Sidewinder firewall with two 3750 Switches

Hi Folks,

I have two sidewinder firewalls connected to two 3750 switches.

The sidewinder is creating a virtual IP address and a virtual MAC, unfortunately the switches are not able complete the ARP for this virtual IP.

Once we do a static arp, things goes fine.

the question is : Any one have any idea of what is going on? any one had the same scenario before?

I thank your cooperation in advance

Ismail

Can you check by disable CDP on switch.

Which IOS do you have?
