Determine if NIC can run on Gigabit network

I have a bunch of Solaris servers that will be moved to a gigabit network connection. How do I view the network settings on the network cards and determine if they can run on gigabit network? What commands I can use? This will help me if my group has to purchase new network cards. Thanks for you help.

Usually just knowing the driver for the hardware is enough. You don't mention what type of hardware you have (SPARC or x86).What are your interface names?-- Darren

Out of seven servers, 6 serves have bge0 interfaces and one with hme0. The hardware platforms are all SPARC.Message was edited by: DCMetroSunAdmin

That will mean you have six systems with 10/100/1000 hardware,and one system with 10/100 hardware.They can all "run" on a Gigabit network, but the maximum transfer speedinto and out of each chassis is based upon the chipset designs of the interface.

Thanks for your input. So how do I go about finding the chipset designs of the interface using unix commands in order to determine the maximum transfer speed?

Well, you might be able to use 'ndd -get /dev/<int> ?' and make some guesses based on the available attributes. But I'm not aware of any API that you can use to query the capabilities of the network hardware.

Building a table on your own and populating it with the possible hardware choices may be simpler.

You can also trawl the Sunsolve support web site for Infodocs,

and spend time at Docs.Sun.Com and the Sun System Handbook, as well.

Generally, you just need to "know" your hardware.

Your newer systems will likely have a gigabit interface inside,

while the older systems will only have 10/100 chipsets for connectivity.

Your bge interfaces tell me those are newer systems,

with a Broadcom Gigabit Ethernet chipset.

hme is a 10/100 chipset that was widely use in a previous generation

of Sun's SPARC-based systems. ( Highspeed Media Ethernet )
