Cisco Nexus 7000 Series NX-OS Multicast Routing Configuration Guide
138
Description
Sets the interval that the software waits after sending
an IGMP query to verify that no hosts that want to
receive a particular multicast group remain on a
network segment. If no hosts respond before the last
member query interval expires, the software removes
the group from the associated VLAN port. Values
range from 1 to 25 seconds. The default is 1 second.
Configures Optimized Multicast Flood (OMF) on
specified VLANs. The default is enabled.
Configures IGMP snooping proxy for the specified
VLANs. The default is 5 seconds.
Configures a snooping querier on an interface when
you do not enable PIM because multicast traffic does
not need to be routed. You can also configure the
following values for the snooping querier:
• timeout—Timeout value for IGMPv2
• interval—Time between query transmissions
• maximum response time—MRT for query
messages
• startup count—Number of queries sent at startup
• startup interval—Interval between queries at
startup
Configures the robustness value for the specified
VLANs.
Limits the membership report traffic sent to
multicast-capable routers on a per-VLAN basis. When
you disable report suppression, all IGMP reports are
sent as is to multicast-capable routers. The default is
enabled.
Configures a static connection to a multicast router.
The interface to the router must be in the selected
VLAN.
Configures a Layer 2 port of a VLAN as a static
member of a multicast group.
Configures link-local groups suppression on a
per-VLAN basis. The default is enabled.
Configures IGMPv3 report suppression and proxy
reporting on a per-VLAN basis. The default is enabled
per VLAN.
