interface fastEthernet 0/3 switchport mode access switchport access vlan 20 no shutdown Use show vlan brief to verify that Fa0/1 is now in VLAN 10 and Fa0/2 is in VLAN 20. If ports still show up as "VLAN 1 (default)," you forgot the switchport access vlan command. Phase 2: Trunk Configuration (Connecting Switches) Without trunks, SW1’s VLAN 10 traffic cannot reach SW2’s VLAN 10. Trunks using IEEE 802.1Q add a VLAN tag to each frame. cisco+lab+162
In the journey to earning a Cisco certification—whether it’s the CCNA, CCNP, or simply mastering enterprise networking—lab exercises are the proving ground. Among the myriad of labs found in Cisco NetAcad, OCG workbooks, and Packet Tracer activities, Cisco Lab 162 stands out as a pivotal challenge. While lab numbers can vary slightly between curriculum versions (e.g., 1.6.2, 10.3.5, or 16.2), "Cisco Lab 162" universally refers to a comprehensive topology focused on VLAN segmentation, trunking, and Inter-VLAN routing . interface gigabitEthernet 0/0
