IGMP Configuration Screen Fields

 

 

 

Field

Description

 

 

 

VLAN

Allows you to set up or view IGMP VLAN configurations on specified VLANs. You

 

can use the space bar to toggle to any existing IGMP VLAN configurations (the

 

maximum number of VLANs that can be displayed is 64).

 

Default

1

 

Range

1 to 4094

Snooping

Allows you to enable or disable IGMP Snooping.

 

This field affects all VLANs (for example, if you disable snooping on the VLAN

 

specified in the screen’s VLAN field, ALL VLANs are disabled for snooping).

 

Default Value

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 on the VLAN specified

 

in the screen’s VLAN field, ALL VLANs are disabled for proxy). The Proxy field

 

cannot be disabled unless the Snooping field is Enabled.

 

Default Value

Enabled

 

Range

Enabled, Disabled

Robust Value

Allows a user 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 Value

2

 

Range

1 to 64
