New features – S9500-30XS platform

New CLI commands associated with the new features can be found in the configuration section.

QoS - support on LAG interfaces

This feature provides support for Quality of Service (QoS) on LAG interfaces (bonding interfaces).

QoS - queue depth and WRED thresholds configuration enhancements

This feature improves the configuration of queue size and WRED thresholds, allowing them to be specified in units of time.

Previously, the Queue depth and WRED thresholds could only be configured in units of packets on a software platform (Vyatta NOS, VNF platform) or bytes on the S9500-30XS platform. This feature will allow for the queue size and WRED thresholds to be specified in units of time (milliseconds or microseconds).

L3 egress ACL support for IP_DSCP and IPv6 hop limit

This feature extends the existing simple stateless IP packet filters (L3 ACLs) support to include the ability to match these additional fields.

QoS – enhanced DSCP remarking support

This feature gives packet remarking support which is essential to provide a deterministic end-to-end QoS for a traffic stream.

This feature adds the ability to support remarking of the DSCP values in the transmitted routed traffic according to the egress mapping and is added to help support multicast use-case where the traffic source is un-trusted.

The ability to classify and mark/remark the packets based on the L2 and L3 QoS fields such as Dot1p and DSCP are essential to provide a deterministic end-to-end QoS for a traffic stream. Vyatta NOS currently has support to classify the incoming packets on both Dot1p and DSCP and map it to the corresponding queues, but on the egress direction support exists only to remark the Dot1p bits of the packet from the DSCP or internal priority, whereas there is no support to remark the DSCP value in the transmitted packet.

MPLS L3VPN labeled unicast and 6PE support in hardware forwarding

This feature adds MPLS support on the S9500-30XS platform.

Previously, MPLS L3VPNs were only supported in the control plane and software forwarding path, but not in any hardware forwarding platforms. This feature adds support for MPLS Layer-3 Virtual Private Networks (L3VPNs) on the S9500-30XS platform.

PTP support for phase and time synchronization

IEEE-1588 Precision Time Protocol (PTP) support adds phase and time synchronization in the G.8275.1 telecom profile.

This feature adds support for this telecom profile, which is defined by ITU-T G.8275.1 and intended to be used by telecom applications requiring accurate phase and time synchronization. ITU-T G.8275.2 is based on the 1588v2 default profile, and supports the specific architecture described in ITU-T G.8275 allowing the distribution of phase/time from the network.

Backplane visibility support on hardware based platforms

This feature provides the ability to view operational statistics on backplane interfaces.

On hardware platforms with switching SoCs, a backplane of some form (for example, PCIe or -KR) exists between the CPU and the SoC. These backplane interfaces are used for any traffic to and from the CPU referred to as FORUS/FROMUS traffic. This feature adds support for operational statistics on these backplane interfaces, providing visibility into the L1 operational state, RX/TX load and error counters.
