Version 6.2 81 February 2011
SIP User's Manual 3. Web-Based Management
Parameter Description
[5] Media + Control = Only Media and Call Control
applications are allowed on the interface.
[6] OAMP + Media + Control = All application types are
allowed on the interface.
Notes:
A single OAMP interface (and only one) must be
configured. This OAMP interface can be combined with
Media and Control interfaces.
At least one interface for Media traffic and at least one
interface for Control traffic must be configured. These
interfaces can be combined (i.e., Media + Control, or
OAMP + Media + Control).
Multiple interfaces for Media, Control, and Media and
Control can be configured.
At least one IPv4 interface with Control must be configured.
This can be combined with OAMP and Media.
At least one IPv4 interface with Media must be configured.
This can be combined with OAMP and Control.
Web/EMS: IP Address
[InterfaceTable_IPAddres]
The IPv4 IP address in dotted-decimal notation.
Notes:
Each interface must be assigned a unique IP address.
When booting using BootP/DHCP protocols, an IP address
is obtained from the server. This address is used as the
OAMP address for the initial session, overriding the
address configured using the InterfaceTable. The address
configured for OAMP applications in this table becomes
available when booting from flash again. This enables the
device to operate with a temporary address for initial
management and configuration while retaining the address
to be used for deployment.
Web/EMS: Prefix Length
[InterfaceTable_PrefixLength]
Defines 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 (e.g. 192.168.0.0/16
is synonymous with 192.168.0.0 and a subnet of 255.255.0.0.
Defines 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 (refer to
http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing
for more information).
For IPv4 Interfaces, the prefix length values range from 0 to
31.
Note: Subnets of different interfaces must not overlap in any
