Multicast VLAN Registration for IPv4
When the source port receives report and leave messages, it only
■
forwards them to other source ports.
When receiver ports receive any query messages, they are dropped.
■
When changes occurring in the downstream MVR groups are
■
learned by the receiver ports through report and leave messages,
an MVR state change report is created and sent to the upstream
source port, which in turn forwards this information upstream.
When MVR proxy switching is disabled:
■
Any membership reports received from receiver/source ports
■
are forwarded to all source ports.
When a source port receives a query message, it will be
■
forwarded to all downstream receiver ports.
When a receiver port receives a query message, it will be
■
dropped.
Robustness Value – Configures the expected packet loss, and thereby
◆
the number of times to generate report and group-specific queries.
(Range: 1-255; Default: 2)
This parameter is used to set the number of times report messages
■
are sent upstream when changes are learned about downstream
groups, and the number of times group-specific queries are sent to
downstream receiver ports.
This parameter only takes effect when MVR proxy switching is
■
enabled.
Proxy Query Interval – Configures the interval at which the receiver
◆
port sends out general queries. (Range: 2-31744 seconds;
Default: 125 seconds)
This parameter sets the general query interval at which active
■
receiver ports send out general queries.
This interval is only effective when proxy switching is enabled.
■
◆ Source Port Mode – Configures the switch to forward any multicast
streams within the parameters set by a profile, or to only forward
multicast streams which the source port has dynamically joined.
Always Forward – By default, the switch forwards any multicast
■
streams within the address range set by a profile, and bound to a
domain. The multicast streams are sent to all source ports on the
switch and to all receiver ports that have elected to receive data on
that multicast address. (This is the default setting.)
Dynamic – When dynamic mode is enabled, the switch only
■
forwards multicast streams which the source port has dynamically
joined. In other words, both the receiver port and source port must
subscribe to a multicast group before a multicast stream is
