Output of lanscan command

[mst]

Hello,

i have to configure LAN_MONITOR on a HPUX Server. This server used to have APA configured but this no longer works with our new network equipment.

When i execute "lanscan" i get an output like this:

--

I'm wondering about the "LinkAgg" entries, i would not have expected them to be there. Can this be a problem when trying to enable LAN_MONITOR ? Or can i just ignore them ?

hi;

this is the lan_monitor configuration guide...

/etc/rc.config.d/netconf file contains
INTERFACE_NAME[1]="lan0"
IP_ADDRESS[1]="192.168.1.1"
SUBNET_MASK[1]="255.255.255.0"
BROADCAST_ADDRESS[1]=""
INTERFACE_STATE[1]="up"
DHCP_ENABLE[1]=0




APA configuration

1. /etc/rc.config.d/hp_apaportconf file

HP_APAPORT_INIT_ARGS="HP_APAPORT_GROUP_CAPABILITY HP_APAPORT_PRIORITY HP_APAPORT_CONFIG_MODE HP_APAPORT_KEY HP_APAPORT_SYSTEM_PRIORITY"

HP_APAPORT_INTERFACE_NAME[0]=lan0
HP_APAPORT_CONFIG_MODE[0]=LAN_MONITOR
HP_APAPORT_INTERFACE_NAME[1]=lan2
HP_APAPORT_CONFIG_MODE[1]=LAN_MONITOR


2. /etc/rc.config.d/hp_apaconf file

HP_APA_START_LA_PPA=900
HP_APA_DEFAULT_PORT_MODE=MANUAL

HP_APA_INIT_ARGS="HP_APA_LOAD_BALANCE_MODE HP_APA_GROUP_CAPABILITY HP_APA_HOT_STANDBY HP_APA_MANUAL_LA HP_APA_INIT HP_APA_KEY"


execute these commands..


/sbin/init.d/hplm stop
/sbin/init.d/hpapa stop
/sbin/init.d/hpapa start
/sbin/init.d/hplm start



lanqueryconf -s
lancheckconf
lanapplyconf


ifconfig lan900

Thank you for your hints. But what i dont understand: What is the last command
(ifconfig lan900) for ?

Kind regards

[Ivan Krastev]

To check that everything is ok.

Ah, ok. Thank you :)

Shalom,

Recommend removing APA if not in use.

License and support are not cheap, so you can save support costs as well.

Sorry, i dont understand. I thought both LAN_MONITOR and APA are in one product - just different modes ?

[Hasan Atasoy]

if you use apa ;
a virtual lan card is configured ( lan900,lan901... ) . and your physical ethernet cards bounded to this card.

As others have indicated, these linkaggs are normal when APA is installed, and yes, Lan Monitor is part of the APA software.

By default, there are actually 50 of these linkaggs set aside in the kernel, and lanscan does you the favor of only displaying the first 5 unless you actually have more than that configured. Other software products, glance for example, show all of them. This long unused list can be a bother, so there is a configuration parameter HP_APA_MAX_LINKAGGS in the /etc/rc.config.d/hp_apaconf file to limit them to whatever number you like.

Thank you all very much for your efforts!
