NATIVE IP COMMANDS
Using the native-ip dhcp pre-auth-mode command
The system should enable upon configuration to pre-authenticate a Native IP session, which uses DHCP (DHCP
discover) for IP allocation based on its MAC address. A successful pre-authentication will forward the DHCP
discover message to the DHCP server.
This command defines the system pre-authentication method in a DHCP request for native IP tunnels. The system
default pre-authentication value is none. When the system native-ip dhcp pre-auth-mode is configured to none it
should not appear via the write terminal command.
Usage
native-ip dhcp pre-auth-mode <mode> <none | MAC | reject-MAC>
Parameter(s)
<mode>
Pre authentication mode. Valid values are: none, MAC, or reject-MAC:
•none–No pre-authentication mode.
•MAC–Auth by MAC (on auth-reject, grant default service).
•reject-MAC–Auth by MAC (on auth-accept, grant default service).
Example(s):
Using native-ip def-service-auth command
The native-ip def-service-auth command instructs that the default native IP service be granted to the connected
native IP sessions. It defines the system default native-ip service name.
The default native IP service name is "GNativeIP". When configured to its default value, the write terminal
command does not present the command line.
Usage
native-ip def-service-auth [<service name>]
Parameter(s)
<service name>
Default native IP service name. Alpha-numeric string of up to 32 characters.
