Chapter 20: Security Configuration Guide

Destination filter: No one from the engineering group (port et.1.1) should be allowed to access the finance server. All traffic destined to the finance server's MAC will be dropped.

filters add address-filter name finance dest-mac AABBCC:DDEEFF vlan 1 in-port-list et.1.1

Flow filter: Only the consultant is restricted access to one of the finance file servers. Note that port et.1.1 should be operating in flow-bridging mode for this filter to work.

filters add address-filter name consult-to-finance source-mac 001122:334455 dest-mac AABBCC:DDEEFF vlan 1 in-port-list et.1.1

Static Entries Example

Source static entry: The consultant is only allowed to access the engineering file servers on port et.1.2.

filters add static-entry name consultant source-mac 001122:334455 vlan 1 in-port-list et.1.1 out-port-list et.1.2 restriction allow

Destination static entry: Restrict "login multicasts" originating from the engineering segment (port et.1.1) from reaching the finance servers.

filters add static-entry name login-mcasts dest-mac 010000:334455 vlan 1 in-port-list et.1.1 out-port-list et.1.3 restriction disallow

or

filters add static-entry name login-mcasts dest-mac 010000:334455 vlan 1 in-port-list et.1.1 out-port-list et.1.2 restriction allow

Flow static entry: Restrict "login multicasts" originating from the consultant from reaching the finance servers.

filters add static-entry name consult-to-mcasts source-mac 001122:334455 dest-mac 010000:334455 vlan 1 in-port-list et.1.1 out-port-list et.1.3 restriction disallow

Port-to-Address Lock Examples

You have configured some filters for the consultant on port et.1.1 If the consultant plugs his laptop into a different port, he will bypass the filters. To lock him to port et.1.1, use the following command:

filters add port-address-lock name consultant source-mac 001122:334455 vlan 1 in-port-list et.1.1
