I've been testing redundancy of a pair of ACE 4710 Appliances (A3(1) software) in our lab and run into a peculiarity in the FT configuration. I configure the FT exactly as in the configuration guide and it works perfectly as long as I use a cross-over cable between the FT interfaces. This is the relevant config (other ACE same apart from IP's reversed).
interface gigabitEthernet 1/4
ft-port vlan 10
ft interface vlan 10
ip address 192.168.1.1 255.255.255.0
peer ip address 192.168.1.2 255.255.255.0
ft peer 1
heartbeat interval 300
heartbeat count 10
ft-interface vlan 10
query-interface vlan 90
ft group 1
As I said - works great with a crossover cable. However, the appliances will be far enough apart that I need to use a normal switched connection and this just refuses to work (both appliances on consecutive ports on the same switch). The connections come up and there are no errors on the switch ports or the appliances, but the heartbeat packets don't seem to get through. The odd thing is that if I swap the "ft-port vlan 10" command for a normal "switchport access vlan 10" command then it works fine.
Can anyone explain this weirdness? what exactly does the "ft-port" do?
I was using a Cat3550 switch, with the ports set up as normal access ports, like this:
switchport access vlan 10
switchport mode access
So, on the ACE I tried not using "ft-port" and just used "switchport access vlan 10" which worked fine, and the FT worked as expected. As soon as I use "ft-port" it breaks until I add the "switchport trunk native vlan 10" command. What's going on here? does the ft-port command turn the FT port into a trunk port? I'm definitely missing something here and the Cisco docs are not clear on this point.
I have just setup two ACE4710's, same issue on FT connection. The reply about assigning the ft vlan to the interface is not an acceptable command.
The switches that I am using are 3750's, these are recording interface errors, and when you do a show int f4/0/47 controllers, you see the issue is related to runts, undersized packets. I have seen similar issues before on 3750's.
I have had to leave the FT connection as a cross over to make it work.
