Chapter 1  IP Address Configuration Commands

1.1  IP Address Configuration Commands

1.1.1  ip address

Syntax

ip address ip-address net-mask [ sub ]

undo ip address [ ip-address net-mask [ sub ] ]

View

Interface view

Parameter

ip-address: Interface IP address, in dot delimitated decimal format.

net-mask: The mask of the corresponding subnet in dot delimitated decimal format, or the mask length to be specified.

sub: To enable communications among different subnets, the configured slave IP address should be used.

Description

Use the ip address command to set an IP address for an interface.

Use the undo ip address command to delete an IP address of the interface.

By default, no IP address for an interface is configured.

Users can select proper IP subnet according to actual conditions. Moreover, in the case that part of the host address is composed of 0 or the entire host address is composed of 1, the address has some special use and can not be used as ordinary IP address.

The mask identifies the network number in an IP address.

Under normal conditions, one interface only needs to be configured with one IP address. However, to enable one interface of a router to connect to several subnets, one interface can be configured with several IP addresses. Among them, one is master IP address, and others are slave IP addresses. Following is the relationship between the master and slave IP addresses:

l           If a master IP address is configured while there’s already an existing master IP address, the original one will be deleted and the newly configured will take effect.

l           The command undo ip address without parameters indicates to delete all the IP addresses of the interface. The command undo ip address ip-address net-mask indicates to delete the master IP address and undo ip address ip-address net-mask sub indicates to delete the slave address. All the slave addresses must be deleted before the master IP address can be deleted.

In addition, any two IP addresses configured for all interfaces on a router cannot be located in the same subnet.

Related command: ip route-static, display ip interface, and display interface.

Example

# Configure the interface Serial 0/0/0 with the master IP address as 129.102.0.1, the slave IP address is 202.38.160.1, and the subnet mask of both is 255.255.255.0.

[H3C-Serial0/0/0] ip address 129.102.0.1 255.255.255.0

[H3C-Serial0/0/0] ip address 202.38.160.1 255.255.255.0 sub

1.1.2  ip address ppp-negotiate

Syntax

ip address ppp-negotiate

undo ip address ppp-negotiate

View

Interface view

Parameter

None

Description

Use the ip address ppp-negotiate command to allow IP address be assigned through negotiation at the interface.

Use the undo ip address ppp-negotiate command to disable this function.

By default, no interface IP address negotiation is allowed.

As PPP supports IP address negotiation, only when the interface is encapsulated with the link-layer protocol PPP, can the IP address negotiation at this interface be configured.

Normally, it is not necessary to configure IP address negotiation. Only i
