How to check which NIC is in use for the backup on client while backup running?

Hi Experts

We have few unix servers configured in Netbackup for backup , and for backup we want to use dedicated Backup VLAN (10.240.60..xxx) , We know how to configure it , but same as windows we want to check whether it using the NIC we want to.
Generally  in  windows , we specify the backup vlan IP  in master server host file and while backup running , On client  via Task Manager >Networking,  we make sure via which NIC backup is running though , But in UNIX , we can't check which NIC data is going through.

Experts, Please advise.

use the netstat command in linux to see the traffic and ports in use

I hope this helps !

netstat -rn will display the routing table.
If the IP of the server is in the same segment as the second NIC this is the path the traffic will take otherwise it will take the default route/gateway path.

if the system interface for backup is on the same VLAN / subnet on which the backup server is, then the backup will be going through that interface (unless the two interfaces of the system are on the same subnet, which is not recommended). If the backup server is on other subnet, then make sure that routing table has entry to route traffic to router on the vlan / subnet of the backup interface.

Try to run the following:


route -n

It will show you networks and their gateways, i.e. routes that they will take.

Good Luck!

Simply issue several times consecutively

netstat -i

and watch which interface's RX and TX values are growing significantly.

Guys
Thanks for all support and reply.
The best way I found to find while or while not backup running is via  
UNIX : /usr/openv/netbackup/bin/admincmd/bptestbpcd -client <client name>  or
Windows: /.../veritas/netbackup/bin/admincmd/bptestbpcd -client <client name> { run on master server}, which tell what NIC ip from master server it talking to NIC ip on client.
BUt Netstat tells partially like what NIC ip it talking or connecting on client.  that is  netstat -a | grep -i vnet
But I am happy to give poitns for netstat repliers.

Thanks again
