 S3300 Smart Managed Pro Switch
MVR Configuration
Use the MVR Configuration screen to enable MVR and to configure global MVR settings on 
the switch. 
 To configure basic MVR settings:
1.  Sele
ct Switching > MVR > Basic > MVR Configuration
2.  Next to MV
R Running select Enable.
3.  I
n the MVR Multicast VLAN field, specify the VLAN on which MVR multicast data will be 
received. 
All source ports belong to this VLAN. The value can be set in a range of 1 to 4093. The 
d
efault value is 1.
4.  In the MVR Glob
al query response time field, set the maximum time to wait for the IGMP 
reports membership on a receiver port. 
This time applies only to receiver-port lea
ve processing. When an IGMP query is sent 
from a receiver port, the switch waits for the default or configured MVR query time for an 
IGMP group membership report before removing the port from the multicast group 
membership. The value is equal to the tenths of second. The range is from 1 to 100 
tenths. The factory default is 5 tenths or one-half.
5.  From the MVR M
ode list, select the MVR mode of operation. 
• Dynamic. T
he MVR switch learns existing multicast groups by snooping the IGMP 
queries from router on source ports and forwarding the IGMP reports from the hosts 
to the IGMP router on the Multicast VLAN (with appropriate translation of the VLAN 
ID).
• Comp
atible. The MVR switch does not learn multicast groups; the groups have to be 
configured by the operator because MVR does not forward IGMP reports from the 
hosts (RP port) to the IGMP router (SP port). To operate in this mode, the IGMP 
router has to be statically configured to transmit all required multicast streams to the 
MVR switch.
The following table describes the global MVR status fields on the screen.

Field Definition
MVR Max Multicast Groups The maximum number of multicast groups that MVR supports. 
MVR Current Multicast Groups The current number of the MVR gro
ups allocated.
