Syntax
ip address
ip-address { mask | mask-length } [ sub ]
undo ip address [ ip-address { mask | mask-length } [ sub ] ]
View
VLAN interface view, loopback interface
view
Parameters
ip-address:
IP address, in dotted decimal notation.
mask: Subnet mask, in dotted decimal notation.
mask-length:
Subnet mask length, the number of consecutive ones in the mask. It is in the
range of 0 to 32.
sub: Specifies
a secondary IP address of a VLAN or loopback interface.
Description
Use the ip address command to
specify an IP address and mask for a VLAN or loopback interface.
Use the undo ip address command to
remove an IP address and mask of a VLAN or loopback interface.
By default, no IP address is configured for
VLAN or loopback interface.
Note that:
l
If you execute the undo ip address
command without any parameter, the switch deletes both primary and secondary IP
addresses of the interface.
l
The undo ip address ip-address { mask
| mask-length } command is
used to delete the primary IP address.
l
The undo ip address ip-address { mask
| mask-length } sub
command is used to delete specified secondary IP addresses.
l
You can assign at most five IP address to an interface,
among which one is the primary IP address and the others are secondary IP
addresses. A newly specified primary IP address overwrites the previous one if
there is any.
l
The primary and secondary IP addresses of an
interface cannot reside on the same network segment; the IP address of a VLAN
interface must not be in the same network segment as that of a loopback
interface on a device.
l
A VLAN interface cannot be configured with a
secondary IP address if the interface has been configured to obtain an IP
address through BOOTP or DHCP.
Related commands: display ip interface.
Examples
# Assign the primary IP address 129.12.0.1 and
secondary IP address 129.12.1.1 to VLAN-interface 1 with subnet mask

Parameters
ip-address1, ip-address2: Destination IP addresses, in dotted decimal notation. ip-address1
and ip-address2 together define an address range. The FIB entries in
this address range will be displayed.
mask1, mask2:
Subnet masks, in dotted decimal notation.
mask-length1, mask-length2: Length of the subnet masks, the number of consecutive ones in the
masks, in the range of 0 to 32.
longer:
Displays the FIB entries matching the specified address/mask and having masks
longer than or equal to the specified mask. If no masks are specified, FIB
entries that match the natural network address and have the masks longer than
or equal to the natural mask will be displayed.
Description
Use the display fib ip-address
command to view the FIB entries matching the specified destination IP address.
If no mask or mask length is specified, the
FIB entry that matches the destination IP address and has the longest mask will
be displayed; if the mask is specified, the FIB entry that exactly matches the
specified destination IP address and mask will be displayed.
