EX2200 I would like to set 4 ports for WAN usage

    I have EX2200 configured with some vlans but I would like to sacrifice 4 ports be configured as "unmanaged" to work with WAN ISP - I need extra 4 ports for that purpose so I can connect 3 device and ISP WAN.

     

    Basically, instead of placing an unmanaged switch, I would like to use these 4 ports. Should the config looks like this:

     

    interfaces {
    ge-0/0/0 {
    unit 0 {
    family ethernet-switching {
    storm-control default;
    }
    }
    }
    ge-0/0/1 {
    unit 0 {
    family ethernet-switching {
    storm-control default;
    }
    }
    }
    ge-0/0/2 {
    unit 0 {
    family ethernet-switching {
    storm-control default;
    }
    }
    }
    ge-0/0/3 {
    unit 0 {
    family ethernet-switching {
    storm-control default;
    }
    }
    }
     
    rstp {
    interface ge-0/0/0;
    interface ge-0/0/1;
    interface ge-0/0/2;
    interface ge-0/0/3;
     
    do I need anything else?

    What else do you have on the ex2200?

    The configuration you have will put these four ports into your current switch default vlan which is likely and internal one.

     

    I assume you want to isolate these four ports from all the internal vlans.  So you have two options:

     

    option 1 - layer 2 only vlan

    Create a new vlan with an unused vlan tag value to assign to all four ports.

    Make sure there are no layer 3 interfaces in this vlan so they cannot communicate with anything else

    I doubt you need to worry about loops on these ports to the upstream routers or firewalls so the rstp is probably not needed

     

    option 2 - isolated routing instance

    This will create more separation and guarantee no access to internal vlans

    Create a virtual router routing instance

    Assign all 4 ports to this routing instance

    The configuration you posted as just ethernet switching without need for vlans will work

    Thank you Steve,

     

    I have few ports used by trunks so this option would be perfect:

     

    option 1 - layer 2 only vlan

    Create a new vlan with an unused vlan tag value to assign to all four ports.

    Make sure there are no layer 3 interfaces in this vlan so they cannot communicate with anything else

    I doubt you need to worry about loops on these ports to the upstream routers or firewalls so the rstp is probably not needed

     

    Thank you

    Hello,

     

    You can create a separate vlan with 'set vlans test vlan-id <ID>' command.

    And then you can put interfaces from ge-0/0/0 to ge-0/0/3 in the VLAN created using command:

    'set vlans test interface <interface name>'

     

    This should put all these interfaces as L2 access interfaces in specific vlan.

     

    Regards,
