Configuring Ports 25 to 37
Ports 25, 29, 33, and 37 support the following transceivers and cables:
40Gbps QSFP+ transceivers
100Gbps QSFP28 transceivers
40Gbps to 10Gbps copper and fiber optic breakout cables
You have to configure the ports for the transceivers with the PLATFORM
PORTMODE INTERFACE command in the Global Configuration mode.
The default setting for the ports is 40Gbps QSFP+ transceivers. You can
skip this procedure if you will be using only 40Gbps QSFP+ transceivers in
the ports.
Note
You have to reset the switch after configuring ports for 100Gbps
transceivers or after replacing 100Gbps transceivers with 40Gbps
transceivers or breakout cables.
To configure the ports, perform the following procedure:
1. Start a local management session. For instructions, refer to "Starting a
Local Management Session" on page 113.
2. Move to the Global Configuration mode by entering the ENABLE and
CONFIGURE TERMINAL commands. Refer to Figure 64 on page 117.
3. Enter the PLATFORM PORTMODE INTERFACE command to
configure the ports. The format of the command is shown here:
platform portmode interface ports 10gx4|40g|100g
The variables are defined here:
The PORTS variable specifies the ports to be configured. The port
variables are PORT1.0.25, PORT1.0.29, PORT1.0.33, and
PORT1.0.37. You can configure more than one port at a time.
The 10gx4 parameter configures ports for breakout cables.
The 40g parameter configures ports for 40Gbps QSFP+
transceivers. This is the default setting.
The 100g parameter configures ports for 100Gbps QSFP28
transceivers.
