MX10008 Line Card (MX10K-LC2101)
MX10008 has eight horizontal line card slots and supports line rate for each line card. The line cards
combine a Packet Forwarding Engine and Ethernet interfaces enclosed in a single assembly. The MX10008
line card architecture is based on a number of identical, independent Packet Forwarding Engine slices each
with 400 Gbps full-duplex throughput. Line cards are FRUs that can be installed in the line card slots
labeled 0 through 7 (top to bottom) on the front of the chassis. All line cards are hot-removable and
hot-insertable. After the hot insertion, the line card comes online automatically.
The MX10K-LC2101 line card is available for the MX10008. The MX10K-LC2101 line card can support
24 100-Gigabit Ethernet ports with a 28-Gbps quad smallform-factor pluggable (QSFP28) transceiver, or
24 40-Gigabit Ethernet ports with a QSFP transceiver. The MX10K-LC2101 line cards also support
10-Gigabit Ethernet interfaces. For 10-Gigabit Ethernet, you must configure the port using the channelization
command. Because there is no port-groups option for the 100-Gigabit Ethernet line card, you must use
individual port channelization commands.
Figure 5 on page 26 shows the MX10K-LC2101 line card.
