根据运行模式来划分
The two units in a failover configuration must have the same hardware configuration. They must be the same model, have the same number and types of interfaces, and the same amount of RAM.
 
1.Active/Active Failover
 

Active/active 有什么优势?

1.2个units都可以承载流量,可以实现负载分担
2.将context划分成成逻辑的 failover groups,最多创建2个group, admin和unassigned contexts 都在group1
3.Active/active只能在multiple context mode下使用
 

根据状态划分 Regular and Stateful Failover

 
1.Regular Failover
session会断开连接
 
2.Stateful Failover
session不会断开连接
 
 
根据Failover连接方式划分
 
1.Cable-Based Active/Active Failover
Specify the interface to be used as Stateful Failover link:
hostname(config)#failover link if_name phy_if
 
In this example, the Ethernet2 interface is used to exchange the stateful failover link state information.
failover link stateful Ethernet2

 
2.LAN-Based Active/Active Failover
Enable LAN-based failover:
hostname(config)#failover lan enable
 
Designate the unit as the primary unit:
hostname(config)#failover lan unit primary
 
Specify the failover link:
PIX1(config)#failover lan interface LANFailover ethernet3
