4 x 25 Gbps Port Channelization
Before configuring a port for channelization, determine its associated used ports (see Table 8 on page 34 ).
In the following example, you’ll configure port et-0/0/4 to operate as a 4 x 25 Gbps channelized port.
1. Block the three ports following the desired channelized port as unused, and commit the configuration.
For example, because you are configuring et-0/0/4 as 4 x 25 Gbps, you must first configure the following
ports (et-0/0/5, et-0/0/6, and et-0/0/7) as unused and commit the configuration.
# set chassis fpc 0 pic 0 port 5 unused
# set chassis fpc 0 pic 0 port 6 unused
# set chassis fpc 0 pic 0 port 7 unused
# commit
Software removes these ports and updates the configuration.
2. Configure the speed on the desired port (et-0/0/4) as 25 Gbps, the number -of sub-ports as 4, and
commit the configuration:
# set chassis fpc 0 pic 0 port 4 speed 25g number-of-sub-ports 4
# commit
Delete 4 x 25 Gbps or 4 x 10 Gbps Port Channelization
To remove the channelization configuration from a set of QFX5220-128C ports, delete the configuration
from the channelized port and commit the configuration. For example:
# delete chassis fpc 0 pic 0 port port-number number-of-sub-ports 4
# delete chassis fpc 0 pic 0 port port-number speed port-speed
# commit
QFX5220-128C Network LEDs
The QSFP28 network ports use a single bi-colored LED for each port or channel to indicate link status,
activity on the link, or a fault condition. When the port is channelized, there is an LED for each channel;
when the port is not channelized, the left-most LED indicates the port link status.
