|
|
|
Field | Description |
|
|
| |
Snooping | Allows you to enable or disable IGMP Snooping. | |
| This field affects all VLANs (for example, if you disable Snooping for the VLAN | |
| specified in the screen’s VLAN field, Snooping is disabled for ALL VLANs). | |
| Default | Enabled |
| Range | Enabled, Disabled |
Proxy | Allows the switch to consolidate IGMP Host Membership Reports received on its | |
| downstream ports and to generate a consolidated proxy report for forwarding to its | |
| upstream neighbor. |
|
| This field affects all VLANs (for example, if you disable Proxy for the VLAN specified | |
| in the screen’s VLAN field, Proxy is disabled for ALL VLANs). You cannot set the | |
| Proxy field value to Disabled unless the Snooping field value is Enabled. | |
| Default | Enabled |
| Range | Enabled, Disabled |
Robust Value | Allows you to set the switch to offset expected packet loss on a subnet. If packet | |
| losses on a subnet are unacceptably high, the Robust Value field can be increased | |
| to a higher value. |
|
| This field affects only the VLAN specified in the screen’s VLAN field (for example, if | |
| you change the robust value on the VLAN specified in the screen’s VLAN field, other | |
| VLANs are not affected). | |
| Default | 2 |
| Range | 1 to 64 |
Query Time | Allows you to control the number of IGMP messages allowed on the subnet by | |
| varying the Query Interval (the Query Interval is the interval between general | |
| queries sent by the IP multicast router). | |
| This field affects only the VLAN specified in the screen’s VLAN field (for example, if | |
| you change the Query Time value field on the VLAN specified in the screen’s VLAN | |
| field, other VLANs are not affected). | |
| Default | 125 seconds |
| Range | 1 to 512 seconds |
