Junos Space 2.0 Release Notes
Network Activate Release 2.0 Issues
QoS Design
New Features
6
interface types (port, 802.1Q, and Q-in-Q). For example, a service normalized to 802.1Q
that specifies port, 802.1Q, and Q-in-Q UNI endpoints performs the necessary pop,
swap, or push operations to manipulate (inner and outer) VLAN tags to transport
single-tagged frames across the UNI endpoints.
Enhancements to Normalization option—Configure an Ethernet service with a specified
interface type to transport frames with a different tag height. For example, you can
create Layer 2 VPN Q-in-Q to Q-in-Q service that transports single-tagged frames or
a Layer 2 VPN 802.1Q to 802.1Q service that transports double-tagged frames.
The Network Activate 2.0 release includes the following known issues:
An AE interface that specifies one or more logical interfaces with assigned IP addresses
is not a candidate for UNI role assignment. [562759]
A Functional Audit might show incomplete information in the Functional Audit result
window. [559092]
Functional Audit might fail when you modify a service order by changing the role of an
N-PE device in a multihomed group from primary to secondary and then deploy the
service order, if the VPLS service definition specifies
"Asymmetric_Vlan_Range_Normalize_to_vlan_all" with Advanced option, and auto-pick
enabled. [565249]
The QoS Design application allows you to configure Quality of Service (QoS) features
to provide improved service to certain network traffic on Ethernet services. Enabling QoS
on an Ethernet service can improve network service by providing dedicated bandwidth,
setting traffic priorities across the network, improving loss characteristics, shaping network
traffic, and managing network congestion.
Create a QoS profile to configure classification and policing for UNI ingress traffic and
policing, scheduling and shaping for UNI egress traffic on Ethernet services. The QoS
Design application includes the following workspaces that allow you to define levels of
service that you can then apply to Ethernet services in the Network Activate application:
QoS Domains—Prestage QoS to partition your network into domains. A domain
represents a group of N-PE routers for which the QoS treatment on the uplink interfaces
is the same or similar. You can perform a single domain discovery operation to discover
all the QoS domains on your network. Each QoS domain includes only those N-PE
routers that share the exact rewrite rules and classifiers. If the scheduler maps are
different, they are grouped in the domain as separate scheduler maps.
Drop Profiles—Define parameters that allow packets to be dropped from the network.
Drop profiles define the meanings of the loss priorities. When the number of packets
queued is greater than the ability of the router to empty a queue, the queue requires a
method for determining which packets to drop from the network.
