  • 1.  Port channel with sub interface config on MX

    Posted 04-04-2015 21:18


    I am new to the JunOS platform and I wanted to create a port channel with sub interface on a MX 480 router.


    I have a logical system and I want the port channel sub interface to be part of the logical system with an encap of vlan id 50 and ip of . I am not sure of how the cli's are as I a coming from the Cisco world 😞


    Also the other side of the port channel is on a Palo alto firewall which also has an ae configured with a sub interface configured for vlan 50.


    Appreciate your help.

    You need to allow the system to have aggregated-devices:


    set chassis aggregated-devices ethernet device-count 1

    ( if you need more devices change the number to the devices you need)


    Next step is to put the interfaces you want to you in the ae bundle:  ( you can add to upto 8 interfaces in an ae Bundle)


    set interfaces ge-0/1/0 description "ge-0/1/0 <---> ge-1/0/0.otherdevice"
    set interfaces ge-0/1/0 ether-options 802.3ad ae0


    set interfaces ge-0/2/0 description "ge-0/2/0 <---> ge-2/0/0.otherdevice"
    set interfaces ge-0/2/0 ether-options 802.3ad ae0


    #Configure the ae0 interface (bundled ae device)

    set interfaces ae0 description " <---> aeX.otherdice"
    set interfaces ae0 aggregated-ether-options link-speed 1g
    set interfaces ae0 aggregated-ether-options lacp active


    #allow vlan tagging on the bundled ae interface

    set interfaces ae0 vlan-tagging


    #config the vlan tag on the sub-interface and IP 

    set interfaces ae0 unit 50 description "vlan50"

    set interfaces ae0 unit 50 vlan-id 50

    set interfaces ae0 unit 50 family inet address


    #add the interface to your logical system

    set routing-instances <name-of-logical-system> interface ae0.50


    Hope this helps you a little
