State
This field is comprised of the current protection group state, the cause, and the cause
source.
Current protection group state:
• N—Normal state. The working and protection tunnels operate correctly, and
traffic travels along the working tunnel.
• UA—Unavailable state. The protection tunnel is unavailable.
• PA—Protecting administrative state. The externally configured switching action
enables traffic to travel along the protection tunnel.
• PF—Protecting failure state. The working tunnel fails, and traffic is switched to the
protection tunnel.
• WTR—Wait-to-Restore state. The device is waiting for the wait time to switch traffic
from the protection tunnel to the working tunnel after the working tunnel recovers.
• DNR—Do-not-Revert state. Traffic is not switched from the protection tunnel to the
working tunnel after the working tunnel recovers.
Cause for the current protection group state:
• LO—Lockout of protection.
• P—A failure on the protection tunnel is detected by a signaling protocol.
• W—A failure on the working tunnel is detected by a signaling protocol.
• F—Forced switch.
• M—Manual switch.
• HO—Hold off. The device is waiting for the holdoff time to switch traffic from the
working tunnel to the protection tunnel after the working tunnel fails.
Cause source:
• L—Local.
• R—Remote.
For example, UA:LO:L indicates that the protection group becomes unavailable
because lockout of protection is performed on the local device.
