name and move member ports to another VLAN; or, you can exit to the Main Menu.

[R] Multicast Registration

By default, the switch forwards all multicast packets to all ports on the switch. To reduce the amount of
multicast flooding on the switch, you can register multicast addresses and list the ports to which these packets
are to be forwarded.
To display the Multicast Registration menu, enter the R option from the Main Menu. The following is a
Multicast Registration menu from the Catalyst 2820:

Registered multicast addresses: 1

[R] Register a multicast address
[L] List all multicast addresses
[U] Unregister a multicast address
[E] Erase all multicast addresses
[X] Exit to Main Menu
Enter Selection:
The first line of the menu displays the number of registered multicast addresses. The menu options are as
follows:
[R] Register a multicast address—Allows the addition of multicast addresses and ports to which
multicasts can be forwarded. Invalid multicasts—such as unicasts, broadcasts, and reserved
multicasts—are automatically rejected. The switch supports up to 64 IP multicast group registrations.
[L] List all multicast addresses—Displays all registered multicast addresses that exist in the switch.
[U] Unregister a multicast address—Removes registered multicast addresses.
[E] Erase all multicast addresses—Removes all registered multicast addresses from the switch's
address table.
[X] Exit to Main Menu—Displays the management console Main Menu.

[F] Firmware

Loading an upgraded version of the system software is fairly simple. When you download the firmware to
Flash memory, the switch does not respond to commands for approximately one minute. You should not turn
off the switch until after the switch resets and begins using the new firmware.
Note Cisco periodically provides new firmware to implement enhancements and maintenance releases. New
firm−ware releases can be downloaded from Cisco Connection Online (CCO), the Cisco Systems'
customer Web site, at http://www.cisco.com/.
When you enter the Firmware Configuration menu, your display will look similar to this:
