the ports to detect IGMP queries and report packets and manage IP multicast traffic
through the switch.
IGMP uses the following three fundamental types of messages:
Message Description
Query A message sent from the query (IGMP router or switch)
asking for a response from each host belonging to the
multicast group.
Report
A
message sent by a host to the query to indicate that the
host wants to be or is a member of a given group
indicated in the report message.
Leave Group A message sent by a host to the query to indicate that the
host is no longer a member of a specific multicast group.
5.9.2 Static MAC Address
When you add a static MAC address, it remains in the switch's address table, regardless
of whether the device is physically connected to the switch. This saves the switch from
having to re-learn a device's MAC address when the disconnected or powered-off device
is active on the network again.
To add a static MAC address:
1. From the Main Menu, select Administrator.
2. Select Filter Database.
3. Click Static MAC Addresses. In the MAC address box, enter the MAC address to
and from which the port should permanently forward traffic, regardless of the device's
network activity.
4. In the Port Number box, select a port number.
5. If tag-based (IEEE 802.1Q) VLANs are set up on the switch, static addresses are
associated with individual VLANs. Type the VID (tag-based VLANs) to associate with
the MAC address.
6. Click the Add button.
5.9.3 Port Security
A port in security mode will be “locked” without permission of address learning. Only the
