Run the following commands from a web console :
root@VRMSPR [ ~ ]# /opt/vmware/share/vami/vami_interfaces
eth0
eth1
eth2
By default eth0 is the management interface but you could have more out there depending on your requirements.
/opt/vmware/share/vami/vami_set_network <interface name> STATICV4 <IP Address> <NETMASK> <GATEWAY>
Example:
/opt/vmware/share/vami/vami_set_network eth0 STATICV4 192.168.10.11 255.255.255.0 192.168.0.1
/opt/vmware/share/vami/vami_set_dns -d <domain suffix> <DNS IP1> <DNS IP2>
You should be able to access the IP address now; a reboot will only be needed if its still not working.
