Description
Specify the name of the VLAN ID.
Specify the name of the VLAN for which IGMP snooping querier is to be configured.
Here is displayed the rate of IGMP control packets that the Switch can process on a
specific VLAN. The rate is specified in packet per second. The packets that exceed
the limited rate will be dropped.
Displays the querier IP address
Displays the querier expiry time.
Specify the amount of time in seconds between general query transmissions. The
default setting is 125 seconds..
Specify the maximum time in seconds to wait for reports from members. The default
setting is 10 seconds.
Provides fine-tuning to allow for expected packet loss on a subnet. The value of the
robustness value is used in calculating the following IGMP message intervals: By
default, the robustness variable is set to 2.
Specify the maximum amount of time between group-specific query messages,
including those sent in response to leave-group messages. You might lower this
interval to reduce the amount of time it takes a router to detect the loss of the last
member of a group.
Specify the data driven group lifetime in seconds.
Specify to enable or disable the querier state.
Enable or disable the IGMP snooping fast leave function. If enabled, the membership
is immediately removed when the system receive the IGMP leave message.
If the state is enabled, it allows the Switch to be selected as a IGMP Querier (sends
IGMP query packets). If the state is disabled, the Switch cannot play the role as a
querier.
NOTE: If the Layer 3 router connected to the Switch provides only the IGMP proxy
function but does not provide the multicast routing function, then this state
must be configured as Disabled. Otherwise, if the Layer 3 router is not selected
as the querier, it will not send the IGMP query packet. Since it will not also
send the multicast-routing protocol packet, the port will be timed out as a router
port.
When enabled, multiple IGMP reports or leave for a specific (S, G) will be integrated
into one report only before sending to the router port.
Specify to enable or disable the data driven learning state.
Specify to enable or disable the data drive learning aged out option.
Specify the version of IGMP packet that will be sent by this VLAN.
Displays the querier role.
