After ensuring physical connectivity, go to the Application menu and click on Setup New Device…. You see a screen similar to below figure. In our case, we configure IP address If everything goes well, you reach Step 3 — Configuration Summary as shown in the figure below. What we have done so far is to configure IP address Now you should connect the Ethernet port of your computer to interface FastEthernet4 of the router using a crossover Ethernet cable.

We highlight the IP address Cisco CP will not try to connect to the router over the Ethernet interface and if all goes well the Discovery Status should change to Discovered as shown in figure below. At this stage the router is fully set up with Cisco Configuration Professional and we can configure it using easy-to-use wizards by pressing the Configure in the top left area of the display. Some new entries appear in the left pane of the display as shown in Figure We created the same access list earlier in the chapter using command-line interface CLI.

In this dialogue box you supply a name and specify that it is an extended ACL, and then press Add to create the first access list statement. We now creat the first access list statement as shown in Figure and press OK to proceed. The access list has been created by now as shown in Figure , and we need to apply it to an interface. Press Associate to proceed. The configuration is complete and you return to the Add a Rule dialogue box, as shown in Figure Simply press OK to proceed.

Another box appears that displays configuration that would actually be applied to the router, as shown in Figure You can see that the configuration that actually gets applied to the router is just the same we created in an earlier section of the chapter. Press Deliver to apply the configuration to the running configuration.

Command delivery status looks good, as shown in Figure This table further explains the concept. Based on the binary mask, you can see that the first three sets octets must match the given binary network address exactly The last set of numbers are "don't cares". Therefore, all traffic that begins with Therefore, with this mask, network addresses Subtract the normal mask from In this example, the inverse mask is determined for network address Note: Subnet masks can also be represented as a fixed length notation.

For example, This list describes how to summarize a range of networks into a single network for ACL optimization. Consider these networks. The first two octets and the last octet are the same for each network. This table is an explanation of how to summarize these into a single network. The third octet for the previous networks can be written as seen in this table, according to the octet bit position and address value for each bit. Since the first five bits match, the previous eight networks can be summarized into one network All eight possible combinations of the three low-order bits are relevant for the network ranges in question.

This command defines an ACL that permits this network. If you subtract This table is an explanation of how to summarize these. Unlike the previous example, you cannot summarize these networks into a single network. If they are summarized to a single network, they become This summarized network Among these, In order to cover the specific networks in question, you need a minimum of two summarized networks.

The given four networks can be summarized into these two networks:. For networks Traffic that comes into the router is compared to ACL entries based on the order that the entries occur in the router. New statements are added to the end of the list. The router continues to look until it has a match. If no matches are found when the router reaches the end of the list, the traffic is denied. For this reason, you should have the frequently hit entries at the top of the list.

There is an implied deny for traffic that is not permitted. A single-entry ACL with only one deny entry has the effect of denying all traffic. You must have at least one permit statement in an ACL or all traffic is blocked.

These two ACLs and have the same effect. In this example, the last entry is sufficient. A good source of information for well-known ports is RFC The router can display descriptive text on some of the well-known ports. Use a? During configuration, the router also converts numeric values to more user-friendly values.

This is an example where you type the ICMP message type number and it causes the router to convert the number to a name. You can define ACLs without applying them. But, the ACLs have no effect until they are applied to the interface of the router.

It is a good practice to apply the ACL on the interface closest to the source of the traffic. As shown in this example, when you try to block traffic from source to destination, you can apply an inbound ACL to E0 on router A instead of an outbound list to E1 on router C. An access-list has a deny ip any any implicitly at the end of any access-list. Note that the source IP address is 0.

Source port is 68 and destination Hence, you should permit this kind of traffic in your access-list else the traffic is dropped due to implicit deny at the end of the statement. The router uses the terms in, out, source, and destination as references. Traffic on the router can be compared to traffic on the highway. If you were a law enforcement officer in Pennsylvania and wanted to stop a truck going from Maryland to New York, the source of the truck is Maryland and the destination of the truck is New York.

The roadblock could be applied at the Pennsylvania—New York border out or the Maryland—Pennsylvania border in. Out —Traffic that has already been through the router and leaves the interface. The source is where it has been, on the other side of the router, and the destination is where it goes.

In —Traffic that arrives on the interface and then goes through the router. The source is where it has been and the destination is where it goes, on the other side of the router. Inbound —If the access list is inbound, when the router receives a packet, the Cisco IOS software checks the criteria statements of the access list for a match.

