Cant assign ip address to bcm4.0 2

[snowman50]

Hi Guys

BCM400 ver 4.0
I am trying to change the Lan2 address to 10.10.240.200./255.255.0.0
The system rejects it.

It allows me to change it but when the EM connection drops to say you need to disconect for changes to apply and i look in the lan seeting its back to the original setting.

I have rebooted it 6 times and tried changing it to another address and cant get it to change..

Lan1 10.10.10.1/ 255.255.255.0

Lan2 10.10.240.200/255.255.0.0 wont change

I told the system to obtain an address from the Dhcp network and got 10.10.170.2 but i cant change it to 10.10.240.200.

Is there some sort of conflict here with lan 1.

The old bcm1000 was able to allow this address to be entered but i now realise it has 2 seperate lan cards.

some help please

I tried it on a bcm50 and same problem but it changes the subnet to 255.255.255.0

is it a subnet issue on the lans in the BFT

A bit lost here

I had the same issue before trying to change the IP address to another address, I kept changing the IP address via Element Manager, but it never took the change.
The Element Manager just kept kicking me out on the reboot and no changes were made.
I went to the telset programming and made the change to the IP address, then it asked for a reboot. Confirm and after reboot, the IP address was installed in the system.

Good idea ,
I have done it that way before on bcm50 but forgot about that on a 4.0.

I should have guessed that but the brain went into overload when it would not work.

I think your answer lies within the subnet mask choices.

You LAN1 has a 255.255.255.0 mask, which means any address of 10.10.10.xxx where xxx is 1 through 255 (which you probably know)

Your LAN2 has a 255.255.0.0 mask, which means any address of 10.10.yyy.yyy. So, 10.10.1.1 through 10.10.255.255 is the valid range.

The problem comes that your LAN 1 address is then within the LAN 2 address space, and the Router functions with the BCM will HATE this (hence its forcing a subnet mask that prevents the chaos).

You will need to have IPs/subnets that don't overlap for it to work right. If you force it somehow, I would predict you'll end up with some odd routing errors.

I thought there would be some conflict here.

I will need to speak to the customer regarding this.

Just a thought!!!!

If i change Lan 1 to say 10.10.240.200/255.255.0.0
and lan 2 to say 10.11.11.1/255.255.255.0

would that work.
