Parameter | Description |
|
|
| |
IGMP Status | If enabled, the switch will monitor network traffic to determine | ||||
|
| which hosts want to receive multicast traffic. | |||
Act as IGMP Querier | If enabled, the switch can serve as the “querier,” which is | ||||
|
| responsible for asking hosts if they want to receive multicast | |||
|
| traffic. |
|
|
|
IGMP Query Count | The maximum number of queries issued for which there has been | ||||
|
| no response before the switch takes action to solicit reports. | |||
|
| (Range: 2 - 10.) |
|
|
|
IGMP Report Delay | The time (in seconds) between receiving an IGMP Report for an | ||||
|
| IP multicast address on a port before the switch sends an IGMP | |||
|
| Query out of that port and removes the entry from its list. | |||
