100-Gbps Port Configuration
All QSFP28 ports work by default as 100 Gbps. The ports are autosensing; if a 100 Gbps transceiver is
inserted, no configuration is required.
40-Gbps Port Configuration
Before configuring a port for 40 Gbps, determine its associated used port (see Table 8 on page 34 ). In the
following example, you’ll configure port et-0/0/0.
1. Block the port following the desired 40-Gbps port as unused and commit the configuration. For example,
because you are configuring et-0/0/0 as 40 Gbps, you must first configure the following port (et-0/0/1)
as unused and commit that configuration.
# set chassis fpc 0 pic 0 port 1 unused
# commit
2. Configure the speed on the desired port (et-0/0/0) as 40 Gbps and commit the configuration.
# set chassis fpc 0 pic 0 port 0 speed 40g
# commit
