Virtual Local Access Networks (VLANs)

VLANs allow for the logical grouping of switch interfaces, enabling communication as if all connected devices were on the same isolated network.

Configuration commands

(switch#) Create VLAN:

vlan <VLAN>

(switch#) Configure an interface to associate it with a VLAN:

interface <IFACE>
no shutdown
no routing

(switch#) Configure an interface as an access port:

vlan access VLAN

(switch#) Configure an interface as a trunk port:

vlan trunk native <VLAN>
vlan trunk allowed <VLAN>

(switch#) Configure VLAN as voice:

NOTE In order to give a specific VLAN a voice designation and add the proper hooks, it is necessary to add the voice command in the VLAN context. This configuration is the same for all CX-series switches.

vlan <VLAN>
voice

Show commands to validate functionality

(switch#)

show vlan [VLAN]

Example output:

show vlan
--------------------------------------------------------------------------------------
VLAN  Name                              Status  Reason          Type      Interfaces
--------------------------------------------------------------------------------------
1     DEFAULT_VLAN_1                    up      no_member_port  static    1/1/2
10    VLAN10                            up      ok              static    1/1/1-1/1/2

Expected results

  • Administrators can create a VLAN.
  • Administrators can assign a VLAN to the physical interface.
