Nortel Networks 350 manual Igmp Configuration Screen Fields, Snooping, Proxy, Robust Value

Using the Console Interface

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 spacebar to toggle to any existing IGMP VLAN configurations (the
	maximum number of VLANs that can be displayed is 64).
	Default Value:	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 losses 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
