• Policy ID
ID for the policy. This is auto generated and shall be used when selecting the
polices that shall be mapped to the specific ports.
• Application Type
Intended use of the application types:
Voice - for use by dedicated IP Telephony handsets and other similar appliances
supporting interactive voice services. These devices are typically deployed on a
separate VLAN for ease of deployment and enhanced security by isolation from
data applications.
Voice Signaling (conditional) - for use in network topologies that require a
different policy for the voice signaling than for the voice media. This application
type should not be advertised if all the same network policies apply as those
advertised in the Voice application policy.
Guest Voice - support a separate 'limited feature-set' voice service for guest
users and visitors with their own IP Telephony handsets and other similar
appliances supporting interactive voice services.
Guest Voice Signaling (conditional) - for use in network topologies that require
a different policy for the guest voice signaling than for the guest voice media. This
application type should not be advertised if all the same network policies apply as
those advertised in the Guest Voice application policy.
Softphone Voice - for use by softphone applications on typical data centric
devices, such as PCs or laptops. This class of endpoints frequently does not
support multiple VLANs, if at all, and are typically configured to use an 'untagged’
VLAN or a single 'tagged’ data specific VLAN. When a network policy is defined
for use with an 'untagged’ VLAN (see Tagged flag below), then the L2 priority field
is ignored and only the DSCP value has relevance.
Video Conferencing
Streaming Video - for use by broadcast or multicast based video content
distribution and other similar applications supporting streaming video services
that require specific network policy treatment. Video applications relying on TCP
with buffering would not be an intended use of this application type.
Video Signaling (conditional) - for use in network topologies that require a
separate policy for the video signaling than for the video media. This application
type should not be advertised if all the same network policies apply as those
advertised in the Video Conferencing application policy.
• Tag
Tag indicating whether the specified application type is using a 'tagged’ or an
'untagged’ VLAN.
Untagged indicates that the device is using an untagged frame format and as
such does not include a tag header as defined by IEEE 802.1Q-2003. In this case,
both the VLAN ID and the Layer 2 priority fields are ignored and only the DSCP
value has relevance.
Tagged indicates that the device is using the IEEE 802.1Q tagged frame format,
and that both the VLAN ID and the Layer 2 priority values are being used, as well
as the DSCP value. The tagged format includes an additional field, known as the
tag header. The tagged frame format also includes priority tagged frames as
defined by IEEE 802.1Q-2003.
• VLAN ID
VLAN identifier (VID) for the port as defined in IEEE 802.1Q-2003
• L2 Priority L2 Priority is the Layer 2 priority to be used for the specified application type. L2
Priority may specify one of eight priority levels (0 through 7), as defined by IEEE
802.1D-2004. A value of 0 represents use of the default priority as defined in IEEE
802.1D-2004.
• DSCP
DSCP value to be used to provide Diffserv node behavior for the specified
application type as defined in IETF RFC 2474. DSCP may contain one of 64 code
point values (0 through 63). A value of 0 represents use of the default DSCP value
as defined in RFC 2475.
Port Policies Configuration
Every port may advertise a unique set of network policies or different attributes for the same network policies, based on the
authenticated user identity or port configuration.
