I'm setting up 2 ASAs in failover mode. For added availability I'm using Redundant interfaces.
Ethernet0/0 is a 1Gbps interface
Ethernet0/2 is a 100Mbps interface
Both are combined into Redundant1
The same is ddone for the other 2:
Ethernet0/1 is a 1Gbps interface
Ethernet0/3 is a 100Mbps interface
Both are combined into Redundant2
I use 2 contexts, and each context has it's own Redundant interface
(All other interfaces are through the 4-port RJ45/SFP module).
In both Redundant inrterfaces, the 1Gbps is the primary, and the 100Mbps is the secondary interface.
When configured, all works as expected.
When I disconnect the 1Gbps link, a switchover occurs to the secondary (100Mbps) link. Connectivity is maintained.
When I reconnect the 1Gbps link, there is NO switchback! (like the preempt option with context failover).
Ofcourse I prefer the 1Gbps link to be active.
Is there a way to accomplish this?
If not: Is there a SNMP way to monitor this? (I now about the show int Red1 | grep Member and redundant-interface red1 active-member e0/0 commands).
Looking forward to your reply,
