Configuring FCIP using 2 ports per Brocade DCX switch
Hi experts,
I'm trying to connect 2 switches, 1 on each site eventually using FCIP on 2 ports per switch. So I'm trying to do this:
On the left I'm trying to use 2 physical ports with ip addresses 192.168.1.10 and 192.168.1.11 and on the right I'm using another subnet with the 2 ports using 192.168.2.10 and 192.168.2.11. There's a "cloud" between the 2 sites which routes correctly between the subnets. I've configured 1 port on each switch with an ip address and a portcmd --ping works fine. When I'm trying to add an ip address to the 2nd port I'm getting a message saying that the 2nd port cannot have an ip address in the same subnet.
What am I missing here? Should both ports on each switch be in different subnets? The commands I used are:
portcfg ipif 7/ge5 create 192.168.1.10 255.255.255.240 1500
portcfg iproute 7/ge5 create 192.168.2.10 255.255.255.255 192.168.1.1
portcmd --ping 7/ge5 -s 192.168.1.10 -d 192.168.2.10
And when I try to add 192.168.1.11 to 7/ge6 I'm getting:
portcfg ipif 7/ge6 create 192.168.1.11 255.255.255.240 1500
Subnet conflict with Slot 7 Port ge5.
IP address conflicts with subnet of an existing address
I can't find the document where it's stated how to use the ip addresses correctly.

Right, seems as if nobody has ever done this before?
The way it looks now is that each physical interface needs to be on a different subnet, but FOS7 would solve this issue and you seem to be able to have more than 1 physical interface in the same subnet. So it's a FOS restriction then.
Network operations gave me 1 subnet each containing 16 addresses for each location, so I have 16 ip addresses (13 actually since network, broadcast and default gateway need addresses too) for 2 switches. But if each interface needs to be on a different subnet I can split up the given subnet into 2 x 8 ip addresses, minus 3, leaving only 5 per location, so 2 x 2 per location (1 left), so 2 per switch of which I can only use 1, but since I now have 2 subnets I can use, I'm able to configure addresses on 2 physical ports.
I was thinking about splitting the 16 address subnet into even smaller subnets, but that would leave me with 4 addresses per subnet, each having a network, a broadcast and a default gateway address, leaving only 1 address I can use, which is fine, except that my 16 addresses now leave me with 4 usable addresses in 4 separate subnets, so I can still only use 2 addresses per switch. So cutting the subnet in half would be the better choice since it leaves a little room for future enhancements like FOS7 has.

not being familiar with Brocade long-distance technology, can you create a trunk that consists of two ports and assign just one ip address ?

Hi there,
I haven't configured many FCIP links, but I reckon that the concept of FCIP trunking is the opposite: you can merge up to 4 circuits (with 4 different IP Adresses) into a single FCIP trunk (or tunnel). I think that you cannot share an IP Address with two GigE ports.

Not in FOS 6.

I need to check which port on "FX8-24" module of DCX switch is configured for FCIP ?
Also need to check the ipaddress assigned to that port ?
Can anyone help me to know the commands to check above mentioned things ?
