I've been trying to connect a Finisar Passive tap (I've used the old Shomiti century taps and now the new UTP IL/1 tap) to a Firewall and my Catalyst 4006. The tap is advertised as being fault tolerant, but when I use it in conjunction with the 4006 I am getting delays of about 25-30 sec before my connection comes back after power is pulled from the tap. I've tried different configurations on the port (forcing full duplex, port fast enable/disenable, etc...), but I can't seem to drop the delay any lower. I need it to be 10 sec or less. The tap and firewall work fine when connected to a 6509, but the 4006 is giving me trouble. Has anyone else had this problem?
