Hardware
- CFP-GEN2-CGE-ER4 and CFP-GEN2-100GBASE-LR4 (PTX5000)—The CFP-GEN2-CGE-ER4 transceiver (part number: 740-049763)
provides a duplex LC connector and supports the 100GBASE-ER4 optical
interface specification and monitoring. The CFP-GEN2-100GBASE-LR4
transceiver (part number: 740-047682) provides a duplex LC connector
and supports the 100GBASE-LR4 optical interface specification and
monitoring. Starting in Junos OS Release 13.3, the “GEN2”
optics have been redesigned with newer versions of internal components
for reduced power consumption. The following interface module supports
the CFP-GEN2-CGE-ER4 and CFP-GEN2-100GBASE-LR4 transceivers. For more
information about interface modules, see the Interface Module
Reference for your router.
- 100-Gigabit Ethernet PIC with CFP (model number: P1-PTX-2-100GE-CFP)—Supported in Junos OS Release 12.3R5, 13.2R3, 13.3R1, and later
[See 100-Gigabit Ethernet 100GBASE-R Optical Interface Specifications.]
- Support for three-phase delta AC power distribution
unit (PDU), three-phase wye AC PDU, and the AC power supply module
(PSM) on the PTX5000—The PTX5000 now supports
the three-phase delta AC PDU, three-phase wye AC PDU, and the AC PSM.
You can use the show chassis hardware, show chassis hardware-models, and show environment pdu commands
to view these hardware components.
Note: Mixing the DC and AC power components on the same chassis is not supported.
- Support for new 60 A DC power distribution
unit (PDU) and 60 A DC power supply module (PSM) on the PTX5000 Packet
Transport Router—Each 60 A PDU has four dual-input
input power trays. Each DC power cable, which you must provide, requires
a 4-AWG cable lug minimum.
Note: Mixing the 60 A DC PDU and 120 A DC PDU is not supported except during upgrade. The 60 A DC PSM is supported only in the 60 A DC PDU.
- SFPP-10GE-ZR
transceiver—The PTX5000 supports the SFPP-10GE-ZR
transceiver on the 10-Gigabit Ethernet PIC with SFP+ (model number:
P1-PTX-24-10GE-SFPP). The SFPP-10GE-ZR transceiver supports the 10GBASE-Z
optical interface standard. For more information, see the “Cables
and Connectors” section in the PIC guide.
[See 10-Gigabit Ethernet 10GBASE Optical Interface Specifications and the PTX Series Interface Module Reference.]
- CFP-100GBASE-ER4
and CFP-100GBASE-SR10 transceivers—The PTX5000
supports the CFP-100GBASE-ER4 and CFP-100GBASE-SR10 transceivers on
the 100-Gigabit Ethernet PIC with CFP (model number: P1-PTX-2-100GE-CFP).
The CFP-100GBASE-ER4 transceiver supports the 100GBASE-ER4 optical
interface standard. The CFP-100GBASE-SR10 transceiver supports the
100GBASE-SR10 optical interface standard. For more information, see
the “Cables and connectors” section in the PIC guide.
[See 100-Gigabit Ethernet 100GBASE-R Optical Interface Specifications and PTX Series Interface Module Reference.]
- SFPP-10G-ZR-OTN-XT
(PTX Series)—The SFPP-10G-ZR-OTN-XT dual-rate
extended temperature transceiver provides a duplex LC connector and
supports the 10GBASE-Z optical interface specification and monitoring.
The transceiver is not specified as part of the 10-Gigabit Ethernet
standard and is instead built according to ITU-T and Juniper Networks
specifications. The following interface modules support the SFPP-10G-ZR-OTN-XT
transceiver:
PTX Series:
- 10-Gigabit Ethernet PIC with SFP+ (model number: P1-PTX-24-10GE-SFPP)—Supported in Junos OS Release 12.3R5, 13.2R3, 13.3, and later
- 10-Gigabit Ethernet LAN/WAN OTN PIC with SFP+ (model number: P1-PTX-24-10G-W-SFPP)—Supported in Junos OS Release 12.3R5, 13.2R3, 13.3, and later
For more information about interface modules, see the “Cables and Connectors” section in the Interface Module Reference for your router.
