Switching

Hi, I'm new to juniper. how to add vlan to trunk port and how to verify if its done correctly?

Hi,

First add a vlan to the switch if that has not been done already

>set vlan vlan-name vlan-id id

Create the vlan on the switch

set vlan test vlan-id 20

set the vlan to the interface

set interfaces ge-0/0/0 unit 0 family ethernet-switching vlan members test

you can replace the ge-0/0/0 by any interface you want to add the vlan to

To check if the vlan is on the trunk

show interfaces ge-0/0/0

description test;
unit 0 {
    family ethernet-switching {

        port-mode trunk;
        vlan {
            members [ TEST-1 test];
        }
    }
}

now you need to apply the config to the switch with the commit command

commit.

and you are done 🙂

Thanks. is that access port or trunk port? I'm looking see how to add vlans to trunk port, how to remove vlan from trunk port?

assume trunk port has vlan 10,20,30,40. I want to add vlan 50 to the trunk port and then remove vlan 10 from the trunk port, how to do that?

what command to use for verification?

The same command marc showed you to add a vlan to the trunk port, you would then use replace the word "set" with "delete" to remove a vlan. Commit the configuration and it will be gone

>show vlans extensive

as @lyndidon is suggesting... you van remove it with the following command

delete interfaces ge-0/0/0 unit 0 family ethernet-switching vlan members test
