Modular Ethernet Switch User’s Guide
Web-Based Network Management

This screen allows you to
Enable
or
Disable
Group Multicast Registration Protocol (GMRP) globally for each
port. When GMRP is
Enabled,
a user attached to the port’s Ethernet segment can dynamically join a
multicast group. When GMRP is
Disabled,
then no dynamic multicast group registration is allowed on this
port.
Click on the
Static Multicast Forwarding
icon to access the following window:
Figure 7-41. Static Multicast Forwarding window
The fields you can set are:
♦
VID
Enter a VLAN ID from 1 to 4094. This is the VLAN that will be defined on this screen. VID 1 is the
default VLAN. All ports are designated members of VID 1 when VLANs are enabled.
♦
MAC Address
This is the MAC address of a user that will statically receive multicast packets.
♦
Egress/Forbidden/Non-Member
Position the cursor over the dash “–“ representing the appropriate
port number and press <space bar> to select
E
for Egress,
F
for Forbidden or leave the dash “–“. An
E
designates the specified port as a static member of the multicast group. An
F
defines the port as a non-
member and also forbids the port from joining the multicast group dynamically. A dash (–) means the port
is not given multicast group membership for the VID entered above.
♦
State<Permanent >
can be toggled between
Permanent, Delete on Reset, Delete on Timeout,
and
Invalid. Permanent
marks the entry as always being a member of the multicast group.
Delete
on Reset
marks the entry as active until the switch is reset (rebooted), at which time, the entry will be
deleted.
Delete on Timeout
marks the entry as active until the IGMP age-out timer expires. If the
IGMP age-out timer expires, the entry will be deleted.
Invalid
marks the entry to be deleted
immediately
Port-based VLANs
Port-based VLANs are a simplified version of 802.1Q VLANs. In port-based VLANs, each port can only belong
to one VLAN, with all traffic remaining inside the VLAN.
