Source Port(s) The source port filter set's slot and port(s).
2.14.5 show mac-address-table staticfiltering
This command displays the Static Filtering entries in the Multicast Forwarding
Database (MFDB) table.
Format
show mac-address-table staticfiltering
Mode Privileged EXEC
Mac Address A unicast MAC address for which the switch has forwarding and or
filtering information. The format is 6 or 8 two-digit hexadecimal num-
bers that are separated by colons, for example 01:23:45:67:89:AB. In
an IVL system the MAC address will be displayed as 8 bytes.
Type The type of the entry. Static entries are those that are configured by the
end user. Dynamic entries are added to the table as a result of a learn-
ing process or protocol.
Description The text description of this multicast table entry.
Interfaces The list of interfaces that are designated for forwarding (Fwd:) and fil-
tering (Flt:).
2.15 IGMP Snooping Configuration Commands
This section describes the commands you use to configure IGMP snooping.
FASTPATH software supports IGMP Versions 1, 2, and 3. The IGMP snooping feature
can help conserve bandwidth because it allows the switch to forward IP multicast
traffic only to connected hosts that request multicast traffic. IGMPv3 adds source
filtering capabilities to IGMP versions 1 and 2.
2.15.1 set igmp
This command enables IGMP Snooping on the system (Global Config Mode) or an
interface (Interface Config Mode). This command also enables IGMP snooping on a
particular VLAN (VLAN Config Mode) and can enable IGMP snooping on all
interfaces participating in a VLAN.
If an interface has IGMP Snooping enabled and you enable this interface for routing or
enlist it as a member of a port-channel (LAG), IGMP Snooping functionality is
disabled on that interface. IGMP Snooping functionality is re-enabled if you disable
routing or remove port-channel (LAG) membership from an interface that has IGMP
Snooping enabled.
The IGMP application supports the following activities:
• Validation of the IP header checksum (as well as the IGMP header checksum) and
discarding of the frame upon checksum error.
• Maintenance of the forwarding table entries based on the MAC address versus the
IP address.
• Flooding of unregistered multicast data packets to all ports in the VLAN.
