|
VlanName
|
Specifies the name of the IGMP VLAN.
|
QueryInterval
|
The frequency (in seconds) at which IGMP host query packets are transmitted on the interface. The range is from 1 to 65535, and the default is 125.
|
MaxResponseTime
|
The maximum response time (in seconds) advertised in IGMPv2 general queries on this interface.
Smaller values allow a router to prune groups faster. The range is from 0 to 255, and the default is 100 tenth seconds.
Note: This value must be less than the QueryInterval.
|
Robustness
|
This parameter allows tuning for the expected packet loss of a network. This value is equal to the number of expected query packet losses per serial query interval, plus 1. If a network is expected to lose query packets, the robustness value should be increased.
The range is from 1 to 255, and the default is 2. The default value of 2 means that one query per query interval may be dropped without the querier aging out.
|
LastMemberQueryInterval
|
The maximum response time (in seconds) that is inserted into group-specific queries sent in response to leave group messages. It is also the time between group-specific query messages.
Decreasing the value reduces the time to detect the loss of the last member of a group. The range is from 1 to 65535, and the default is 1 second. Nortel recommends values above 1.
|
HostTimeout
|
The timer value for sending IGMP query packet when none was sent by the host in the LAN. The timer works on a per-VLAN basis. The device will send the query message if the timer is expired. The range is 1 to 16711450 with a default value of 260.
|
RouteTimeout
|
The amount of time a host must wait after hearing a Query before it sends any IGMPv2 messages. The default value is 260. The range is from 1 to 16711450 seconds.
|
LeaveTimer
|
The frequency (in seconds) at which a querier sends Group specific queries to group members when the querier receives a leave group message. The range is from 1 to 16711450 with a default value of 1.
|
QueryState
|
The current operational state of the IGMP query (enabled or disabled).
|
CurrentState
|
The current state of the IGMP (querier or non-querier).
|
IGMPSnoopingState
|
The current state of IGMP snoop (disabled or enabled) for this entry. To enable or disable the current state, click on the field and a selection box appears with the enable and disable options.
