The E1SCC board sets NE IDs by using the DIP switch. S4 and S3 indicate DIP switches for setting NE IDs of the system control board. When the DIP switch is set to ON, the bit is 1. When the DIP switch is set to OFF, the bit is 0. The bit on the left is the most significant bit. Every time the DIP switch is set, reset the system control board for the new setting to take effect. For the E2SCC board, the NE ID can be set using the software.
Question:
If alarms are generated, NEs of earlier versions report the alarms to the NMS only for three consecutive times regardless of whether the NMS receives the alarms or not. In the latest version, NEs establish an alarm acknowledgment mechanism with the NMS. Therefore, when alarms are generated, the NEs continuously report the alarms to the NMS until they receive acknowledgment information from the NMS. For 4.0 and 5.0 platforms, which NEs on 320G and 1600G devices support the alarm acknowledgement mechanism?
Answer:
On the 4.0 platform, NEs support the alarm acknowledgement mechanisms since 4.08.04.20P03. On the 5.0 platform, NEs support the alarm acknowledgement mechanisms since 5.08.03.10.
