•
Junos Trio chipsets for increased scaling for bandwidth,
subscribers, and services
•
Twelve Gigabit Ethernet ports that can be configured
as 40-Gigabit Ethernet port or as 4X10-Gigabit Ethernet
port using a breakout cable. The ports support quad
small-form factor pluggable plus (QSFP+) transceivers.
•
Four out of the twelve ports can be configured as
100-Gigabit Ethernet ports. Port numbers 0/2, 0/5, 1/2
and 1/5 are the four 100-Gigabit Ethernet ports.
•
You can configure different combination of port speeds
as long as the aggregate capacity per group of six ports
labeled 0/0 through 0/5 does not exceed 240 Gbps.
Similarly, aggregate capacity per group of the other six
ports labeled 1/0 through 1/5 should not exceed
240 Gbps.
•
Requires high-capacity power supplies and high-capacity
fan trays.
•
The ports are labeled as (see Figure 65 on page 143 ):
•
10-Gigabit Ethernet or 40-Gigabit Ethernet ports:
0/0, 0/1, 0/2 100G, 0/3, 0/4, 0/5 100G, 1/0, 1/1,
1/2 100G, 1/3, 1/4, and 1/5 100G
•
100-Gigabit Ethernet ports:
0/2 100G, 0/5 100G, 1/2 100G and 1/5 100G
NOTE: Only ports marked 100G support 100-Gigabit
Ethernet speed using QSFP28 transceivers.
