  • 1.  EX4200 VC port options are only 0-23 on a 48 port switch

    Posted 05-30-2018 21:02

    We have a EX4200 that is connected to a 2200-c and it was never put into VC.  Before someone says something about "best practices" these two are on separate floors and will never saturate a 1GB link the VC is strictly for configuration ease.  Anyway, upon setting up the 4200 it was discovered that the only port options are 0..23.  It is a ex4200-48px and I am confused why I can't select port 47. (which is where the 2200-c is connected)  The 2200-c has the option of 0..47 and it's a little guy.  Both switches are using the best practice firmware (12.3R12-S7).  I fired up an old lab ex4200-48t and same thing.  only options 0..23 when it comes to the port settings (older 12.3 firmware)

     

    User493@MAIN4200> request virtual-chassis vc-port set pic-slot 0 port ?
    Possible completions:
  <port>               Port number (0..23)
{master:0}

    I am just wonder why this is and is there a way to change it.  Thanks in advanced

    QFX5200, EX3400, EX3300, EX2300, and EX2200 switches cannot be part of any mixed Virtual Chassis.

     

    taken from documentation

    https://www.juniper.net/documentation/en_US/junos/topics/concept/virtual-chassis-ex-qfx-series-mixed-understanding.html

     

    additionally:

    EX4200

    2 ports on rear panel

    None

    Any uplink module ports (SFP, SFP+, or XFP) or through an SFP+ port on the EX4200-24F switch

    Note: You cannot set a 1000BASE-T copper SFP transceiver (EX-SFP-1GE-T) connection as a VCP on EX4200 switches.

     

    regards

    Well that halts that project.  Thanks for that link!  Also about thre sfp!  That was going to be the next test.  Still though,  why can the ex4200 only use ports 0-23?  I guess it really doesn't matter at this point just curious
