VLAN Management

Customer Port Multicast TV VLAN

228 Cisco Small Business 200, 300 and 500 Series Managed Switch Administration Guide (Internal Version)

Packets from subscribers to the service provider network are forwarded as VLAN

tagged frames, in order to distinguish between the service types, which mean that

for each service type there is a unique VLAN ID in the CPE box.

All packets from the subscriber to the service provider network are encapsulated

by the access device with the subscriber’s VLAN configured as customer VLAN

(Outer tag or S-VID), except for IGMP snooping messages from the TV receivers,

which are associated with the Multicast TV VLAN. VOD information that is also

sent from the TV receivers are sent like any other type of traffic.

Packets from the service provider network that received on the network port to

the subscriber are sent on the service provider network as double tag packets,

while the outer tag (Service Tag or S-Tag) represent one of the two type of VLAN

as following:

• Subscriber’s VLAN (Includes Internet and IP Phones)

• Multicast TV VLAN

The inner VLAN (C-Tag) is the tag that determines the destination in the

subscriber’s network (by the CPE MUX).

Workflow

1. Configure an access port as a customer port (using the VLAN Management >

Interface Settings page). See QinQ for more information.

2. Configure the network port as a trunk or general port with subscriber and

Multicast TV VLAN as tagged VLANS. (using the VLAN Management > Interface

Settings page.

3. Create a Multicast TV VLAN with up to 4094 different VLAN(s). (The VLAN

creation is done via the regular VLAN management configuration)

4. Associate the customer port to a Multicast TV VLAN, using the Port Multicast

VLAN Membership page.

5. Map the CPE VLAN (C-TAG) to the Multicast TV VLAN (S-Tag), using the CPE

VLAN to VLAN page.

Mapping CPE VLANs to Multicast TV VLANs

To support the CPE MUX with subscribers VLANs, subscribers may require

multiple video providers, and each provider is assigned a different external VLAN.

CPE (internal) Multicast VLANs must be mapped to the Multicast provider

(external) VLANs.
