Configuring Filtering on an Ethernet Interface

To configure protocol filtering for IP only, follow these steps:

1.To configure protocol filtering on the Ethernet, Fast Ethernet, or Gigabit Ethernet ports, you must first enable protocol filtering on the switch. To enable protocol filtering, use this command in Privileged mode:

Coriolis5002 (enable) set protocolfilter enable

2. Configure port 2 on module 2 to filter all traffic unless it is IP based:

Coriolis5002(enable) set port protocol 2/2 ip on

IP protocol set to on mode on module 2/2.

Coriolis5002>(enable)

3. Do the same for port 3 on module 2:

Coriolis5002>(enable) set port protocol 2/3 ip on

IP protocol set to on mode on module 2/3.

Coriolis5002>(enable)

Configuring Port Security on an Ethernet Module

To enable port security on a switch interface, use the following steps:

1. Enable port security on the desired ports. Optionally, you can specify the secure MAC address:

set port security mod_num/port_num {enabledisable} [mac_address]

2. Add MAC addresses to the list of secure addresses:

set port security module number/port number mac_address

Here’s an example of using this command:

Catalyst5000>		(enable)	set port security 2/3 enable
Port 2/3 port		security	enabled with the learned mac address.
Trunking disabled for Port 2/1 due to Security Mode
Catalyst5000>		(enable)	show port 2/1
