Danny,

Please check the documentation at http://www.cisco.com. Based on your "Both PIX Fw is setup with..." description it doesn't sound like you have properly configured the PIXen for failover.

Liberty for All,

Brian

Subject: [fw-wiz] RE: PIX FW Failover & Hello Packet

Hi PIX expert
I need help...

I have 2 PIX 515 fws and setup both of them to run as failover, and also I
have put the ACL on each interface except "Failover" interface. For some
reason after failover cmd is turned on for few minutes, then for awhile the
Standby PIX failed, and it keeps checking all the interfaces.

The question is: The "hello" packet that PIX fw sends to all the interfaces,
is it multicast or Cisco proprietary like Cisco CDP or something else?

Is it possible the ACL blocks the communication when PIX tries to send the
"hello" packet, and then it fails?

Both PIX Fw is setup with 2 cables, and all the interfaces are plugged in to
the switch that does not have trunking, etc.
The inside int is connected to diff switch from the other 3 switch, and only
these 3 int are in a waiting mode (waiting for hello packet), but not the
inside interface and failover int.

Any idea?

Thanks
Danny
