to this problem but i saw this
  configuration in one of the major vendors CoD and it was working. If
  i
  remember well, the instructor had to change the maximum mac-addresses
  value
  from 2 to 3. Does it make any sense ? See bellow my configs and
  outputs.
  Both R2 and R5 are connected to SW2 which is a 3750 running
  12.2.25SEE.

  Thanks,
  Antonio
