Interface

3GISSMORACLE — Thu, 05 Jun 2025 06:41:23 GMT

Hi ,

I have 2 interfaces :e0a ( data transfering speed :100Mb/s) and vif1 (1000Mb/s)

I set up options ndmpd.preferred_interface vif1 on primary system so that when snapmirror is updated on seconary system the interface that will be used is vif1

primary> options ndmpd

ndmpd.access all

ndmpd.authtype challenge

ndmpd.connectlog.enabled off

ndmpd.data_port_range all

ndmpd.enable on

ndmpd.ignore_ctime.enabled off

ndmpd.offset_map.enable on

ndmpd.password_length 16

ndmpd.preferred_interface vif1 (value might be overwritten in takeover)

ndmpd.tcpnodelay.enable off

Besides ,

I also set Dfm options list ndmpDataUseAllInterfaces to 0

Option Value

ndmpDataUseAllInterfaces 0

My problem is while snapmirror is being updated on secondary system ,the trafic goes to interface e0a Can you please give me some advice to solve this problem or show me how to check which interface i used while snapmirror is running ?

Best regards

Tien

Assign the hostname defined in the snapmirror.conf file to your preferred interface for SnapMirror.

For Example,

In the /etc/hosts file you will see the as below:

#Auto-generated by setup Wed Mar 23 11:05:13 GST 2011

127.0.0.1 localhost

10.32.51.50 dr-fas3140a dr-fas3140a-svif

# 0.0.0.0 dr-fas3140a-e0M

# 0.0.0.0 dr-fas3140a-e2a

# 0.0.0.0 dr-fas3140a-e2b

# 0.0.0.0 dr-fas3140a-e2c

# 0.0.0.0 dr-fas3140a-e2d

On the snapmirror.conf file perform the interface level replication as below :

pr-fas3140a-svif:prod_vol dr-fas3140a-svif:pr-d_vol - 0-59/30 * * *

Hope this helps.

What is wrong with the following interface?

public interface SomethingIsWrong {

void aMethod(int aValue){

System.out.println("Hi Mom");

}
