Network adapter redundancy

[Ezra V. Isacco Di Biase]

Hi all,

I have an es40 box with 4 network adapter.
I know It is possible to have redundancy on this adapters. How can I do this?

Thanks.

You configure netrain.
Information on how to configure can be found in network administration book
under basic connections

Depending on the OS you can either use netrain or lag (link aggregation).

man nr
man lagconfig

Hi,

I tried to use NetRain with 2 device not yet configured and the system replies:

ifconfig: ioctl (SIOCIFADD): Device Busy

Thanks for your help.

it seems lat is still configured within the kernel. Check if latcp -d gives an output and if so deactivate it:

# autosysconfig list

if lat will be listed

# autosysconfig delete lat

reboot system.

If lat is not listed be sure the devices are switched to "down".

# ifconfig ee0 down
# ifconfig ee1 down
# ifconfig nr0 add ee0,ee1
# ifconfig nr0 10.0.0.1 netmask 255.255.255.0
# ping 10.0.0.1
