Table 3-20 describes the IGMP Configuration screen fields.
Table 3-20. 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
