Wrap Status
Note
Any MAC address with the first four digits beginning with 11 (11xx.xxxx.xxxx) is a malformed address
and is denied; for example, 1100.2222.3333.

When changing ML1000 GE port states in a scenario with 802.17 RPR redundant interconnect
protection configured, the primary ML card remains active if at least one GE port is up.
protection configured, the primary ML card remains active if at least one GE port is up.
Conversely, if all GE ports are down, the redundant interconnect protection is triggered and the IEEE 0
interface shuts down on the primary card. When the IEEE 0 interface shuts down, the L2 topology state
changes to Steering.

Wrap Status
When a PoS port in a Cisco RPR L2 topology shuts down, CTM raises an alarm to indicate that the L2
topology has entered the corresponding protection state, which is referred to as the wrap state. The status
of the Layer 2 topology changes from the original state (Complete or Incomplete) to Complete-Wrapped
or Incomplete-Wrapped (see
