Re: PIX 515e with FO not working

Hello atul_dalvi,

Can you post "sh fail" output from this device. It looks like it is the standby Pix. Did you try doing this on the other Pix?

Hope that helps! If so, please rate.

Re: PIX 515e with FO not working


This unit is a licensed with fail over only.

You need to connect it to unrestricted device and then configure it form the primary node.

you can check which one is the primary by typing the folloing command: show failover

Or, in case you have Pix cluster bundle (FO + UR) properly connected, you can force switch between primary and failover nodes by typing the this command:

failover active

you also need to remember that when you change configuration and write it to the startup config, you need to replicate the configuration to the failover device too.

I hope it helped...
