I have a few servers - some running solaris 9 and others solaris 10.

The nic cards installed are all running 100 Full Mb on the interfaces currently.
I would assume that all the cards are capable of running Gigabit as the are relatively new servers (under 18 months) - sun fire v490s or v440s but how can I check what NIC cards they are and what they are capable of ?

on solaris 10 you can use:

dladm show-dev
dladm show-link

Do you get what you need out of prtconf -D ??

Doesnt dladm just show me what current settings are?
I need to check to see what NIC is actually capable of... here is the output of the dladm command on my solaris 10 box... can I do same on solaris 9?
Is it possible that even though its set at 1000mb - that the NIC is not capable of this speed? (I am particularly interested in ce4)


# dladm show-dev
ce0 link: unknown speed: 1000 Mbps duplex: full
ce1 link: unknown speed: 1000 Mbps duplex: full
ce2 link: unknown speed: 0 Mbps duplex: unknown
ce3 link: unknown speed: 0 Mbps duplex: unknown
ce4 link: unknown speed: 100 Mbps duplex: full
ce5 link: unknown speed: 0 Mbps duplex: unknown

# dladm show-link
ce0 type: legacy mtu: 1500 device: ce0
ce1 type: legacy mtu: 1500 device: ce1
ce2 type: legacy mtu: 1500 device: ce2
ce3 type: legacy mtu: 1500 device: ce3
ce4 type: legacy mtu: 1500 device: ce4
ce5 type: legacy mtu: 1500 device: ce5




Also - output of prtconf -D below

you can try the following

# kstat ce0
   --- lots of output here ---
and get a list of attributes about the interface.

# kstat -p bge:0::link*
bge:0:mii:link_asmpause 0
bge:0:mii:link_duplex   2
bge:0:mii:link_pause    0
bge:0:mii:link_up       1
bge:0:parameters:link_autoneg   1
bge:0:parameters:link_duplex    2
bge:0:parameters:link_rx_pause  0
bge:0:parameters:link_speed     1000
bge:0:parameters:link_status    1
bge:0:parameters:link_tx_pause  0

# ndd -get /dev/bge0 link_speed
1000

ndd -set /dev/ce instance 0
ndd -set /dev/ce adv_1000fdx_cap 0
ndd -set /dev/ce adv_1000hdx_cap 0
ndd -set /dev/ce adv_100fdx_cap 1
ndd -set /dev/ce adv_100hdx_cap 0
ndd -set /dev/ce adv_10fdx_cap 0
ndd -set /dev/ce adv_10hdx_cap 0
ndd -set /dev/ce adv_autoneg_cap 0

this should force 100fdx for ce0 or you can always do the equiv in /etc/system with sets. just change according to what you want.
