EX4650 - gigabit interface configuration?

  • 1.  EX4650 - gigabit interface configuration?

    Posted 03-22-2020 02:40

    I am trying to configure a brand new EX4650, running 18.4R2-S3. Right now I have a number of SFP+ (10Gbps) modules plugged into it, and they're all working fine and passing traffic. However, when I plug in an SFP (1Gbps) module, I can see it in the chassis hardware (as 'SFP-LX10), but it does not appear in the list of interfaces - 'show interfaces terse' skips that port number. Is there some option that I need to set to enable 1Gbps support?

    Hi Boris

    Could you paste the output of show chassis hardware and show interface terse ?

    Found it. Needed to issue the following:

    set chassis fpc 1 pic 0 port 44 speed 1G (or 25g)

     

    Note that it changes the speed for ports in groups of 4, i.e. setting port 44 to 1G changes this setting for ports 44, 45, 46 and 47.

    @Boris - this is spelled out at - https://www.juniper.net/documentation/en_US/junos/topics/topic-map/switches-interface-port.html

     

    You might have been looking here, which does not what is needed as clear as above.

     

    https://www.juniper.net/documentation/en_US/release-independent/junos/topics/topic-map/ex4650-hardware-overview.html

     

    Per NOTE under EX4650 Switch First View

     

    The SFP28 speed can be applied only for individual quads (four ports). The speed cannot be configured for a single port.

     

    BIG Question: You are setting with fpc 1, not fpc 0, is this EX4650 maybe set as a VC with another EX4650?  If yes, what SW release are you running?

     

    Thanks

    Yes, it is a member of a virtual chassis. Running version 18.4R2-S3.

    Hello,

     

    I don't have an EX4650 available to check, but you can try the following command:

     

    set chassis fpc <slot-number> port <port-number> channel-speed 1g

    Sorry, the only option available to me under that section is 'disable-auto-speed-detection'.

    Something else that is odd - I just plugged in a 25Gbps SFP28 transceiver and got the same behavior - it appears in chassis hardware, but an interface is not created.
