Extended Acl Syntax - Dell PowerConnect B-RX Configuration Manual

The following commands apply ACL 102 to the incoming and outgoing traffic on port 1/2 and to the
incoming traffic on port 4/3.
BigIron RX(config)# int eth 1/2
BigIron RX(config-if-e10000-1/2)# ip access-group 102 in
BigIron RX(config-if-e10000-1/2)# exit
BigIron RX(config)# int eth 4/3
BigIron RX(config-if-e10000-4/3)# ip access-group 102 in
BigIron RX(config)# write memory
Here is another example of an extended ACL.
BigIron RX(config)# access-list 103 deny tcp 209.157.21.0/24 209.157.22.0/24
BigIron RX(config)# access-list 103 deny tcp 209.157.21.0/24 eq ftp
209.157.22.0/24
BigIron RX(config)# access-list 103 deny tcp 209.157.21.0/24 209.157.22.0/24 lt
telnet neq 5
BigIron RX(config)# access-list 103 deny udp any range 5 6 209.157.22.0/24 range
7 8
BigIron RX(config)# access-list 103 permit ip any any
The first entry in this ACL denies TCP traffic from the 209.157.21.x network to the 209.157.22.x
network.
The second entry denies all FTP traffic from the 209.157.21.x network to the 209.157.22.x
network.
The third entry denies TCP traffic from the 209.157.21.x network to the 209.157.22.x network, if
the TCP port number of the traffic is less than the well-known TCP port number for Telnet (23), and
if the TCP port is not equal to 5. Thus, TCP packets whose TCP port numbers are 5 or are greater
than 23 are allowed.
The fourth entry denies UDP packets from any source to the 209.157.22.x network, if the UDP port
number from the source network is 5 or 6 and the destination UDP port is 7 or 8.
The fifth 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 103 to the incoming and outgoing traffic on ports 2/1 and 2/2.
BigIron RX(config)# int eth 2/1
BigIron RX(config-if-e10000-2/1)# ip access-group 103 in
BigIron RX(config-if-e10000-2/1)# exit
BigIron RX(config)# int eth 2/2
BigIron RX(config-if-e10000-2/2)# ip access-group 103 in
BigIron RX(config)# write memory

Extended ACL syntax

This section presents the syntax for creating an extended ACL and for binding the ACL to an
interface. Use the ip access-group command in the interface level to bind the ACL to an interface.
Syntax: [no] access-list <num> deny | permit <ip-protocol>
