Assigning a filter or filter set to a profile connection
A Multicast Filter or a Multicast Filter Set can be associated with one or more server profile Ethernet
connections.
• If IGMP snooping is enabled, the defined filters are active after they are associated with a profile
connection.
• When IGMP snooping is disabled, you can still configure filters and assign them to profiles; however,
IGMP filtering will not be in effect.
When an IGMP report on a VC port is received, all of the filters configured for the port are searched for a
match to the multicast group IP address. When a match is found, the report is processed and the group
membership is updated. If no match is found, IGMP v1 and v2 reports and Leave messages are
dropped. IGMPv3 reports are dropped if no record in the report matches any of the configured filter rules.
The report is relayed if there is at least one record matching any of the filter rules configured for the profile
Enet connection. The default action is ‘deny’.
If no filters are configured for a given profile connection, VC snoops all IGMP reports received on that port.
Multicast filters can be associated with profile connections (server downlink ports) and apply to the Ethernet
network associated with the connection. Filters cannot be associated with uplink or stacking link ports.
IGMP Settings (Multicast Filter Set) screen
A multicast filter set allows server ports to have multiple multicast filters assigned to them. Administrators can
create a multicast filter set by grouping multicast filters using some unique criteria such as service-based
grouping. Users can create a maximum of 128 filter sets in a domain. The Multicast Filter Set screen is
accessible to all users, but only users with domain, server, or network role permissions can add, edit, and
delete multicast filter sets.
To view filters that are members of a multicast filter set, click the multicast filter set name.
To add a multicast filter set:
1. Click Add.
2. Enter a unique name for the set. The name can consist of up to 64 alphanumeric characters, including
the hyphen (-), underscore (_), and period (.).
