Hi all,
When I run ethtool against ethernet card, I get following output -
[root at datablade1 ~]# ethtool eth3
Settings for eth3:
Supported ports: [ FIBRE ]
Supported link modes: 1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 1000baseT/Full
Advertised auto-negotiation: Yes
Speed: Unknown!
Duplex: Unknown! (255)
Port: FIBRE
PHYAD: 2
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: g
* Link detected: no*
Note "Link detected: no"; what does it mean?
When I do ethtool -t eth3, I get following output -
[root at datablade1 ~]# ethtool -t eth3
*The test result is FAIL*
The test extra info:
register_test (offline) 0
memory_test (offline) 0
loopback_test (offline) 0
nvram_test (online) 0
interrupt_test (online) 0
link_test (online) 1
Note "*The test result is FAIL", *somehow I believe the above two outputs
are interlinked (the test result is FAIL because link detected is 'No').
How to fix this to make test result pass and link detected to 'Yes'? For
other ethernet card I can see the test result passing and link detected is
'Yes'
Thanks
