APA: Unable to add an interface to a LinkAgg

[Jorge Zacarias_1]

Hi,

I had already configured 2 gigabit cards (lan0 and lan1) on my server using AutoPort Aggregation. But yesterday I realized that I have just one card on my link.

I followed the HP Auto Port Aggregation Quick install manual to troubleshoot this issue but I'm unable to make it work.

Here is the actual configuration:

When I try to add the lan0 interface to my LinkAgg it says that the port 0 is already in LinkAgg.
My APA config files have the lan0 included but when I check my link 900 using SAM or lanadmin I see just 1 interface.

Any advice or hints?
Thanks
Jorge

Hi, Jorge,

I suspect the lan0 is not connected. You can run "lanadmin -x 0" or "lanadmin -g 0" to check its link status.
If the link status is down, lan0 will NOT show up in the LinkAgg.
Try to bring the link up by checking the cabling or resetting the card.

Hope this helps.

Hi Xianjie,

You were right! the link was down.

#lanadmin -g 0
The link is down. The speed and other link state information
are undefined. The configuration specified for this card is:
Speed = 1000 or 100 or 10 Mbps.
Autonegotiation = On.

#lanadmin
Enter command: lan
Enter command: ppa
Enter PPA Number. Currently 0: 0
reset
Resetting LAN Interface to run selftest.

I checked with my network admin and the switch port was down. He activated the port on the switch and everything is working.
Thanks for your help.

Best Regards,
Jorge
