complete noob here coming from the cisco world. can an ex4550 with the 2 port 40g sfp insert use a 40g breakout cable (4x10g) in this system? if so how do i channelize this? i have read enough to realize i need to do this and can do it in cisco in seconds but need help with junos. any help would be appreciated.
Have you tried
If this solves your problem, please mark this post as "Accepted Solution."
the question i have is about the port number. in my system the 40g qsfp is et-0/1/1
what port number would i use? et-0/1/1:0 -3 or something else? cant seem to make this work
when i do this i get unsupported platform (ex4550-32t)
Thanks for the quick response.
Can you please find the below details, this might helps in EX series devices.
Channelize Block of Ports or Individual Port
You can either configure a port as a single interface (non channelized interface) or partition the port intosmaller data channels or multiple interfaces (channelized interfaces). On switches platform, you canchannelize an individual port or block of ports or quad ports based on the platform.
Interface Naming ConventionsEach interface name includes a unique identifier and follows a naming convention. When you configurethe interface, use the interface name. You can either configure a port as a single interface (non channelizedinterface) or partition the port into smaller data channels or multiple interfaces (channelized interfaces).When multiple interfaces are supported on a physical port, you use the colon (:) notation in the interfacenaming conventions as a delimiter to differentiate the multiple interfaces on a physical port. In the interfacenaming convention, xe-x/y/z:channel:
• x refers to the FPC slot number.• y refers to the PIC slot number.• z refers to the physical port number.• channel refers to the number of channelized interfaces.
When the 40-Gigabit Ethernetinterfaces (et-fpc/pic/port) are channelized as 10-Gigabit Ethernetinterfaces,the interface appears in the xe-fpc/pic/port:channel format, and channel is a value of 0 through 3.

so in my case would this be "set chassis fpc 0 pic 1 port 1:0 channel-speed 10g ?
the port i want to channelize is et-0/1/1
from the output you provided the platform is not supporting this configuration knob , i checked and found that Channelizing 40-Gigabit Ethernet QSFP+ interfaces is supported by the below list among which is not your switch model
the above link is feature explorer to know the supportability of both software and hardware to the features
Yes, this should be the general format for channelization but however, this is unsupported on the device that you are currently trying to run this on.
Hope this helps 🙂

Channelized interfaces enable you to configure a number of individual channels that subdivide the bandwidth of a larger interface and minimize the number of Physical Interface Cards (PICs) that an installation requires
Depending on the device and software package, 40-Gbps QSFP+ ports can be configured to operate as the following types of interfaces:
10-Gigabit Ethernet interfaces (xe)
40-Gigabit Ethernet interfaces (et and xle)
40-Gigabit data plane uplink interfaces (fte)
When an et port is channelized to four xe ports, a colon is used to signify the four separate channels. For example, on a QFX3500 standalone switch with port 2 on PIC 1 configured as four 10-Gigabit Ethernet ports, the interface names are xe-0/1/2:0, xe-0/1/2:1, xe-0/1/2:2, and xe-0/1/2:3
[edit chassis fpc slot-number pic pic-number]
To configure a PIC’s port speed:
1. Navigate to the [edit chassis] hierarchy level.2. Enter the port-speed statement at the [edit chassis fpc slot-number pic pic-number port port-number] hierarchy level.
[edit chassis]user@host# set fpc fpc-slot pic pic-number port port-number port-speed ;
3.Specify the port speed that needs to be configured. You can use one of the following speed attributes for this configuration.
[edit chassis]user@host# set fpc fpc-slot pic pic-number port port-number port speed 10G;user@host# set fpc fpc-slot pic pic-number port port-number port speed 40G;user@host# set fpc fpc-slot pic pic-number port port-number port speed 100G;
Configuring Rate Selectability
EX4550 does not support interface channelization.
These links provide a list of switches where channelizing 40g interfaces are supported.
