LAN cabling

[Jayraj]

Hi,

I have 3 ports available on my server. lan 0 is configured as Production.lan1 and lan2 are free, however one of these ports has been cabled. But how to know which port is cabled. Is there any command to check whether the port is cabled or not..

Hi,

check with linkloop command. for more information see man linkloop

linkloop â i
Link connectivity to LAN station: 0x00108318AFED

# linkloop â i 2 0x00108318AFED

Hi,

you could use also lanadmin :

#============================================
must be up :

Administration Status (value) = up(1)
Operation Status (value) = up(1)

Enter command: display

Hello Swaraj,

To check the physical connectivity you can use linkloop command.
Eg.
# linkloop -i 2 0x00108318AFED
Link connectivity to LAN station: 0x00108318AFED
--- OK ----

Note: Here, lan instance of one server is 2 and the MAC addr of the required server is 0x00108318AFED.

Regds,
R.K.

Hi,

If you only need to know the cable connectivity for lan1, find out it's mac address then use linkloop like below.

#lanscan |grep lan1
0/3/0/0 0x00403E0470B5 1 UP lan1 snap1 6 ETHER Yes 119

#linkloop -i 1 0x00403E0470B5
Link connectivity to LAN station: 0x00403E0470B5
-- OK

Cable is connected you will get the above output. If there is no cable you will get the below output.

Link connectivity to LAN station: 0x00306E5EAA46
error: expected primitive 0x30, got DL_ERROR_ACK
dl_error_primitive = 0x2d
dl_errno = 0x04
dl_unix_errno = 57
error - did not receive data part of message


You can also check the physical cable connectivity between lan1 and lan2(or with any card on any server). For that you need to use the same linkloop command with destination mac address. For examaple to check the connectivity between lan1 and lan2,

#linkloop -i 1

Shalom,

The card itself is normally stamped, unless its a very old network card.

lanscan will show you linked ports and can be run after cable connection so you are sure which has been cabled.

Many older versions of HP-UX will not tolerate two NIC cards/ports on the same system configured on the same network.
