Cabletron Systems SmartSwitch manual Layer-3 Access Control Lists ACLs

Chapter 18: Security Configuration Guide

Destination secure port: To block access to all file servers on all ports from port et.1.1 use the following command:

filters add secure-port name engineers direction dest vlan 1 in-port-list et.1.1

To allow all engineers access to the engineering servers, you must "punch" a hole through the secure-port wall. A "dest static-entry" overrides a "dest secure port".

filters add static-entry name eng-server dest-mac 080060:abcdef vlan 1 in-port-list et.1.1 out-port-list et.1.2 restriction allow

Layer-3 Access Control Lists (ACLs)

Access Control Lists (ACLs) allow you to restrict Layer-3 traffic going through the SSR. Each ACL consists of one or more rules describing a particular type of IP or IPX traffic. An ACL can be simple, consisting of only one rule, or complicated with many rules. Each rule tells the router to either permit or deny the packet that matches the rule's packet description.

For information about defining and using ACLs on the SSR, see “Access Control List Configuration Guide” on page 255.
