NIC card Icapability

How do I find out what the NIC card capabilities are on a Alpha Server system running Tru64 Unix V5.1B?

I need to know if the NIC card is able to support 1000GB speed.

Re: NIC card Icapability

Hi Danesh,

You should be able to find out what NICs are in the machine by looking at the output of

# ifconfig -a

or

# hwmgr view hier | grep network

That will give you a device type such as, tu, ee, alt, bcm etc.

Looking at the man page for those device drivers should tell you the capability.

For example

# man bcm

"The bcm interface provides access to Gigabit Ethernet (1000Mbs) through the DEGXA device."

Hope this helps,

Regards,

Rob

The 'alt' devices also provide 1 GB speed.

Send output of:
>>> show config
and we will know what NIC card you have.

Re: NIC card Icapability

I have attached a file which displays the output of the hwmgr command, i.e.

# hwmgr -show name

# hwmgr -get attrib -id 34

# hwmgr -get attrib -id 52

Can someone explain to me which ethernet NIC card is being used in this server i.e ee0 or bmc0 ?

Re: NIC card Icapability

Hi Danesh,

You didn't attach the file...

When you do, please also post the output of

# ifconfig -a

Cheers,

Re: NIC card Icapability

Sorry about that, I have now attached the file for you to look at.

Re: NIC card Icapability

OK. The ifconfig output shows that you are currently using ee0 which is capable of 100Mb/s, although you do have a Gigabit capable card bcm0 in the machine.

Cheers,

Re: NIC card Icapability

Hi Rob,

So the ee0 NIC interface card can only support maximum speed of 100Mb/s?

The other bcm0 NIC interface is capable of running at speed of 1000Mb/s but is there anyway to check if this interface is being used?

Re: NIC card Icapability

From output of
# ifconfig -a
you can see that bcm0 is not configured.
Also do:
# sysman Networking
and check out yourself.

Re: NIC card Icapability

I followed your advice by checking with ifconfig and I also looked in the /var/adm/messages file which displayed NIC interfaces, NIC speed capability, vendor and driver versions.

Thank you all for you advice.
