Define ELAN on ATM Card

[David du Plessis]

Have defined an el100 on my atm card and it works well. But now on defining a second el, say el200 that must connect to the same LECS and ELAN name, it will not work. The LEC Selector must be different than the on for el100. But when I do a netstat -in the el200 is not displayed, also with elstat -n el200 -v it says that it is not operational. Please help me!

Hi David,

I'm not certain this will work the way you are trying to set it up. What is your goal for adding el200? If you have an ELAN going to the same LECS already what is the goal of setting up another ELAN to the same LECS? If you are just looking for another IP you can assign an additional virtual IP to el100:1 for example.


Here is the ATM documentation link if you don't have it.

Hope this helps,

Hi Todd

I can use the method you suggest but I am not sure on how to assign another IP address to and exsisting elan. If you could give me some tips I would appreciate it greatly.

Thanks

Hi David,

I tested this on my system. All you need to do is define the virtual interface in /etc/rc.config.d/netconf file. The atm software is started prior to the netconf file is read, so adding the virtual IP to the netconf will do the trick. You dont need to put the el100 in the netconf, thats taken care of via the ATM configuration just add any additional virtual IPs you want to configure.

My Config:

netstat -in
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
el101:1 1500 10.10.5.0 10.10.5.240 0 0 0 0 0

/etc/rc.config.d/netconf
