How to know if I'm using Fiber channel for lan?

[mogiro]

Hi,
It´s a simple question... I know. I suppose that it depends on the driver you use, but I want to be sure.
Some data you will need:
Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI
Path Address In# State NamePPA ID Type Support Mjr#
0/0/8/1/0/4/0 0x00306EF346C8 0 UP lan0 snap0 1 ETHER Yes 119
1/0/1/1/0/4/0 0x00306EF326D5 1 UP lan1 snap1 2 ETHER Yes 119
1/0/4/1/0 0x00306E04D0C2 2 UP lan2 snap2 3 ETHER Yes 119

lanadmin for lan0
PPA Number = 0
Description = lan0 HP PCI Core I/O 1000Base-T Release B.11.11.24
Type (value) = ethernet-csmacd(6)
MTU Size = 1500
Speed = 100000000
Station Address = 0x306ef346c8
Administration Status (value) = up(1)
Operation Status (value) = up(1)
Last Change = 100
Inbound Octets = 1893669342
Inbound Unicast Packets = 2367323276
Inbound Non-Unicast Packets = 73242968
Inbound Discards = 0
Inbound Errors = 23
Inbound Unknown Protocols = 2476521
Outbound Octets = 4150163247
Outbound Unicast Packets = 1426348812
Outbound Non-Unicast Packets = 10414289
Outbound Discards = 0
Outbound Errors = 0
Outbound Queue Length = 2
Specific = 655367


If you need further data, don´t hesitate to ask for.
Thanks in advance.

Hello,

Two following commands would be more helpful:

ioscan -fnC lan
laninfo

The following results of the above commands were gathered on one SuperDome vPar
running HP-UX 11.11. You can
easily detect the FC LAN card :)

lan 0 7/0/0/1/0 btlan CLAIMED INTERFACE HP PCI 10/100Base-TX Core
lan 1 7/0/2/0/0 btlan CLAIMED INTERFACE HP A5230A/B5509BA PCI 10/100Base-TX Addon

Your LAN 0 is 1000Base-T Ethernet card
(not FC).

hi all:

In out of ioscan you can see product number of lan card. YOu must loook for this product number y part surfer of HP for a full description


i holp help you

[mogiro]

Hi,
First of all, here you've got the ioscan -fnClan :
Class I H/W Path Driver S/W State H/W Type Description
==========================================================================
lan 0 0/0/8/1/0/4/0 igelan CLAIMED INTERFACE HP A6794-60001 PCI 1000Base-T
lan 1 1/0/1/1/0/4/0 igelan CLAIMED INTERFACE HP A6794-60001 PCI 1000Base-T
lan 2 1/0/4/1/0 gelan CLAIMED INTERFACE HP A4926A PCI 1000Base-SX Adapter


I've looked for this PN at parts Surfer, and the description is PC Board (Interface) : LAN/SCSI core I/O PCI board (Procurium).
I know that core I/O lan is not fiber, but have you got a description example of a fiber lan card?
Thanks!!

1000Base-T means gigabit on (unshielded) twisted-pair, i.e. copper cable.
1000Base-SX means gigabit on multi-mode fiber.
These identifiers are visible in your ioscan output.

For more information, see:
http://en.wikipedia.org/wiki/Gigabit_Ethernet

All these are variations of Ethernet, and that's why your lanadmin command says:

Type (value) = ethernet-csmacd(6)

Note that Ethernet-over-fiber is *not* the same thing as FibreChannel.

FibreChannel is an entirely different different family of networking protocols, which is mainly used for storage networking (SAN). However, TCP/IP *can* be run over FibreChannel too - it just isn't done very often.

In HP-UX, FibreChannel interfaces would be displayed with "ioscan -fnCfc", not with "ioscan -fnClan".

>>How to know if I'm using Fiber channel for lan?

I did not even know you could use FC for a LAN interface. Sure for a storage interface (SAN) but for IP traffic ( LAN ). I don't think so.

[VK2COT]

Hello,

In your case, your Ethernet-over Fibre card is:

lan 2 1/0/4/1/0 gelan CLAIMED INTERFACE HP A4926A PCI 1000Base-SX Adapter

Matti is right about FibreChannel, but you
do not seem to be using it :)

Number of my large telecom customers use
1000Base-SX Adapter cards.

mogiro,

from your ioscan and ifconfigs you posted you can see that

lan 2 1/0/4/1/0 gelan CLAIMED INTERFACE HP A4926A PCI 1000Base-SX Adapter

this is the fibre lan card as already stated. This also could be in use as your original post shows the software state as up

1/0/4/1/0 0x00306E04D0C2 2 UP lan2 snap2 3 ETHER Yes 119

you can see that the hardware paths are the same.

so check with lanadmin/ifconfig on lan2 or sam to check its netwrok settings

Hi,
Thanks to all you for your answer, now it is clear for me. I didn't know that Fiber Channel was a mass storage protocol, I thought it was a type of card...
Points assigned for all you!!
