Configuring extended numbered ACLs
13
The traffic-policy option enables the device to rate limit inbound traffic and to count the packets
and bytes per packet to which ACL permit or deny clauses are applied. For configuration
procedures and examples, refer to Chapter 17, “Configuring Traffic Policies”.
Configuration examples for extended numbered ACLs
To configure an extended access list that blocks all Telnet traffic received on port 1 from IP host
209.157.22.26, enter the following commands.
Here is another example of commands for configuring an extended ACL and applying it to an
interface. These examples show many of the syntax choices. Notice that some of the entries are
configured to generate log entries while other entries are not thus configured.
The first entry permits ICMP traffic from hosts in the 209.157.22.x network to hosts in the
209.157.21.x network.
The second entry denies IGMP traffic from the host device named “rkwong” to the 209.157.21.x
network.
The third entry denies IGMP traffic from the 209.157.21.x network to the host device named
“rkwong”.
The fourth entry denies all IP traffic from host 209.157.21.100to host 209.157.22.1 and generates
Syslog entries for packets that are denied by this entry.
The fifth entry denies all OSPF traffic and generates Syslog entries for denied traffic.
The sixth entry permits all packets that are not explicitly denied by the other entries. Without this
entry, the ACL would deny all incoming or outgoing IP traffic on the ports to which you assign the
ACL.
The following commands apply ACL 102 to the incoming traffic on port 2 and to the incoming traffic
on port 3.
Here is another example of an extended ACL.
PowerConnect(config)# access-list 102 perm icmp 209.157.22.0/24 209.157.21.0/24
PowerConnect(config)# access-list 102 deny igmp host rkwong 209.157.21.0/24 log
PowerConnect(config)# access-list 102 deny igrp 209.157.21.0/24 host rkwong log
PowerConnect(config)# access-list 102 deny ip host 209.157.21.100 host
209.157.22.1 log
PowerConnect(config)# access-list 102 deny ospf any any log
PowerConnect(config)# access-list 102 permit ip any any
