| Hardware features | * Line-rate throughput of up to 480 Gbps on MX240, MX480, and MX960
routers.
 * Line-rate throughput of up to 400 Gbps on MX2000 routers with
SFB, and up to 430 Gbps on MX2000 routers with SFB2.
 
 * 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 four 10-Gigabit Ethernet ports using
a
 breakout cable. The ports support quad small-form factor pluggable
plus (QSFP+) transceivers. The 40Gbps or 100Gbps ports
 configured to run at 10Gbps speed are shown in the CLI as follows:
 show interfaces terse Interface Admin Link Proto Local Remote
xe-10/0/0:0 up down xe-10/0/0:1 up down xe-10/0/0:2 up down
xe-10/0/0:3 up down
 
 * 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, high-capacity fan trays,
and SCBE2 or SCBE3 switch control boards on MX240, MX480, and
 MX960 routers.
 
 * Requires an adapter card to be housed in MX2000 routers.
 
 * The ports are labeled as (with the MPC orientation as shown in
the above figure):
 * 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.
 
 
 
 
 * Supports maximum transmission units (MTUs) from 256 bytes through
16,000 bytes for transit traffic, and from 256 bytes through
 9,500 bytes for host bound packets.
 
 
 NOTE: On MX960 routers, all the MPC slots can be occupied by MPC7E
MRATE line cards at an ambient temperature of up to 40° C and
 at any altitude. All the MPC slots can be occupied by an MPC7E
MRATE line card at temperatures of up to 55° C and at sea level. At
 an ambient temperature of above 55° C, and at an altitude above sea
level, slot 11 cannot host MPC7E MRATE line cards.
