Curently we are using 121.100.32.254 as ipv4 addess.

we login to the sever using the above ip.

but my requirement is ,

We have to configure one more ip which do not belong to 121 segment.

is it possible to configue two ipv4 ip?

Do you have more NICs or do you want to use the same?

Hi

Do you have more NIC ??

How can I check it.

model :rp 3440.

do you want to use the same ??

Can You explain me ,How can I use the same ?

[Patrick Wallek]

There are several ways to see how many NICs you have:

# lanscan

# ioscan -kfnC lan

To see what is in use you can do:

# netstat -in

Post that output and we can proceed from there.

Looks like there are 3 NIcs, but only 1 configured.

Sure this is a rp3440?
The hardware paths look different.

Please run

# model

again.

However, connect a cable to the free slot of the second OCI card and use SAM to configure an IP address.

I pasted the wrong output.

------Looks like there are 3 NIcs, but only 1 configured.

How you are saying this,Can you explain me.

[Torsten.]

Do

# ifconfig lan0

#ifconfig lan1

#ifconfig lan2

# netstat -in



Path 0/3/1/0 is the second from top slot,
path 0/4/1/0 is the top PCI slot,
path 0/1/2/0 is core I/O.

hi,

Yes,I can confirm that lan1 and lan 3 are free.so two nic are free and one is used

I have below diubts ..

when i checking with ioscan -kfnC lan

in the "Driver " status is as igelan and iether.

what is the difference in it ?

so I can use any of the remaining two nics ?

but will there be any impact if I have two ip for same server ?

[Torsten.]

There are differnt chips used, hence different drivers.
