7.3.1 "Current Multicast Groups" web page
The table on this web page provides an overview of the current multicast groups created on
this MMS. These include multicast groups assigned as a result of IGMP snooping and
groups that are statically created.
Figure 7-1 "Current Multicast Groups" web page
The checkboxes indicate which port has been assigned to each individual group.
Please note that all multicast groups that are known to the switch, including the dynami-
cally detected groups that were not created manually, are shown on this web page.
The overview for group membership is based on the "dot1qTpGroupTable" SNMP group.
This table contains all groups (static entries and IGMP) and their members.
7.3.2 Creating static multicast groups
This web page is used to create and manage statically configured multicast groups. In order
to create a multicast group, enter the MAC address provided (see "Multicast addresses" on
page 142) for the multicast group in the "Multicast Group Address" field, add the ports of the
data paths to the group members, and confirm these entries by entering a valid password.
If a group address is entered as an IP address, the IP address is converted into a multicast
MAC address according to the specifications of IEEE 802.1 D/p.
Overwriting a dynamic group with a static configuration means that a new port assignment
for this group cannot be created dynamically. Port assignment for this group can only be
started dynamically once the group has been deleted.
The guidelines for converting a multicast IP addresses into a multicast MAC address require
mapping of different IP groups to the same MAC group. Avoid the use of IP groups that
– Do not differ in the first and second byte from the right
– Differ by 128 in the third byte from the right
