How to Configure the Uplink Redundancy Backup-Part 1
The Huawei MA5600 provides powerful redundancy backup mechanism. Redundancy or backup implements the high reliability and self-healing capability of the system, which maximally preserves the services provided by carriers and minimizes the loss in case of an accident.
Background Information Uplink Redundancy backup includes the following information:
Uplink aggregation group: Aggregate multiple Ethernet ports as an aggregation group to expand the bandwidth and balance the input and output load among member ports. In addition, the ports in an aggregation group back up each other, which enhances the link security.
NOTE:
The ETH and SCU boards support the configuration of the aggregation group.
Inter-board aggregation is supported between two SCU boards. The ETH board, however, does not support inter-board aggregation.
Link Aggregation Control Protocol (LACP) detection mode: In this mode, the Huawei MA5600 detects port faults and triggers the switch over through the LACP protocol.
Upstream port protection group: An upstream port protection group contains a working port and a protection port. In the normal state, the working port carries services. When the link of the working port fails, the system automatically switches the service on the working port to the protection port to ensure normal service transmission, thus protecting the uplink.
NOTE:A protection group works in either of the following modes:
Port status detection mode
Delay detection mode
Enhanced delay detection mode
Two ports of the protection group or the transmit ports on two boards are enabled. You can determine whether to perform a switchover according to the port status.
When the number of ports that are in the up state on the standby board is greater than the number of ports that are in the up state on the active board, a switchover is triggered.
Only one transmit port of the protection group is enabled and the other is disabled.
When the enabled transmit port is in the down state, disable the transmit port and enable the other transmit port.
If the second port is in the up state, a switchover is performed. Otherwise, the detection continues.
Only one transmit port of the protection group is enabled and the other is disabled.
If the port on the active board is in the down state, directly enable the port on the standby board without disabling the port on the active board.
Check whether to perform the switch over according to the weight.
The relation between the modes is as follows:
In the delay detection mode and the enhanced delay detection mode, the protection group supports only the optical port and the system supports the configuration of the duration for enabling the port on the standby board during detection.
In the delay detection mode and the enhanced delay detection mode, the system supports the configuration of the detection delay and frequency for the protection group.
In the delay detection mode and the enhanced delay detection mode, the system supports the configuration of the weight for the protection group. If multiple protection groups exist on the control board, the active/standby switchover can be performed only when the sum of weights of the protection groups in which the port on the active board is faulty and the port on the standby board is normal is greater than the sum of weights of the protection groups in which the port on the active board is normal and the port on the standby board is faulty.
The protection group in the delay detection mode is compatible with the protection group in the enhanced delay detection mode on the control board. The protection group in the delay detection mode, however, is incompatible with the protection group in the port status detection mode.
