Shulou Source: shulou.com Published: 2022-06-01 03:13:45 09月14日 Update

Conditions for failover:

1. The hardware model must be the same

2. The system version must be consistent.

3. The model must be consistent.

4. The same number of licenses and licenses

Steps:

Step 1: configure failover interface to ensure status up

LZ-CNC-UTM (config) # failover lan interface Beat G2

Step 2: configure the device to be the Active role

LZ-CNC-UTM (config) # failover lan unit primary

Step 3: configure failover link

LZ-CNC-UTM (config) # failover link Beat G2

Step 4: configure authentication key, optional

LZ-CNC-UTM (config) # failover key 0 cisco

Step 5: configure failover interface ip addr

Failover interface ip Beat 10.0.0.1 255.255.255.0 standby 10.0.0.2

LZ-CNC-UTM (config) # failover

Step 6: configure the above on the standby role, the role is

ASA-2 (config) # failover lan unit secondary

Step 7: wait for synchronization, and use sh failover state to view roles after synchronization is completed

Test:

Simulated Active device failure, standby switchover

Network communication is always normal, as follows:
