If you need to reconfigure an IP address of XenServer via the command line.

xe pif-reconfigure-ip uuid= mode=static IP= gateway= netmask=

If using DHCP for assigning IPs, then,

#xe pif-reconfigure-ip mode=dhcp uuid=

#xe pif-reconfigure-ip mode=static DNS= gateway=<IP of Gateway> IP= netmask= uuid=
