How Can I Ensure That Critical Data Is Preferentially Replicated?

0

InfoReplicator supports directory-based asynchronous remote replication and allows you to use traffic control and bandwidth limit to improve the overall replication performance. However, this feature cannot identify the importance of data.

When the critical data and common data reside in the same primary directory, the system automatically detects and replicates the changed data but cannot preferentially replicate data.

Therefore, you are advised to sort out critical data before replicating it and store the data under specific directories for separate management. Then, you can add these directories to replication pairs and set a high transmission rate for the pairs to raise the pair priority. In this way, critical data can be preferentially replicated.

How to configure the critical VLAN function on S series switches
During 802.1x authentication, when a fault occurs on the network between the access device and the authentication server or the authentication server fails, the authentication process on the network is interrupted. As a result, a user fails authentication and cannot access network resources. You can configure the critical VLAN function to solve this problem. When a fault occurs on the network between the access device and the authentication server or the authentication server fails, an 802.1x authentication user is added to the critical VLAN, and then can access resources in the critical VLAN. Configure a critical VLAN on S series switches (except the S1700) as follows: - Perform the following operations in the system view: [HUAWEI] vlan batch 20 [HUAWEI] undo authentication unified-mode //Skip this step on switches running versions earlier than V200R005C00. [HUAWEI] dot1x enable [HUAWEI] interface gigabitethernet 1/0/1 [HUAWEI-GigabitEthernet1/0/1] port link-type hybrid [HUAWEI-GigabitEthernet1/0/1] port hybrid untagged vlan 20 //The critical VLAN takes effect only for hybrid or access interfaces added to the critical VLAN in untagged mode. [HUAWEI-GigabitEthernet1/0/1] quit [HUAWEI] dot1x enable interface gigabitethernet 1/0/1 [HUAWEI] dot1x port-method port interface gigabitethernet 1/0/1 [HUAWEI] authentication critical-vlan 20 interface gigabitethernet 1/0/1 - Perform the following operations in the interface view: [HUAWEI] vlan batch 20 [HUAWEI] undo authentication unified-mode //Skip this step on switches running versions earlier than V200R005C00. [HUAWEI] dot1x enable [HUAWEI] interface gigabitethernet 1/0/1 [HUAWEI-GigabitEthernet1/0/1] port link-type hybrid [HUAWEI-GigabitEthernet1/0/1] port hybrid untagged vlan 20 //The critical VLAN takes effect only for hybrid or access interfaces added to the critical VLAN in untagged mode. [HUAWEI-GigabitEthernet1/0/1] dot1x enable [HUAWEI-GigabitEthernet1/0/1] dot1x port-method port [HUAWEI-GigabitEthernet1/0/1] authentication critical-vlan 20
