How to tell if NIC is running at 10 Base T or 100 Base T

[Debbie Fleith]

I know there is some command I could run to show the current stats of a NIC card. Anyone recall what that is?

We have experienced some network degredation and suspect our old HP server is possible the culprit.

lanadmin -x 0, where 0 is the PPA number, derived from lanscan.

[melvyn burnard]

you can use the lanadmin command to get this information.
man lanadmin

[Pete Randall · Accepted solution]

Sorry, lanscan refers to it as instance, not PPA number.

Hi Debbie:

With the old 100MB Base T cards, using auto-negotiation was virtually guaranteed to lead to problems at some time.

Configure your card to 100MB full duplex and set your network switch to the same.

Regards!

Hi,

run

# lanscan

to find all your LAN cards. In the output you'll find a column "CrdIn#". Use this value with lanadmin, e.g.

# lanadmin -x 0

and you will get this:

Current Speed = 100 Full-Duplex Auto-Negotiation-ON

Use the 'lanscan' command to get the ID of the NIC

Run the lanadmin command with the values obtained.

Example: '# lanadmin lan1'

You can also use the attached script...

1, Determine LAN ID by
# lanscan
Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI
Path Address In# State NamePPA ID Type Support Mjr#
0/0/0/0 0x00306E2C808B 0 UP lan0 snap0 1 ETHER Yes 119
0/2/0/0 0x00306E370901 1 UP lan1 snap1 2 ETHER Yes 119
2, Then
# lanadmin lan1

Just do a lanscan, find the NM ID and run
lanadmin -s NM ID

root@myserver>/dp # lanscan

root@myserver>/dp # lanadmin -s 1
Speed = 100000000

root@myserver>/dp # lanadmin -s 2
Speed = 10000000
