is configured in the attached VLAN, and unregistered-flooding is
disabled, any subsequent multicast traffic not found in the table is
dropped, otherwise it is flooded throughout the VLAN.
Forwarding Priority – Assigns a CoS priority to all multicast traffic.
◆
(Range: 0-7, where 7 is the highest priority)
This parameter can be used to set a high priority for low-latency
multicast traffic such as a video-conference, or to set a low priority for
normal multicast traffic not sensitive to latency.
◆ Version Exclusive – Discards any received IGMP messages which use
a version different to that currently configured by the IGMP Version
attribute. (Default: Disabled)
IGMP Unsolicited Report Interval – Specifies how often the
◆
upstream interface should transmit unsolicited IGMP reports when
proxy reporting is enabled. (Range: 1-65535 seconds, Default: 400
seconds)
When a new upstream interface (that is, uplink port) starts up, the
switch sends unsolicited reports for all currently learned multicast
channels via the new upstream interface.
This command only applies when proxy reporting is enabled.
Router Port Expire Time – The time the switch waits after the
◆
previous querier stops before it considers it to have expired.
(Range: 1-65535, Recommended Range: 300-500 seconds,
Default: 300)
◆ IGMP Snooping Version – Sets the protocol version for compatibility
with other devices on the network. This is the IGMP Version the switch
uses to send snooping reports. (Range: 1-3; Default: 2)
This attribute configures the IGMP report/query version used by IGMP
snooping. Versions 1 - 3 are all supported, and versions 2 and 3 are
backward compatible, so the switch can operate with other devices,
regardless of the snooping version employed.
Querier Status – When enabled, the switch can serve as the Querier,
◆
which is responsible for asking hosts if they want to receive multicast
traffic. (Default: Disabled)
