MLD Snooping-proxy VLAN Filtering
Use this screen to configure the Switch’s MLD filtering settings.
Click the Filtering link in the
Advanced Application > Multicast > IPv6 Multicast > MLD Snooping-proxy screen to
display the screen as shown.
Leave Mode
Select the leave mode for the specified downstream port(s) in this VLAN.
This specifies whether the Switch removes an MLD snooping membership entry
(learned on a downstream port) immediately (Immediate) or wait for an MLD
report before the leave timeout (Normal) or fast leave timeout (Fast) when an
MLD leave message is received on this port from a host.
Leave Timeout
Enter the MLD snooping normal leave timeout (in milliseconds) the Switch uses
to update the forwarding table for the specified downstream port(s).
This defines how many seconds the Switch waits for an MLD report before
removing an MLD snooping membership entry (learned on a downstream port)
when an MLD Done message is received on this port from a host.
Fast Leave Timeout
Enter the fast leave timeout (in milliseconds) for the specified downstream
port(s).
This defines how many seconds the Switch waits for an MLD report before
removing an MLD snooping membership entry (learned on a downstream port)
when an MLD Done message is received on this port from a host.
Apply
Click Apply to save your changes to the Switch’s run-time memory. The Switch
loses these changes if it is turned off or loses power, so use the Save link on the
top navigation panel to save your changes to the non-volatile memory when you
are done configuring.
Cancel
Click Cancel to reset the fields to your previous configuration.
