These parameters are displayed:
Proxy Switching – Configures MVR proxy switching, where the source
◆
port acts as a host, and the receiver port acts as an MVR router with
querier service enabled. (Default: Enabled)
When MVR proxy-switching is enabled, an MVR source port serves
■
as the upstream or host interface, and the MVR receiver port serves
as the querier. The source port performs only the host portion of
MVR by sending summarized membership reports, and
automatically disables MVR router functions.
Receiver ports are known as downstream or router interfaces.
■
These interfaces perform the standard MVR router functions by
maintaining a database of all MVR subscriptions on the downstream
interface. Receiver ports must therefore be configured on all
downstream interfaces which require MVR proxy service.
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.
