  • 1.  Port matching between PTX1k devices

    Hi,

     

    I am new to JUNOS PTX1k, how do I get the port-speed matching between these 2 PTX1K ports:

    PTX1k-1   (et-0/0/37) -----------------------(port et-0/0/69) PTX1k-2

     

    It seems PTX1k-1 et-0/0/37 already has broken into 4 channelized 10G ports already (I don't have physical access to it at the moment) whereas PTX1k-2 et-0/0/69 has 40G port-speed configured, as seen  below.

    root@PTX1k-1> show interf terse
    et-0/0/37:0 up down
    et-0/0/37:1 up down
    et-0/0/37:2 up down
    et-0/0/37:3 up down

    Right now, PTX1k-2   et-0/0/69 is not even visible.


    root@ PTX1k-2> show interfaces et-0/0/69
    error: device et-0/0/69 not found

     

    Thanks,

    Hi, first of all check what is configured in chassis section. And verify with this doc

     

    By default, the network ports operate as channelized 4 x 10-Gigabit Ethernet interfaces

    Can I collapse these 4 channelized 10G to connect to another 40G port?

    Hey PL2,

     

    Yes, you can, as per documentation by default, the network ports operate as channelized 4 x 10-Gigabit Ethernet interfaces—using QSFP+ to SFP+ fiber breakout cables—for a maximum of 288 10-Gigabit Ethernet ports. You can configure each of the 72 ports as a 40-Gigabit Ethernet interface, in groups of three ports—when you configure the first port in a port group to operate at 40 Gbps, that port and the next two ports operate at 40 Gbps.

    From 'show chassis hardware', et-0/0/37 is 40G as seen below. How to make them compatible and connected?

     

    PTX1k-1   (et-0/0/37) -----------------------(port et-0/0/69) PTX1k-2

    PL2

     

    Try this configuration:

     

    PTX1k-1

    set chassis fpc 0 pic 0 port 36 speed 40g

     

    Please note that this command will configure these 3 ports to operate at 40GB

     

    36,37,38 

     

    PTX1k-2

     

    set chassis fpc 0 pic 0 port 69 speed 40g

     

    Please note that this command will configure these 3 ports to operate at 40GB

     

    69.70,71

     

    Do you want to know why it behaves like this ? is this expected?

     

    Yes, it is, All network ports on the PTX1000 can be configured as 40-Gigabit Ethernet interfaces. You must configure 40-Gigabit Ethernet interfaces in groups of three network ports. When the port speed is configured as 40 Gbps on the first port in a port group, all three ports in the port group operate at 40 GB.

    @LilDexx:

     

    It still didn't work, as I did per your instructions.  Port et-0/0/69 of PTX1k-2

    is still not found.

    Do you have 100gig enabled on port 71? it will disbale the port 69

    Thanks
