Create a New VLAN.
Code

vlan create <vlan_id> name <vlan_name> type port
Replace <vlan_id> with the desired VLAN ID (e.g., 10, 20) and <vlan_name> with a descriptive name.
Assign Ports to a VLAN (Untagged/Access Port):
Code

vlan members <vlan_id> <port_list> untagged
Replace <vlan_id> with the VLAN ID and <port_list> with the port(s) you want to assign to this VLAN (e.g., 1/1, 1/5-1/10). Untagged ports are typically used for end devices.
Assign Ports to a VLAN (Tagged/Trunk Port):
Code

vlan members <vlan_id> <port_list> tagged
Replace <vlan_id> and <port_list> accordingly. Tagged ports are used for inter-switch links or connections to devices that understand 802.1Q tagging.
Set the Port VLAN ID (PVID) for a Port:
Code

interface ethernet <port_number>
pvid <vlan_id>
exit

Replace <port_number> with the specific port (e.g., 1/1) and <vlan_id> with the VLAN ID that untagged traffic entering this port should be assigned to. This is crucial for access ports. Verify VLAN Configuration.
Code

show vlan
show vlan port <port_number>
Save the Configuration.
Code

save config

Example: Creating VLAN 10 and assigning port 1/1 as an untagged member:
Code

config
vlan create 10 name DataVLAN type port-based
vlan members 10 1/1 untagged
interface ethernet 1/1
pvid 10
exit
save config
