APA configuration Problem

RAJESH GANGADHARAN — Tue, 22 Apr 2003 05:09:19 GMT

Hi
I had Installed and configured APA in N-4000 running on HP-UX 11. I had configured APA using Lan interface in core I/O and an additional PCI 10/100Tx Lan card.I had configured APA in FEC-AUTO, but the Aggregation is not happening i.e. I want both lan card in a single interface (lan100). But both the lancards are configuring as different interface (lan100 and lan101), Please let me know how to aggregate both the lan cards in same interface(lan100)

Thanks in adv
Rajesh

Hi Rajesh,

Have a look at this document.

Edit /etc/rc.config.d/hp_apaconf in order to set up the HP_APA_MANUAL_LA variable. For instance:

HP_APA_INTERFACE_NAME[0]=lan100
HP_APA_LOAD_BALANCE_MODE[0]=LB_IP
HP_APA_MANUAL_LA[0]="0,1"

that will config lan100 as an aggregate of lan0 and lan1.

You also must configure /etc/rc.config.d/hp_apaportconf

Read the instructions on those config files.

I did the same but this time none of the interfaces got configured. I am attaching the error messages. I am using a Cisco catalyst switch, and FEC is enabled for this ports at switch. Do I need to do anything more at the switch side

I can get you some more information when I get to work if you need it, but here it goes:

APA requires a patch to function correctly. I think it's called the 'APA cumulative patch' and I think there are 2 of them, depending on what version of APA you have. i.e. If you B.11.00.13 version, you need the patch that covers version 13. It's listed in the patch decription.

Here is my hp_apaconf:

HP_APA_START_LA_PPA=100
HP_APA_DEFAULT_PORT_MODE=MANUAL

# End of hp_apaconf configuration file
HP_APA_INTERFACE_NAME[0]=lan100
HP_APA_LOAD_BALANCE_MODE[0]=LB_MAC
HP_APA_HOT_STANDBY[0]=off
HP_APA_GROUP_CAPABILITY[0]=7
HP_APA_KEY[0]=
HP_APA_MANUAL_LA[0]=1,2,3,4

And one of the interfaces in hp_apaportconf:

HP_APAPORT_INTERFACE_NAME[0]=lan1
HP_APAPORT_GROUP_CAPABILITY[0]=7
HP_APAPORT_PRIORITY[0]=0
HP_APAPORT_KEY[0]=
HP_APAPORT_SYSTEM_PRIORITY[0]=0
HP_APAPORT_COLLECT_MAX_DELAY[0]=
HP_APAPORT_CONFIG_MODE[0]=MANUAL
HP_APAPORT_SPEED[0]=100FD

I am tell the group which ports to go after, and in the portconf, telling the speed and duplex. It looks like you are getting a duplexing error somewhere in there. If your switch is set to 100FD for both ports, can you hard code you lan ports here? TO be honest, I haven't played much with the auto configuration, I just did it manually. (We just made a 400MB pipe aggregate and let it go from there...)

If all else fails, go into SAM and try it from there. You may not get it to work, but something might click after you get errors from SAM...

Hope it helps

John

I'm going to guess that the APA interface did not come up for reasons realted to that duplex mismatch error.

I'm going to guess that you have hardcoded one of the interfaces to a specific duplex setting, and it does not match the settings on the other interface. Unless you _know_ that autoneg does _Not_ work with the cisco switch, I'd suggest putting everything into autoneg (switch too) and see how things go from there.

IIRC, APA wants the settings on the different NICs to be the same.
