Cisco-Guest and Cisco-Voice VLANs
It is important to note that you can assign all ports, regardless of their Smartports
role, to the default VLAN (default). If your network requires segregating either or
both voice and guest traffic and if you create additional VLANs, you must also
create these VLANs:
• Cisco-Guest—The VLAN to which all ports that are applied with the Guest
port role must be assigned. This VLAN ensures that all guest and visitor
traffic is segregated from the rest of your network traffic and resources.
•
Cisco-Voice—The VLAN to which all ports that are applied with the
IP Phone+Desktop port role must be assigned. This VLAN ensures that all
voice traffic has better quality of service and is not mixed with data traffic.
Note
The VLAN names, Cisco-Guest and Cisco-Voice, are case sensitive.
Only ports with the Guest port role can be assigned to the Cisco-Guest VLAN.
Only ports with the IP Phone+Desktop port role can be assigned to the
Cisco-Voice VLAN.
Create, Modify, and Delete VLANs
Prerequisites
Using only the default VLAN might be sufficient based on the size and
requirements of your network. We recommend that you first determine your
VLAN needs before creating VLANs. If you decide to create additional VLANs,
you must also create VLANs specifically for guest and voice traffic. The names
for these VLANs, Cisco-Guest and Cisco-Voice, are case sensitive. For more
information, see the
“Cisco-Guest and Cisco-Voice VLANs” section on
page 3-16 .
To create a VLAN, you must give the VLAN a name and a unique ID number. You
can create up to 32 VLANs.
You can modify the name of a VLAN but not its number. You cannot modify or
delete the default VLAN.
