•
Forwarding Priority – Assigns a CoS priority to all multicast traffic. (Range: 0-6, where 6 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. This feature is not supported for IGMPv3
snooping. (Default: Disabled)
