Interface, VLAN Trunk & Cek ARP

Membuat interface trunk dengan vlan-tagging, memberi unit (sub-interface) dengan vlan-id dan IP, lalu memverifikasi neighbor / MAC address dengan show arp.

bash

set interfaces et-0/0/2 description TO-SW-40G

STEP

Jadikan trunk dengan VLAN

1Aktifkan vlan-tagging pada interface
2Buat unit dengan description, vlan-id, dan IP

bash

edit interfaces et-0/0/2
set description TRUNK.SW.40G
set vlan-tagging
set unit 1000 description UPSTREAM.1
set unit 1000 vlan-id 1000
set unit 1000 family inet address 172.16.100.2/24

Cek MAC Address / ARP

STEP

Lihat tabel ARP

1Cek semua interface
2Cek ARP hanya pada interface tertentu

bash
