  • 1.  EX4100 - PIC1 and PIC2 require 10G?

    Hello - low hanging fruit question here ...

    I have an EX4100-48-T which I have executed the following command to convert the dedicated VC-interfaces for standard networking interfaces:

    request virtual-chassis mode network-port


    Question: are 10G SFPs required for any of these 8 interfaces, or will 1G SFPs work?

    I was attempting to use 1G SFPs, and although I got link and the interface showed "up", I could get no traffic to transit.

    Thanks in advance!

    I recently had a similar experience with the EX2300.  I discovered the 1g revenue interfaces cannot be used as vc-ports.  Only the 10g sfp+ ports can be used as vc-ports.  I'm seeing in the link below, your EX4100 may need to use either 25g or 10g interfaces.

    Details about the dedicated, default and ports that we can configure as Virtual chassis ports in [EX/QFX] (juniper.net)

    another EX4100 VC related link that may be helpful....

    Hi,

    On the EX4100s all 8 ports can be used at 1GB, As Aron mentioned in VC mode it needs to be 10GB or 25GB, but in network mode you should be able to use 1GB. if you share your config for these ports that may help.

    Hi Harry - 

    I will post the simple configure of one of the interfaces below:

    set interfaces ge-0/2/0 unit 0 description "drop from isp"
    set interfaces ge-0/2/0 unit 0 family ethernet-switching interface-mode access
    set interfaces ge-0/2/0 unit 0 family ethernet-switching vlan members isp
    

    As already stated, I tried 1g SFPs and the interface would shop 'up', however no traffic would pass nor would the interface 'learn' the MAC of the upstream router.

    Do I need to configure the interfaces as xe-0/2/0 and then hardset the speed for 1g?

    Regards!

    Does the ports show UP/UP on both devices?

    In the past I have used 1G SFP between EX4100-F-12 and EX2300-C12, and it would not come up unless auto-negotiation was disabled.

    Switch last 5 ports support 10-G support you can insert  last port and check .

    My configuration is very simple: below is the configuration for those interfaces specifically:

    set interfaces ge-0/2/0 unit 0 description "ISP Drop"
    set interfaces ge-0/2/0 unit 0 family ethernet-switching interface-mode access
    set interfaces ge-0/2/0 unit 0 family ethernet-switching vlan members ISP
    

    Do I need to configure this as xe-0/2/0 and then hard-set the speed to 1g?

    As stated earlier, I tried 1g SFPs, and although link would come up, traffic would not pass nor would the interface learn the MAC address of the ISP.

    Regards!

    It is correct to use ge-0/2/0 (and not xe-).

    You need to check if the device on the other side of the link also shows UP.

    Thanks you - I also noticed the PR advising to disable auto-negotiate is almost 1 year old, also that Juniper's recommended firmware release is now: 22.4R3-S2.

    I will attempt to upgrade the firmware to see if this resolves the issue.  What a horrible thing for Juniper to not have fixed by assuming one has admin access to both ends... just freaking horrible.

    Thank you - I'm thinking it is the no-auto-negotiate issue, however I do not have administrative access to the ISP hardware. 

    That being said, I see the PR that was listed is almost 1 year old, and that as of 3 days ago, Juniper's recommended release has been changed to 22.4R3-S2.

    I am hoping a firmware upgrade resolves this issue.  I will post my results here as soon as I perform the upgrade.
