Trying To Determine Which LAN is in use

[B Wade Moll]

I have a server at a remote site that has one lan cable plugged into what is labeled on the server as SLOT 2 & the lan cable is connected to the bottom port. The server has 5 nic cards. three are dual port nics, followed by 2 nic's that have a fiber port & a rj-45 port.

ioscan shows the following:

root@visccov1:/root>ioscan -kfnC lan

I BELIEVE the connection is on lan4. Can someone look at this and possibly confirm that?

Thank you :)

Hi ,

Can you Check with "linkloop"

Example:-

# linkloop 0x00306E461911
Link connectivity to LAN station: 0x00306E461911
error: get_msg2 getmsg failed, errno = 4
-- FAILED
frames sent : 1
frames received correctly : 0
reads that timed out : 1

or please check ,

more /etc/rc.config.d/netconf ,

Thanks,
Johnson

how does it says..?

hope you have fail-over lan Cards configured

# A IP address, subnet mask pair uniquely identifies

#
# Precedence rules:

There is only the one lan cable plugged in right now. Our networking team is still setting up a 2d switch. I just ignited the box yesterday and trying to get it up on the one lan.

Looks Lan4 --> is in Use, for more information , can you help to attahe /etc/rc.config.d/netconf file will exaplain you clearly,

Thanks,

I agree and it's why I configured lan4. Darn thing doesn't want to ping the gateway though...

Its Confirmed that LAN4 is only configured, in your server

Yes, I configured lan4 based on the description of the slot the cable was plugged into at the remtote site by a technician I asked to tell me where the cable was plugged into.

I'm trying to determine if that's the lan which it's plugged into based on the ioscan and lanscan hardware addresses

[Johnson Punniyalingam]

>>>>I'm trying to determine if that's the lan which it's plugged into based on the ioscan and lanscan hardware addresses <<

ioscan --> will only show the device "claimed or not sorry not the connectivity. :(

lanscan --> Yes you can

For example if you have NO LINK on the lan4 probaly you "lanscan" --> output will show like below

lan4* 1500 138.35.86.128 138.35.86.151 22886 0 22886 0 0
(pls take note (*)--> means link down, or no link,
