Through the returned k bytes, analyze the event:
1 8091 K_RECEIVED 0x0008 2007-6-28 12:3:52 0x01fd7f3a
1 8092 K_DIR 0x0000 2007-6-28 12:3:52 0x01fd8008
The K byte received in the M1000V3 NE standby path is 0x0008. It indicates that the protection mode of the opposite linear MSP is 1:N. In the M1000V3, the configured linear MSP is 1+1. Hence, it reports the K2_M alarm.
For the linear MS, the bit5 of K2 byte is 1. It indicates the 1:N linear MSP.
