Each QSFP28 socket can be configured to support:
100-Gigabit Ethernet using QSFP28 optical transceivers. When a QSFP28 transceiver is inserted into
the ports marked with a fine black line underneath the socket and the port is configured for 100-Gigabit
Ethernet, the two adjacent ports are disabled and the QSFP28 socket is enabled for 100-Gigabit Ethernet.
40-Gigabit Ethernet using QSFP+ optical transceivers.
10-Gigabit Ethernet using breakout cabling and attached optical transceivers. When configured for
channelization, the system converts the 40-Gigabit Ethernet port into 4 independent 10-Gigabit Ethernet
ports.
Network Ports
Each of the 12 QSFP28 ports supports:
100-Gigabit Ethernet QSFP28 transceivers
40-Gigabit Ethernet QSFP+ transceivers
Each of the 36 QSFP+ ports supports:
40-Gigabit Ethernet QSFP+ transceivers
Every second and sixth port in a 6XQSFP cage on a LC1102 supports 100-Gigabit Ethernet using QSFP28
transceivers. These 100-Gigabit Ethernet ports work either as 100-Gigabit Ethernet or as
40-Gigabit Ethernet, but are recognized as channelized 4x10-Gigabit Ethernet by default. See
Figure 52 on page 96 for a closeup view of a 6XQSFP+ cage. When a 40-Gigabit Ethernet transceiver is
inserted into a 100-Gigabit Ethernet port, the port recognizes the 40-Gigabit Ethernet port speed. When
a 100-Gigabit Ethernet transceiver is inserted into the port and enabled in the CLI, the port recognizes
the 100-Gigabit Ethernet speed and disables two adjacent 40-Gigabit Ethernet ports. See
Figure 53 on page 96 and
and run it at 40-Gigabit Ethernet by using the CLI to set the port speed to 40-Gigabit Ethernet.
Figure 52 on page 96 shows the location of QSFP+ ports for the PTX10K-LC1102.
