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.
