Clearing MAC Addresses

The clear port security command is used to clear the MAC address from a list of secure addresses on a port. If the clear command is executed on a MAC address that is in use by an interface, the MAC address may be relearned by the switch and made secure again if dynamic port security is being used. Dynamic port security is when a switch is configured to allow only the first MAC address used on an interface to use the switch port. If another interface using another MAC address tries to use the switch port, the switch will automatically place the port in the disabled state. The light color on the switch will change from green to amber indicating the port is disabled. Cisco recommends that you disable port security before you clear any MAC addresses. Here is the command and its possible syntaxes, and an example of using the command:

clear port security mod_num/port_num {mac_addrall} Coriolis5000> (enable) clear port security 3/10−20 all

All addresses cleared from secure address list for ports 3/10−20

Coriolis5000> (enable)

Configuring the Catalyst 5000 Supervisor Engine Module

To configure the basic configuration on a Catalyst 5000 Supervisor Engine Module, follow these steps:

1.Access the Cisco Catalyst 5000 through the console port located on the Supervisor Engine 3. The initial password is just pressing the Enter key, as shown here:

Cisco Systems Console

Enter password:

Console> enable

Enter password:

Console>(enable)

2. Configure the hostname:

Console>(enable) set prompt Catalyst5000>

Catalyst5000> (enable)

3.Configure a password for the switch. Press Enter for the old password if none has ever been configured:

Catalyst5000> (enable) set password

Enter old password:

Enter new password: coriolis1

Retype new password: coriolis1

Password changed.
