Channelizing Interfaces on PTX10003 Routers with Junos OS Evolved
PTX10003 Packet Transport Routers feature flexible interface configuration options with universal multi-rate
double-density Quad Small Form-factor Pluggable (QSFP-DD) optics. The PTX10003-80C port panel has
40 physical ports and the PTX10003-160C port panel has 80 physical ports. The physical ports are in
groups of five QSFP-DD ports. You can configure different data rates for each port group as long as the
total throughput for the group does not exceed 1 Tbps. Any port can be used as a 100-Gigabit Ethernet
interface, 40-Gigabit Ethernet interface, or 10-Gigabit Ethernet interface. You choose the speed by plugging
in the appropriate transceiver.
NOTE: The center port in each port group (port 2 and port 7) cannot support 1x200 Gbps. To
configure a 200 Gbps data rate for those ports, you’ll need to configure them as 2x100 Gbps. For
more details, see “Understanding QSFP-DD Interfaces and Configurations” on page 28 .
You can channelize the Gigabit Ethernet interfaces on PTX10003 routers to create multiple independent
Gigabit Ethernet interfaces and then use breakout cables to connect the channelized ports to other servers,
storage devices, and routers. Here’s the allowable channelization configurations for the optical transceivers
supported by the PTX10003:
Channelization Options Native Port Speeds QSFP Transceiver
8x25 Gbps 1x200 Gbps
2x100 Gbps
QSFP28-DD
4x25 Gbps 1x100 Gbps QSFP28
4x10 Gbps 1x40 Gbps
4x10 Gbps
QSFP+
NOTE: For more details about supported transceivers and cable specifications, see the PTX10003
Packet Transport Router Hardware Guide .
By default, all PTX10003 QSFP-DD interfaces are configured for a data rate of 2x100 Gbps. The interface
names appear in the et-fpc/pic/port:channel format.
The port speed can be configured at the PIC-level. To view the port speed capability of a logical PIC, issue
the show chassis pic fpc-slot slot-number pic-slot slot-number command.
