C HAPTER 4 | Configuring the Switch
Multicast VLAN Registration
– 139 –
By default, the system automatically detects the speed and duplex
mode used on each port, and configures the path cost according to the
values shown in Table 9 , Table 10 and Table 11 .
◆ Priority – Defines the priority used for this port in the Spanning Tree
Algorithm. If the path cost for all ports on a switch are the same, the
port with the highest priority (i.e., lowest value) will be configured as
an active link in the Spanning Tree. This makes a port with higher
priority less likely to be blocked if the Spanning Tree Algorithm is
detecting network loops. Where more than one port is assigned the
highest priority, the port with lowest numeric identifier will be enabled.
(Range: 0-240, in steps of 16; Default: 128)

M ULTICAST VLAN R EGISTRATION
Multicast VLAN Registration (MVR) is a protocol that controls access to a
single network-wide VLAN most commonly used for transmitting multicast
traffic (such as television channels or video-on-demand) across a service
provider’s network. Any multicast traffic entering an MVR VLAN is sent to
all attached subscribers. This protocol can significantly reduce to
processing overhead required to dynamically monitor and establish the
distribution tree for a normal multicast VLAN. This makes it possible to
support common multicast services over a wide part of the network
without having to use any multicast routing protocol.
