Parameter Description
■ Only one IP network interface can be configured with
OAMP in this table. To configure additional
management interfaces, see Configuring Additional
Management Interfaces.
'Ethernet Device'
underlying-dev
[InterfaceTable_
UnderlyingDevice]
Assigns an Ethernet Device to the IP interface. An
Ethernet Device is a VLAN associated with a physical
Ethernet port (Ethernet Group). To configure Ethernet
Devices, see Configuring Underlying Ethernet Devices.
By default, no value is defined.
Note: The parameter is mandatory.
IP Address
'Interface Mode'
mode
[InterfaceTable_InterfaceMode]
Defines the method that the interface uses to acquire its
IP address.
■ [3] IPv6 Manual Prefix = IPv6 manual prefix IP
address assignment. The IPv6 prefix (higher 64 bits)
is set manually while the interface ID (the lower 64
bits) is derived from the device's MAC address.
■ [4] IPv6 Manual = IPv6 manual IP address (128 bits)
assignment.
■ [10] IPv4 Manual = (Default) IPv4 manual IP address
(32 bits) assignment.
'IP Address'
ip-address
[InterfaceTable_IPAddress]
Defines the IPv4/IPv6 address in dotted-decimal
notation.
By default, no value is defined.
Note: The parameter is mandatory.
'Prefix Length'
prefix-length
[InterfaceTable_PrefixLength]
Defines the prefix length of the related IP address. This is
a Classless Inter-Domain Routing (CIDR)-style
representation of a dotted-decimal subnet notation. The
CIDR-style representation uses a suffix indicating the
number of bits which are set in the dotted-decimal format.
For example, 192.168.0.0/16 is synonymous with
192.168.0.0 and subnet 255.255.0.0. This CIDR lists the
number of ‘1’ bits in the subnet mask (i.e., replaces the
standard dotted-decimal representation of the subnet
mask for IPv4 interfaces). For example, a subnet mask of
255.0.0.0 is represented by a prefix length of 8 (i.e.,
11111111 00000000 00000000 00000000) and a subnet
mask of 255.255.255.252 is represented by a prefix length
of 30 (i.e., 11111111 11111111 11111111 11111100).
The prefix length is a Classless Inter-Domain Routing
(CIDR) style presentation of a dotted-decimal subnet
notation. The CIDR-style presentation is the latest
method for interpretation of IP addresses. Specifically,
instead of using eight-bit address blocks, it uses the
variable-length subnet masking technique to allow
allocation on arbitrary-length prefixes.
