Solution  1020018.1 :   Confirm network settings are correct  


PreviouslyPublishedAs
250928

Description
This document would explain the details of required steps to confirm network settings are correct

Steps to Follow
We will provide an overview of confirming correct network settings in LDOM
***NOTE*** Configuration changes to LDoms need to be saved to the SP using the
ldm(1M) add-config subcommand. If not, the configurations will be lost when the
primary domain is rebooted.

We are using one control domain and two guest domains in the below configuration
# /opt/SUNWldm/bin/ldm ls

1.  ping test ( non hybrid )
     a) from guest domain to control domain/primary domain
        ldom01> ping 10.5.60.232
                10.5.58.211 is alive
       
     b) from one guest domain(ldom01) to another guest domain(ldom02) which are on the same subnet
        ldom01> ping 10.5.63.113
                10.5.63.113 is alive
   
     c) from guest domain to external machine IP address
        ldom01># ping  10.5.58.211
