HP's Network Port Aggregation software

praveen.. — Fri, 31 Mar 2006 12:22:06 GMT

Hi,
My Admin had installed HP's Network Port Aggregation software on server and then Aggregate the two network cards. He is saying the work has been completed.

How can i check that this is fully implemented and working.

please let me know the commands to check this.

Thanks

Check how? If you have connectivity to the box then the basic functionality is sound. An APA (It is Auto Port Aggregation) interface will have a high "PPA" number so you would see something like lan900 in your netstat -in or -rn output.

If you want to see traffic being load balanced, run several concurrent netperf TCP_STREAM tests to different remote systems.

Hi,

A simpleset way to check this will be
#lanscan -q

It will show which physical interfaces are added to which logical interface. Also to check this if it has been configured in hot-standby mode, start pinging server and remove cable from both interfaces one by one the ping should not interrupt.

HTH,

Hi,

The last time I used it we have lan interface such as lan900 in the lanscan output.

And if you have root access you can launch a lanadmin on this "card" on obtain something like this :

Output from /usr/sbin/lanadmin -x -v 900 :

Link Aggregate PPA # : 900
Number of Ports : 2
Ports PPA : 5 18
Link Aggregation State : LINKAGG AUTO
Group Capability : 5
Load Balance Mode : MAC Address based (LB_MAC)

You can see number of ports at 2, in this case it was 2 1Gb lancards.

Hope this helps

# ifconfig lan1
ifconfig: no such interface
# ifconfig lan2
ifconfig: no such interface
#

so should i run this command:
#/usr/sbin/lanadmin -x -v 1
#/usr/sbin/lanadmin -x -v 2
#/usr/sbin/lanadmin -x -v 3

from which command I will get the information which i require to check whether this software has been installed or not and aggregation of two network cards

Please suggest

note: i dont require to make any changes, simply i need to check.

Since you don't see any APA interfaces in lanscan (lan1, lan2, etc are normal LAN cards, not APA interfaces), you don't have APA configured. I would run swlist to see if the APA software has actually been installed.

Hi,

Try this to see as Bill said if the product has been installed :
swlist -l bundle -l product |grep J4240AA

Hope this help

# swlist -l bundle -l product | grep J4240AA

NO OUTPUT FROM THIDS COMMAND.

SO IS IT INSTALLED OR NOT?

PLEASE SUGGEST

Hi ,

As Bill Hassell said, it's not configured. I've it installed and I get 5 lines.

J4240AA.HP-APA-KRN B.11.11.07 HP Auto-Port Aggregation/9000 APA kernel products.
J4240AA.HP-APA-LM B.11.11.07 HP Auto-Port Aggregation/9000 LM commands.
J4240AA.HP-APA-SAM B.11.11.07 HP Auto-Port Aggregation/9000 APA SAM product.
J4240AA.HP-APA-FMT B.11.11.07 HP Auto-Port Aggregation/9000 APA formatter product.
J4240AA.HP-APA-RUN B.11.11.07 HP Auto-Port Aggregation/9000 APA command products.

I think it's not installed. Sorry.

Hope this helps

APA does require some networking expertise to properly configure the product. Apparently the sysadmin must have installed and configured the product on another system. Note also that you need compatible switches to take advantage of APA for both failover as well as aggragation.
