Parameter Description
'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.
The valid value of the prefix length depends on the IP
address version:
■ IPv4: 0 to 30 (default is 16)
■ IPv6: 64 (default is 64)
'Default Gateway'
gateway
[InterfaceTable_Gateway]
Defines the IP address of the default gateway for the IP
interface. When traffic is sent from this interface to an
unknown destination (i.e., not in the same subnet and not
defined for any static routing rule), it is forwarded to this
default gateway.
By default, no value is defined.
DNS
'Primary DNS'
primary-dns
[InterfaceTable_
PrimaryDNSServerIPAddress]
Defines the primary DNS server's IP address (in dotted-
decimal notation), which is used for translating domain
names into IP addresses for the interface.
By default, no IP address is defined.
'Secondary DNS'
secondary-dns
[InterfaceTable_
SecondaryDNSServerIPAddress]
Defines the secondary DNS server's IP address (in
dotted-decimal notation), which is used for translating
domain names into IP addresses for the interface.
By default, no IP address is defined.
