The individual fields on this screen are defined as follows:

Field Name

Description

Multicast Precedence

[Enable, Disable] When enabled, the lower the multicast, the IGMP packets will be put

higher in the queue.

Default Version

[1-3] Enter the supported IGMP version.

Query Interval

The interval at which the multicast router sends a query messages to hosts. Ex-

pressed in seconds.

If the number is below 128, the value is used directly. If the value is greater than 128,

it is interpreted as an exponent and mantissa.

Query Response Interval

Upon receiving a query packet, a host beings counting down seconds, from a random

number. When the timer expires, the host sends it’s report.

Enter a value for the maximum number of seconds for the range of random values a

host can pick to count down from. The value must be greater than the Query Interval.

If using IGMP v1, this value is fixed at 10 seconds.

Last Member Query Interval

Enter the maximum response time within which the host must respond to the Out of

Sequence query from the router.

(Default = 1000ms)

IGMP uses this value when router receives and IGMPv2 Leave report indicating at

least one host wants to leave the group. Upon receiving the Leave report, the router

confirms the interface is not configured for IGMP Immediate Leave. If not, the router

sends the out-of-sequence query.

Robustness Value

[2-7] Enter the value representing the complexity of the query. The greater the value,

the more robust the query.

Maximum Multicast Groups

Maxim number of groups allowed.

Maximum Multicast Data Sources (for

IGMP v3)

[1-24] Maximum data sources allowed.

Maximum Multicast Group Members

The maximum number of multicast groups that can be joined on a port or group of

ports.

Fast leave

[Enabled, Disabled] If enabled, the IGMP proxy removes group member immediately

without sending a query.

LAN to LAN (Intra LAN) Multicast

Check this option to permit a multicast data source on the LAN side and IGMP

snooping enabled.

Membership Join Immediate (IPTV)

When enabled, clients do not send a join report and will have faster join at startup but

only by a few milliseconds.
