MAC address

[screwloose]

How do you get the MAC address on Solaris 9?

On AIX I would use lscfg -vl <adapter>; what is the command on Solaris?

 

[screwloose]

ifconfig shows it. Hmm, AIX's ifconfig doesn't show the ethernet address.

Okay, I have a different question now.

If the device ce2 has a MAC address and then you have another device ce2:1, it doesn't show a ether address. Is the MAC address for ce2:1 the MAC address of ce2?

Thanks.

yes

Hi,

You can have eatch NIC use its own MAC address. Use eeprom to set the value of local-mac-address? to true.
local-mac-address?=true

Can you also use eeprom to display MAC addresses?

no, usually (onboard) NICs derive thios from the hostid...

eg.:
# hostid
80f00312
# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000 
hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 10.43.50.43 netmask ffffff00 broadcast 10.43.50.255
        ether 8:0:20:f0:3:12 
hme0:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 10.43.50.58 netmask ffffff00 broadcast 10.43.50.255

Is there a way to see what speed the NIC is operating in (10 half duplex, 100 Full Duplex....)?

Thanks!

Yes, use the following command;

ndd -get /dev/<NIC>

for example;

ndd -get /dev/ce0

 

[bfitzmai]

The commands for ndd are as follows. We will use the same device in the example as comtex17.

As root:

ndd -get /dev/ce link_speed 0 - 10 Meg
1 - 100 Meg
1000 - 1 Gig

ndd -get /dev/ce link_mode 0 - Half Duplex
1 - Full Duplex

You can find out what device you are using by looking at the name of the file /etc/hostname.***. So if your file name is /etc/hostname.eri0, you will use the command:

ndd -get /dev/eri link_speed
ndd -get /dev/eri link_mode
