[Solved] Networking Issue (Cant Ping the gateway)

Hi,

I installed AIX 7.1 on a blade though (hmc with vio). I can ping the IP address, but not the gateway. Is there anything that I should configure?

Is there anything that I have to check with vio setting or Am I missing any configuration?

Please let me know further.

Thank you

More than likely, you need to add a default route to the gateway in the routing table.

I already entered the gw and as per your suggestion I did below.

Code:
 route add default gw 192.48.226.1
0821-287 gw: bad value

That's a linux command; doesn't work that way in AIX.

Try:
Code:
chdev -l inet0 -a route=0,192.48.226.1

or smitty route

From the command line:

# route add -net default A.B.C.D

However, the chdev command above is better (smitty netstat) because these put it in the ODM and it is permanent.

However, if you cannot ping the gw, adding it will not help any.

1) can the VIOS ping the gw?
2) can you ping the VIOS?

if the answer to 1) is yes, and 2) is no you probably do not have the SEA setup yet.

if the answer to both is yes - I still suspect something wrong with the virtual ethernet setup.

Are there other partitons? Can they ping the gw? Can you ping the other partitions?

Yes the issue was resolved, it is an SEA and bridge issue.
