Re: why lano is different status between lancan and cmviewcl?

well, is there SUPPOSED to be physical connectivity between lan0 and lan1?
If so, you need to verify your cables, switch ports etc.

Re: why lano is different status between lancan and cmviewcl?

Try this for both - example:


# nwmgr -g -v -c lan22
lan2:
Interface State =DOWN
Probable Cause for State = Cable disconnect
MAC Address = 0x001A41234567
Subsystem = iether
Interface Type = 1000Base-T
Hardware Path = 0/3/1/0
NMID = 33
Feature Capabilities = Physical Interface
IPV4 Recv CKO
IPV4 Send CKO
VLAN Tag Offload
64Bit MIB Support
IPV4 TCP Segmentation Offload
UDP Multifrag CKO
Feature Settings = Physical Interface
VLAN Tag Offload
64Bit MIB Support
MTU = 1500
Speed = Autonegotiation : On
The link is down. Speed and other link state information are undefined.
Only the configured speed is shown.

Hope this helps!
Regards
Torsten.

Re: why lano is different status between lancan and cmviewcl?

Could be a bad card (port); bad cable or bad switch (port) - check them all. Of course you cannot check the cable from remote ... ;-)

Hope this helps!

Torsten.

Re: why lano is different status between lancan and cmviewcl?

Hi Torsten,
I think lan can should run well due to ioscan output show the status is claim,
as for switch port , how to know lan card connect to which switch port? thanks!
Torsten.

Re: why lano is different status between lancan and cmviewcl?

ioscan only says the card is alive, it says nothing about the ports of the NIC.

Consider to logon to the switch and check the ports. Normally the MAC will be shown, but without a connection you need to refer to your own documentation of cabling.

Hope this helps!
Regards
Torsten.

Re: why lano is different status between lancan and cmviewcl?

you will need to get your networking team to help here, as this could be a number of items. As Torsten says, the NIC card is ok, but a PORT on the card may be faulty, more likely a cable or networking device like a switch.
Get the switch checked out

Hi Torsten,
Thanks for you so nice support,
but I really do not know how to check the ports of NIC ?

Re: why lano is different status between lancan and cmviewcl?

Well, to check a port you must connect "something" there, even a cable (connect the other end "somewhere") or a loopback connector.

If you get "link up", cable and port are ok.

Hope this helps!

Torsten.
