VWire interfaces down

jcostello — Wed, 02 Nov 2011 19:28:34 GMT

I am in the process of setting up a new implementation and have not reconfigured from a base install yet other than to set up HA.

I plugged in Ethernet1/1 and Ethernet1/2 to a switch across the room, while running the cables I lost track of which was which and was trying to determine which port was which by bringing up the interfaces on the switch. However when I brought up only one of the two interfaces neither interface would come up. When both interfaces on the switch were brought up, both interfaces on the PAN would come up as well. However when I unplugged one of the interfaces, both interfaces would go down.

Is this expected behavior for a virtual wire pair for them both to go down when one of them loses connection?

PA-2050 running 4.0.7

Thanks

Check out the "link-state pass thru" option on your v-wire.

Here is the relevant quote from the documentation:

"Select this check box if you want to bring down the other port in a virtual wire when a down link state is detected. If this check box is not selected, link status is not propagated across the virtual wire."

Based upon your description it would appear that you have enabled this option.

That appears to be on in the default-vwire. Is that a default configuration?

That would do it.

thanks

My lab environment running 4.0 PAN-OS also has this option selected as the default when creating a new v-wire.
