Causes for not performing the active/standby switching when the E6LWF and E2LWF boards are configured with 1+1 protection in different subracks

18

Question:
Why does the active/standby switching cannot be performed when the E6LWF and E2LWF boards are configured with 1+1 protection in different subracks?
Analysis:
This problem occurs because the protocols on E6LWF and E2LWF are not compatible. When the protection group is configured and E6LWF is interconnected to E2LWF, due to incompatible protocols, the E6LWF misjudgment occurs which is caused by protocol data insertion on the E2LWF and an SF alarm is generated.
Root cause:
None
Answer:
Workaround: Do not interconnect E6LWF and E2LWF, so as to avoid problems caused by incompatible protocols.
Solution: Upgrade the board software to the 614 version, which can be obtained from V100R006C06B63 (5.08.06.62) and V100R005C04B049 (5.08.05.44).
Suggestion and Summary:
None
