DES-3326 Layer 3 Fast Ethernet Switch User’s Guide
Layer 3 Multicasting
When the switch is in IP Routing mode, several functions supporting IP multicasting are added to the
Multicasting menu.
Multicast Interface Configuration
To setup IP multicasting on the switch:
Open the Multicasting menu (under Configuration), select IP Multicasting, and click Multicast
Interface Configuration:
.
Figure 7-42. Multicast Interface Configuration window
This menu allows the assignment of a multicast routing protocol to an IP interface. The IP interface
must have been previously configured on the switch.
In addition, IGMP may be enabled or disabled for the selected IP interface.
The available multicast protocols are the Protocol Independent Multicast – Dense Mode (PIM-DM),
and the Distance-Vector Multicast Routing Protocol (DVMRP).
INACT is not a multicast routing protocol. It is used to make a given interface inactive for IP Multicast
routing and can still route IP traffic.
The following fields can be set:
Parameter Description
Interface Name
Allows the entry of the name of the IP interface that is to be
configured for multicasting. This must be a previously
configured IP interface.
IGMP <Enabled> This field can be toggled between Enabled and Disabled
using the pull-down menu. This will enable or disable IGMP
for the IP interface entered above.
Multicast Routing
Protocol <INACT>
This field can be toggled between Protocol Independent
Multicasting – Dense Mode (PIMDM), Distance Vector
Multicasting Routing Protocol (DVMRP), and INACT
(inactive). INACT is not a multicast routing protocol. It is
used to make a given interface inactive for IP Multicast
routing yet can still route IP traffic.
