Database Administration Manual - IP7 Secure
Gateway
The IP address and subnet mask values cannot be changed to an address representing a different
network if:
If the network interface specified by the loc and port parameters has a default router, dnsa, or
dsnb parameter values assigned to it, as shown in the rtrv-ip-card output.
Any IP routes, shown in the rtrv-ip-rte output, reference the IP address for the network interface
specified by the loc and port parameters.
The IP link cannot be changed if open associations reference the IP link being changed.
The network portion of the IP addresses assigned to the IP links on an IP card must be unique. For
example, if IP links are assigned to IP card 1103, the network portion of the IP address for Ethernet
interface A (port=a) must be different from the IP address for Ethernet interface B (port=b).
The submask parameter value is based upon the ipadddr setting. See
