Different interfaces need to be declared with different LNET networks - something like "networks=tcp0(eth0),tcp1(eth1)". Of course, that assumes your clients are configured to use a mix of tcp0 and tcp1 for connections (with each client only using one of the two). This is really only useful in corner cases, when you're doing something strange; if eth0 and eth1 are in the same subnet (as in your example), this is almost certainly not productive.<div>
<br></div><div>A better bet might be to use a single LNET, and bond the two interfaces together - either as an active/passive pair, or active/active (e.g., LACP). Then you'd declare networks=tcp0(bond0), give the bond a single IP address, and client traffic would be split across the two members in the bond more like you probably expect (given the limits of the bond protocol you're using).<br>

<div>hello friends,</div>
<div> </div>
<div>I need to comunicate my OSS by two ethernet TCP interfaces: eth0 and
eth1.</div>
<div> </div>
<div>I have configured this feature in my modprobe.d with:</div>
<div> </div>
<div>“options lnet networks=tcp0(eth0,eth1)”</div>
<div> </div>
<div>And I can see two interfaces with: </div>
<div> </div>
<div>lctl --net tcp interface_list</div>
<div><a href="http://sa-d4-01.ceta-ciemat.es" target="_blank">sa-d4-01.ceta-ciemat.es</a>: (<a href="http://192.168.11.15/255.255.255.0" target="_blank">192.168.11.15/255.255.255.0</a>) npeer 0 nroute
2</div>
<div><a href="http://sa-d4-01.ceta-ciemat.es" target="_blank">sa-d4-01.ceta-ciemat.es</a>: (<a href="http://192.168.11.35/255.255.255.0" target="_blank">192.168.11.35/255.255.255.0</a>) npeer 0 nroute
0</div>
<div> </div>
<div>But, the clients only can communicate with the first interface:</div>
<div> </div>
<div>lctl ping 192.168.11.15</div>
<div>12345-0@lo</div>
<div>12345-192.168.11.15@tcp</div>
<div>lctl ping 192.168.11.35</div>
<div>failed to ping 192.168.11.35@tcp: Input/output error</div>
<div> </div>
<div> </div>
<div>Any suggestions how to “enable” the second interface?</div>
<div> </div>
<div> </div>
<div>thank in advance</div>
