Chapter 1 Controlling CSS Access

Controlling CSS Network Traffic Through Access Control Lists

Table 1-1 ACL Configuration Quick Start

Task and Command Example

1.Enter global configuration mode.

# config (config)#

2.Create an ACL and access ACL mode. Enter an ACL index number from 1 to 99.

(config)# acl 7

Create ACL <7>, [y,n]:y (config-acl[7])#

3.Configure clauses in the ACL. The CSS will use the clauses to control traffic on the circuit on which you will apply the ACL (for example, VLAN1). Enter a clause number from 1 to 254 and define the clause parameters. The syntax for defining a clause is:

clause number permitdenybypass protocol [source_info {source_port}] dest [dest_info {dest_port}] {log} {prefer servicename} {sourcegroup name}

See Table 1-2for information on the clause command options. For example, to block ports 20 to 23 for all user access coming into the CSS on a circuit from outside the network, enter:

(config-acl[7])#clause 10 deny any any destination range 20 23

To permit all other traffic through the CSS on a circuit, enter:

(config-acl[7])#clause 15 permit any any destination any

4.Apply the ACL to a specific circuit. In this example, there is only one VLAN, the default VLAN1. For example, to apply acl 7 to circuit VLAN1, enter:

(config-acl[7])#apply circuit-(VLAN1)

You can also apply ACL 7 to all circuits on the CSS by using the apply all command.
