Additional Features

We've extended support for the following features to the platforms shown in parentheses:

• CoS interface telemetry support (PTX10008). Support for gRPC Network Management Interface (gNMI) streaming of CoS interface queue statistics. To stream statistics, use the resource path /qos/interfaces/interface/output/queues/queue/state/.

  [See Guidelines for gRPC and gNMI Sensors (Junos Telemetry Interface).]

• On-box aggregation support (PTX10008)

  [See Junos YANG Data Model Explorer.]

• OpenConfig QoS operational state sensors (PTX10008)

  [See Telemetry Sensor Explorer.]

• IGMP snooping and MLD snooping (PTX10008 with the Express 5-based PTX10K-LC1301-36DD and Express 4-based PTX10K-LC1201-36CD and PTX10K-LC1202-36MR line cards). The device supports the features while operating in either of the following chassis modes:

  • (Default mode) Both Express 5 and Express 4 line cards interoperating on the device, called interop mode, where device operation is limited to the functions and scale of the Express 4 line card.

  • Only Express 5 line cards operating on the device. In this case, to enable the device to operate using the enhanced functions and scale available on the Express 5 line cards, enable the enhanced Express 5 mode on the device as follows:

    You must reboot the device for this setting to take effect.

  Note that Express 5 line cards don’t support multicast snooping route counters, which record the number of packets that use a snooping route toward the destination. However, Express 4 line cards do update the snooping route counters. As a result, on devices running in interop mode, the packet statistics reported in the show multicast snooping route extensive CLI command might not match the actual packet count for snooping routes.

  [See IGMP Snooping Overview and Understanding MLD Snooping.]

• Interoperability support for EVPN-VPWS service (PTX10008 with the Express 5-based PTX10K-LC1301-36DD and Express 4-based PTX10K-LC1201-36CD, PTX10K-LC1202-36MR line cards). The PTX10008 router supports the deployment of EVPN-VPWS on the PTX10K-LC1201-36C, PTX10K-LC1202-36MR, and PTX10K-LC1301-36DD line cards within the same chassis. The control word is automatically enabled and must remain enabled on all three line cards. We also do not recommend configuring a custom tag protocol identifier (TPID) on the PTX10K-LC1301-36DD line card because the PTX10K-LC1201-36C and PTX10K-LC1202-36MR line cards do not support custom TPID and the router might drop these packets.

  [See Overview of VPWS with EVPN Signaling Mechanisms.]

• Interconnecting EVPN-VXLAN data centers with EVPN-MPLS in WAN using gateway nodes (PTX10002-36QDD).

  [See Overview of EVPN-VXLAN Interconnect through EVPN-MPLS WAN Using Gateways.]

• OISM for IPv4 multicast traffic in EVPN-VXLAN fabrics (PTX10008 with the Express 5-based PTX10K-LC1301-36DD and Express 4-based PTX10K-LC1201-36CD and PTX10K-LC1202-36MR line cards). The device supports the feature while operating in either of the following chassis modes:

  • (Default mode) Both Express 5 and Express 4 line cards interoperating on the device, called interop mode, where device operation is limited to the functions and scale of the Express 4 line card.

  • Only Express 5 line cards operating on the device. In this case, to enable the device to operate using the enhanced functions and scale available on the Express 5 line cards, enable the enhanced Express 5 mode on the device as follows:

    You must reboot the device for this setting to take effect.

  Note that Express 5 line cards don’t support multicast snooping route counters, which record the number of packets that use a snooping route toward the destination. However, Express 4 line cards do update the snooping route counters. As a result, on devices running in interop mode, the packet statistics reported in the show multicast snooping route extensive CLI command might not match the actual packet count for snooping routes.

  In either mode, OISM support on this device includes:

  • Regular OISM mode only—The original symmetric bridge domains model, also called the bridge domains everywhere (BDE) model

  • MAC-VRF EVPN instances with vlan-based or vlan-aware service types only

  • IPv4 multicast traffic with IGMPv2, IGMPv3, and IGMP snooping

  • Server leaf, border leaf, or lean spine OISM device roles

  • External multicast source and receiver communication using any of the following methods:

    • Classic L3 interfaces

    • EVPN multicast VLAN (M-VLAN) integrated routing and bridging (IRB) interfaces

    • Non-EVPN IRB interfaces

  [See Optimized Intersubnet Multicast in EVPN Networks.]

• Support for multiple bridge domains and local switching in VPLS (PTX10002-36QDD). We support the following VPLS features:

  • Multiple bridge domains within a single VPLS routing instance

    [See Introduction to Configuring VPLS.]

  • Local switching with hierarchical VPLS

    [See Local Switching (VPLS) and Example: Configuring LDP-Based H-VPLS Using a Single Mesh Group to Terminate the Layer 2 Circuits.]

• Transport class tunnel support for EVPN (PTX10001-36MR, PTX10002-36QDD, PTX10004, PTX10008, and PTX10016). We support EVPN-VPWS, EVPN-ELAN, and EVPN E-Tree services over transport class tunnels on PTX Series devices. These devices use the unified next-hop hierarchy, which takes advantage of improvements in the RPD infrastructure to provide improved scalability and faster convergence performance. The PTX Series platform enables unified next-hop hierarchy by default.

  [See Configuring EVPN over Transport Class Tunnels.]

• Two-Way Active Measurement Protocol (TWAMP) monitoring service (RFC 5357) hardware timestamp support to enable Flex Algo and SR-MPLS support (ACX7020, ACX7024, ACX7100, ACX7332, ACX7348, ACX7509, PTX10001-36MR, PTX10002-36QDD, PTX10003, PTX10004, PTX10008, and PTX10016)

  [See the offload-type inline-timestamping option of the test-session statement.]

• MVPN bud node support with the looping back interface (LBI) (PTX10001-36MR, PTX10002-36QDD, PTX10004, PTX10008, and PTX10016).

  [See MVPN mLDP bud node support with Looping back interface.]

• Support for performance monitoring and TCA (PTX10008). Use performance monitoring for PTX10008 routers to measure current and historical metrics. The router accumulates these metrics into 15-minute and 1-day intervals. You can configure the 15-minute interval length. You can view these metrics by using the show interfaces transport pm command. This approach helps you manage optical transport links more efficiently.

• Firewall filter support (PTX10008)
