common naming convention, where JNP10K-LC1101 is the name used on the overlay for the LC1101 line
card. See Figure 49 on page 92.

Each QSFP28 socket supports:
•
100-Gigabit Ethernet using QSFP28 optical transceivers. When a QSFP28 transceiver is inserted into
any of the ports, the QSFP28 socket is enabled for 100-Gigabit Ethernet.
•
40-Gigabit Ethernet using QSFP+ optical transceivers. When a QSFP+ transceiver is inserted into any
of the ports, the QSFP+ socket is enabled for 40-Gigabit Ethernet.
Channelizing 40-Gigabit Ports
40-Gigabit Ethernet ports on the PTX10K-LC1101 line card can be channelized to 10-Gigabit Ethernet.
When ports are in channelization mode, the fourth port on each Packet Forwarding Engine is disabled,
and the remaining four ports that are mapped to the same Packet Forwarding Engine can be used as either
4x10 Gigabit Ethernet, 40-Gigabit Ethernet, or 100-Gigabit Ethernet ports. The channelization mode works
independently for each of the Packet Forwarding Engine on the PTX10K-LC1101 line card. See
Figure 50 on page 92 to see which ports are disabled and see Table 28 on page 92 for the maximum port
configurations.
