On any distro release, the lsqeth utility from the s390-tools package can display the card_type. This attribute contains the link speed, but only for real OSA, i.e. dedicated / direct-attached to z/VM guests. In my following example, I used a dedicated OSA with 1Gbps Ethernet. # lsqeth Device name : eth0 --------------------------------------------- card_type : OSD_1000 ... Please find documentation of possible card_type values in http://public.dhe.ibm.com/software/dw/linux390/docu/l26edd01.pdf, "qeth" chapter (page 107) -- or alternatively any other recent device drivers book (the older version matching SLES 10 did not yet document the card_type attribute). If you use virtual OSA, i.e. through z/VM VSWITCH, then you would have to check the link speed of the VSWITCH uplink OSA(s) (RDEV(s) and/or portgroup) under z/VM. I don't know which source velocity uses to determine the network (link) speed, but the above described method should provide reliable information directly from the qeth device driver. > -----Original Message----- From: Linux on 390 Port > [mailto:[email protected]] On Behalf Of Mark Post Sent: > Wednesday, December 22, 2010 5:58 PM To: [email protected] > Subject: Re: ethtool and SLES10SP2 > >>>> On 12/22/2010 at 03:04 PM, Victor Echavarry >>>> Diaz<[email protected]> wrote: >> We are trying to use ethtool to see the card speed and we receive >> the following message: >> >> ethtool eth0 Settings for eth0: No data available >> >> How we solve this? > > Upgrade to SLES11 SP1.
