Complementing the network configuration are some VLAN-related parameters, determining
if VLANs are enabled and the ‘Native’ VLAN ID (see the sub-sections below) as well as
VLAN priorities and DiffServ values for the supported Classes Of Service (see Quality of
Service Parameters on page 111).
10.3.1.1.2 Columns of the Multiple Interface Table
Each row of the table defines a logical IP interface with its own IP address, subnet mask
(represented by Prefix Length), VLAN ID (if VLANs are enabled), name, and application
types that are allowed on this interface. Multiple interfaces can be defined with a default
gateway. Traffic from this interface destined to a subnet which does not meet any of the
routing rules (either local or static routes) are forwarded to this gateway (as long this
application type is allowed on this interface). See 'Gateway Column' on page 109 for more
details.
10.3.1.1.2.1 IP Address and Prefix Length Columns
These columns allow the user to configure an IPv4 IP address and its related subnet mask.
The Prefix Length column holds the 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, in other
words, 192.168.0.0/16 is synonymous with 192.168.0.0 and a subnet 255.255.0.0 (Refer
to http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing for more information).
This CIDR notation lists the number of '1' bits in the subnet mask. So, a subnet mask of
255.0.0.0 (when broken down to its binary format) is represented by a prefix length of 8
(11111111 00000000 00000000 00000000), and a subnet mask of 255.255.255.252 is
represented by a prefix length of 30 (11111111 11111111 11111111 11111100).
