[A] Port Addressing

The Port Addressing menu allows you to set up security and to add static MAC addresses to a port. When entering this option, you must first identify a port to configure, as listed in Table 15.2.

Table 15.2: The available configurable ports on a Catalyst 2820 from the Port Addressing menu.

Following is the Port Addressing configuration menu:

Catalyst 2820 − Port 2 Addressing

Address: Static A0−00−F3−1F−11−34

——————————————————Settings——————————————————

——————————————————Actions——————————————————

[A] Add a static address

[D]Define restricted static address

[L]List addresses

[E]Erase an address

[R] Remove all addresses

——————————————————Related Menus——————————————————

Enter selection:

When the port is a secured port, its MAC address will be 00−00−00−00−00−00. The following is the list of options and parameters for the Port Addressing menu:

∙[T] Address table size—Defines the number of allowable MAC addresses if the port is secure port enabled. The range can be any value from 1 to 132. The default is 132; it cannot be changed if the port is not secure port enabled.

∙[S] Addressing security—Allows you to enable or disable secure port, which is also known as addressing security.

∙[U] Flood unknown unicast—Allows you to enable or disable flooding of unknown unicasts out all the ports.

∙[M] Flood unregistered multicast—Allows you to enable or disable flooding unregistered multicasts out all the ports.

∙[A] Add a static address—Allows you to add a static unicast hexadecimal MAC address to the table, if the table is not full.

∙[D] Define restricted static address—Allows a source MAC address to be identified, thereby allowing only the device using that MAC address to use the port.

∙[L] List addresses—Displays all the static and dynamic MAC addresses that the switch has learned are attached to the port. The screen displays the first 15 entries beginning with those that have been statically configured.

∙[E] Erase an address—Allows you to remove a statically or dynamically configured MAC address associated with the port.

∙[R] Remove all addresses—Allows you to remove all statically or dynamically configured MAC address associated with the port.

[V]Virtual LAN

To implement VLANs (covered in Chapter 5), use the V command from the Main Menu. Because the Standard Edition software does not support ISL and other high−end VLAN protocols, the VLAN menu is quite simple:

293

Catalyst 2820 − Virtual LAN Configuration

——————————————Action—————————————

[C] Configure VLAN [X] Exit to Main Menu

Enter Selection:

This menu only gives two options. You can choose C to enter another menu that lets you configure a VLAN 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:

Catalyst 2820 − Multicast Registration

Registered multicast addresses: 1

——————————————————Actions——————————————————

[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:
