Re: Interface show claimed but it down on OS level.

Let us see what you have:

# nwmgr -S apa

# nwmgr -S apa -I 900 -v

# nwmgr -S apa -I 901 -v


Hope this helps!

Re: Interface show claimed but it down on OS level.

Looks like lan2 and lan3 are really down or have at least no link. This is the same dual ported card.

 

If you see something like this:

lan900   LAN_MONITOR LB_HS     1 Gbps Full Duplex   0,2*

the -> * <- mens there is a problem (lan2 in this case).

Check

# nwmgr -g -v -c lan2

and compare to let's say

# nwmgr -g -v -c lan0

 

However, both aggregates have a problem.

 

Active Port(s) = 0
   Ready Port(s) =  -
   Not Ready Port(s) = 2
   Connected Port(s) =  -

 

Check link status and port configuration at the switch side.


Hope this helps!

Torsten.
