network interface port

[gb karki]

Hi Expert,

I want to do failover test in APA configuration through command line.

Means:- i want to test lan0 and lan2.
how to do that.
i have tried.
#ifconfig lan0 down
nothing is happening.
# ifconfig lan0 up
up: Device busy


current status:-
# nwmgr

[Torsten. · Accepted solution]

It's maybe much easier to disable the port on the network switch ...

[Tim Nelson]

you could also try resetting the NIC via lanadmin

[gb karki]

I'm siting in remote location.

could you please provide me lanadmin steps.

[Torsten.]

That's why I did not say pull the cable, but disable the port.

;-)

Hi Torsten,

How can do that, do you have any documents.

[gb karki]

Hi Tim,

I have tried reset options.

#lanadmin -r 0

failover is also happened but logs are not generating.

root@mm1ciwtb:/var/adm/syslog # lanscan -q

900 2 0

>> How can do that, do you have any documents.

Sure. But what switch do you have?

[gb karki]

No, I don't have.

[Torsten.]

Sure you have. Where is the other end of the LAN cable plugged in?

;-)

[rick jones]

WRT using ifconfig - all ifconfig does is manipulate "interfaces" - constructs in the mind of IP. It will cause the IP and ARP SAPs to be bound (or unbound if you unplumb) from the driver (DLPI). It does not actually affect the NIC itself.

[gb karki]

Hi Torsten,

I think, other end is connected to switch.

[Torsten.]

So why not disable the related port on this switch?

[gb karki]

I don't know the network people even i don't the respective port no in switch.

just we are trying through server using command line.

is it posible?

[Torsten.]

At first it would be nice to know the current configuration and status:

# nwmgr -A all -c lan900

# nwmgr -S apa

# nwmgr -v -c lan900

# model
