Layer 2 IGMP (Snooping and Query for IPv4)
– 582 –
Membership reports exceeding the configured limits for the interface are
dropped. This command can be used to prevent DoS attacks.
Rules Used for Proxy Reporting
When IGMP Proxy Reporting is disabled, the switch will use a null IP address for
the source of IGMP query and report messages unless a proxy query address
has been set.
When IGMP Proxy Reporting is enabled, the source address is based on the
following criteria:
■
If a proxy query address is configured, the switch will use that address as
the source IP address in general and group-specific query messages sent to
downstream hosts, and in report and leave messages sent upstream from
the multicast router port.
■
If a proxy query address is not configured, the switch will use the VLAN’s IP
address as the IP source address in general and group-specific query
messages sent downstream, and use the source address of the last IGMP
message received from a downstream host in report and leave messages
sent upstream from the multicast router port.
◆
Interface 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. (Options: 1-3, Using Global Version; Default: Using Global
Version)
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.
◆
Query Interval
– The interval between sending IGMP proxy general queries.
(Range: 2-31744 seconds; Default: 125 seconds)
An IGMP general query message is sent by the switch at the interval specified
by this attribute. When this message is received by downstream hosts, all
receivers build an IGMP report for the multicast groups they have joined.
This attribute applies when the switch is serving as the querier (page 570), or as
a proxy host when IGMP snooping proxy reporting is enabled (page 570).
◆
Query Response Interval
– The maximum time the system waits for a
response to general queries. (Range: 10-31740 tenths of a second in multiples
of 10; Default: 10 seconds)
This attribute applies when the switch is serving as the querier (page 570), or as
a proxy host when IGMP snooping proxy reporting is enabled (page 570).
