I do not have the command "failover lan unit secondary" in the configuration.
But still i see the pix box shows as secondary.
ph-md-pix1# show failover
Cable status: Normal
Failover unit Secondary
Failover LAN Interface: not Configured
Unit Poll frequency 15 seconds, holdtime 45 seconds
Interface Poll frequency 15 seconds
Interface Policy 1
Monitored Interfaces 4 of 250 maximum
Let me know if any one why it is showing as secondary.
