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

Configure TV VLAN with the following steps:

1. Define a TV VLAN by associating a Multicast group to a VLAN (using the 

Multicast Group to VLAN page).

2. Specify the access ports in each Multicast VLAN (using the Port Multicast VLAN 

Membership page. 

To define the Multicast TV VLAN configuration:

Click VLAN Management > Access Port Multicast TV VLAN > Multicast Group to 
VLAN.

The following fields are displayed:

•

Multicast Group—IP address of the Multicast group. 

•

Multicast TV VLAN—VLAN to which the Multicast packets are assigned.

Click Add to associate a Multicast group to a VLAN. Any VLAN can be selected. 
When a VLAN is selected, it becomes a Multicast TV VLAN.

Group registration

All Multicast group 
registration is dynamic.

Groups must be associated 
to Multicast VLAN statically, 
but actual registration of 
station is dynamic.

Receiver ports

VLAN can be used to 
both send and receive 
traffic (both Multicast and 
Unicast).

Multicast VLAN can only be 
used to receive traffic by the 
stations on the port (only 
Multicast).

Security and 
Isolation

Receivers of same 
multicast stream are on 
the same data VLAN and 
can communicate with 
each other

Receivers of same multicast 
stream are in different 
Access VLANs and isolated 
from each other