[See 10-Gigabit Ethernet 10GBASE Optical Interface Specifications.]
Firewall Filters
- DSCP and Traffic Class firewall filter match
conditions on the loopback interface—You can set
the DSCP value for IPv4 traffic and Traffic Class value for IPv6 traffic
in firewall filters that you apply to the loopback (lo.0) interface. To configure these forwarding class and DSCP values,
apply an output filter to the lo.0 interface.
[See Standard Firewall Filter Match Conditions for IPv4 Traffic and Standard Firewall Filter Match Conditions for IPv6 Traffic.]
Interfaces and Chassis
- Aggregated devices
support increased to 64 links (PTX Series)—This
feature adds support for specifying up to 64 links for aggregated
Ethernet devices. You set the number of links in the maximum-links statement at the [edit chassis aggregated-devices] hierarchy
level.
[See Configuring Junos OS for Supporting Aggregated Devices.]
- WAN PHY support
for the PTX Series —You can configure WAN PHY
mode on 10-Gigabit Ethernet interfaces on PTX Series Packet Transport
Routers. Only the 24-port 10-Gigabit Ethernet LAN/WAN PIC with SFP+
(model number: P1-PTX-24-10G-W-SFPP) supports WAN PHY mode. To configure
WAH PHY mode, include the framing wan-phy statement at
the [edit interfaces xe-fpc/pic/port] hierarchy level. The default framing
mode for 10-Gigabit Ethernet interfaces is LAN PHY.
[See PTX Series Packet Transport Switches Software Documentation.]
- SFPP-10G-CT50-ZR (PTX Series)—The
SPFF-10G-CT50-ZR tunable transceiver provides a duplex LC connector
and supports the 10GBASE-Z optical interface specification and monitoring.
The transceiver is not specified as part of the 10-Gigabit Ethernet
standard and is instead built according to Juniper Networks specifications.
Only WAN-PHY and LAN-PHY modes are supported. To configure the wavelength
on the transceiver, use the wavelength statement at the [edit interfaces interface-name optics-options] hierarchy level. The following interface module supports the SPFF-10G-CT50-ZR
transceiver:
PTX Series:
- 10-Gigabit Ethernet LAN/WAN OTN PIC with SFP+ (model number: P1-PTX-24-10G-W-SFPP)—Supported in Junos OS Release 13.2R3, 13.3R2, 14.1, and later
For more information about interface modules, see the “Cables and Connectors” section in the Interface Module Reference for your router.
[See 10-Gigabit Ethernet 10GBASE Optical Interface Specifications and wavelength.]
Network Management and Monitoring
- Real-time performance monitoring (RPM) support
on PTX Series Packet Transport Routers—Real-time
performance monitoring (RPM) allows the user to perform service-level
monitoring. When RPM is configured on a device, the device calculates
network performance based on packet response time, jitter, and packet
loss. You can configure these values to be gathered by the following
types of requests: Hypertext Transfer Protocol (HTTP) GET, Internet
Control Message Protocol (ICMP), TCP, or UDP. The device gathers RPM
statistics by sending out probes to a specified probe target, identified
by an IP address or URL. When the target receives a probe, it generates
responses that are received by the device. You set the probe options
in the probe statement at the [edit services rpm] hierarchy level. You set the server to receive the probes in the probe-server statement at the [edit services rpm] hierarchy level. You use the show services rpm probe-results and show services rpm history-results commands to view
the results of the most recent RPM probes.
Note: The PTX5000 supports up to 200 concurrent RPM sessions.
The following statements at the [edit services rpm] hierarchy are not supported:
- twamp
- bgp logical-system
- probe owner test name destination-interface
- probe owner test name hardware-timestamp
- probe owner test name one-way-hardware-timestamp
- probe-server icmp
- probe-server tcp destination-interface
- probe-server udp destination-interface
User Interface and Configuration
- Features from Junos OS 12.1X48 are now integrated
in Junos OS Release 12.3 (PTX Series)— All features
supported in the Junos OS Release 12.1X48 release are supported in
