Chapter 3 - Operation and Administration Using the CLI NPU Configuration
4Motion 122 System Manual
For example, run the following command to assign the IP address, 172.10.1.0,
and subnet mask, 255.255.255.0 to the external-management interface:
npu (config-if)# ip address 172.10.1.0 255.255.255.0
IMPORTANT
You can configure the IP address and subnet mask for only the external-management,
local-management, and bearer interfaces.
The bearer interface IP address is used also in other interfaces such as the ASN and CSN
interfaces. If you change the bearer interface IP address, you must save the configuration (run the
command npu# write) and reboot the NPU to apply changed IP address on ASN and CSN
interfaces.
IMPORTANT
An error may occur if:
 The IP address you have specified is already configured for another interface.
 You are trying to assign an IP address for an interface for which IP address configuration is not
permitted. This error is caused only for the internal-management interface (the pre-configured
IP address for this interface is 10.0.0.254).
