Chapter 1: Changes to Local Management Screens
1-46 Local Management Supplement
IGMP is enabled or disabled by VLAN, not port by port.
The following multicast routing protocols are transparently supported and
are used only to detect the location of the routers (see the Release Notes
for any changes or additions to this list):
• DVMRP (Distance Vector Multicast Routing Protocol, RFC 1075)
• PIM (Protocol Independent Multicast) version 1 and 2
• CBT (Core Based Trees)
• MOSPF (Multicast OSPF, RFC 1583)
For additional information about IGMP, refer to Appendix A.
To access the IGMP/VLAN Configuration screen from the Layer 3
Extensions Menu screen, use the arrow keys to highlight the
IGMP/VLAN CONFIGURATION menu item and press ENTER. The
IGMP/VLAN Configuration screen displays.
NOTE
Certain versions of firmware will not allow the switch to be a
querier. Please check your release notes for further
information. Refer to RFC 2236, Section 8, for more
information on IGMP.
NOTE
The IGMP/VLAN Configuration screen does not display when
the operational mode of the device is set to SECURE FAST
VLAN.
Your SmartSwitch device user’s guide provides instructions for
setting the operational mode.
