Re: Configuing double ipv4

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.

Re: Configuing double ipv4

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.

Hope this helps!

Torsten.

Re: Configuing double ipv4

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.

Hope this helps!
Regards
Torsten.

Re: Configuing double ipv4

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 ?
