Are you saying that those syslog messages showed up only right after you
connected interface 7?
 
Would you have all the syslog messages from the secondary during that
time?

Hi , yes the interface 7 is connected to the primary pix by crossover
cable.
 
This interface is connected only back-to-back without traffic internet.
 
No, i didn't reboot the primary, but this morning i riceived the alert
messages for " Lost Failover communications with mate on interface 7"
and after i connetced on the pix and i 've seen this mistake.
 
I attached the show failover and show interface :

How is the interface 7 on your secondary connected to that of your
primary? Via a crossover cable, a switch, or a hub?
 
What is interface 7 for? Your outside interface?
 
Did the primary reboot?
 
"show failover" and "show interface" output would be helpful.

Hi ,
        i' ve a problem with the pix 535.
 
Sometimes (2 times) the secondary pix (license failover) with status
Standby , losts comunication on interface X and goes in Testing.
The interface X is back -to-back with the primary pix with status Active
:
 
%PIX-1-105005: (Secondary) Lost Failover communications with mate on
interface 7
 
After the secondary monitoring the others interfaces :
 
%PIX-1-105003: (Secondary) Monitoring on interface 3 waiting
%PIX-1-105003: (Secondary) Monitoring on interface 6 waiting
%PIX-1-105003: (Secondary) Monitoring on interface 2 waiting
%PIX-1-105003: (Secondary) Monitoring on interface 5 waiting
%PIX-1-105003: (Secondary) Monitoring on interface 0 waiting
%PIX-1-105003: (Secondary) Monitoring on interface 4 waiting
%PIX-1-105003: (Secondary) Monitoring on interface 1 waiting
 
Why does the pix work so ?
Which is or are problem/s ?
 
I thought the connectivity (network), but the interface is back-to-back.
I thought the cable, it doesn't work.....but i change the cable.....
 
I've seen the logs and i didn't find nothing interesting .
Can anyone help me ?

Thanks in advance,

Roberto Paoletti