If the packet is permitted, the software continues to process the packet. If the packet is denied, the software discards the packet. Outbound —If the access list is outbound, after the software receives and routes a packet to the outbound interface, the software checks the criteria statements of the access list for a match. If the packet is permitted, the software transmits the packet. The in ACL has a source on a segment of the interface to which it is applied and a destination off of any other interface.

The out ACL has a source on a segment of any interface other than the interface to which it is applied and a destination off of the interface to which it is applied. When you edit an ACL, it requires special attention. For example, if you intend to delete a specific line from a numbered ACL that exists as shown here, the entire ACL is deleted.

Then make any changes and copy the configuration back to the router. This is a sample of the configuration:. Issue the show access-list command in order to view the ACL entries. The sequence numbers such as 10, 20, and 30 also appear here.

In the show access-list command output, the sequence number 5 ACL is added as the first entry to the access-list The major difference in a standard access list is that the Cisco IOS adds an entry by descending order of the IP address, not on a sequence number. This example shows the different entries, for example, how to permit an IP address This entry is added in the top of the list in order to give priority to the specific IP address rather than network.

If you add to an existing access-list configuration, there is no need to remove the crypto map. If you add to them directly without the removal of the crypto map, then that is supported and acceptable. If you need to modify or delete access-list entry from an existing access-lists, then you must remove the crypto map from the interface.

After you remove crypto map, make all changes to the access-list and re-add the crypto map. If you make changes such as the deletion of the access-list without the removal of the crypto map, this is not supported and can result in unpredictable behavior.

Go into configuration mode and enter no in front of the access-group command, as shown in this example, in order to remove an ACL from an interface.

The dashboard provides a single-pane view of the switch. The user can monitor the connected and error ports, the health of the switch, Power over Ethernet PoE available, critical alerts on the switch, etc. Language support: The user interface can be converted to easily support other languages. Current language support: English default , Mandarin, Japanese, and Korean. Opens a guide to explain the features being configured on the switch.

Displays the version of Cisco Configuration Professional running on the switch. Displays the latest system logs from the switch. Clicking this icon will save the current configuration of the switch to the startup configuration. Switch view: Dynamic display of switch ports and their status for each switch, along with display of its hostname, serial number, and MAC address.

In the case of a stack, details about the role of each switch, such as primary or stack member details, are displayed. System messages: Displays the critical switch logs. Only the Critical, Alerts, and Emergency logs are displayed here. The logs are color-coded to show the level of the log.

Navigation pane: The pane is a tree design with two levels of branching. Dashboard: A single-page view of the switch health. Ports: Displays all the port statistics. The error counters on the individual and bundled ports are displayed on this page. Clients: Gives a snapshot view of the end devices connected to the switch and also provides details such as:. This list can be exported as a spreadsheet and saved for auditing purposes.

Other switch-level settings such as physical stacking, virtual stacking parameters, spanning tree, VLAN Trunking Protocol, and Bluetooth can be configured here. Troubleshooting: Basic troubleshooting, such as connectivity of devices from the switch, can be performed by using ping or traceroute. Device health checks can be performed by running diagnostics. The user can also erase switch configurations or reload the switch stack or individual switch.

NetFlow: Allows configuration of the switch to export details of the packets sent to the switch on different ports. Static routing: Through this page, users can create new static routes or modify or delete existing routes on supported platforms. ACL: Access control lists can be configured through this page, allowing the administrator to limit network traffic and restrict network access to certain users and devices.

Software update: Provides administrators an option to upgrade the Cisco Configuration Professional version or the switch Cisco IOS version remotely through the local system. System: Various time-related settings, such as setting the time zone and adding a Network Time Protocol NTP server can be done through this page. User Administration: Allows administrators to control access to the switch by setting up new users and their privilege levels, modifying the password or privilege level of existing users, and deleting users altogether.

Switch information: Dashlets displaying critical real-time system information such as CPU and memory utilization, system temperature and power consumption. The dashboard is refreshed every 60 seconds with updated data. They can also be set manually. Once an NTP server is added, the user can check the synchronization status on the same page. A user can also set the system time manually on the switch, along with advanced options such as setting the time zone and enabling daylight savings.

Basic attributes of the switch, such as the hostname, default gateway or route, system MTU, and switch management IP address can be configured on this page. The input ranges are also explained. Note: The dongle name shows up with the last four characters of the MAC address.

Method Status Protocol. Bluetooth0 An uplinks can be configured as a trunk interface Layer 2 port or can be assigned an IP address Layer 3 port. A user can also easily configure the port as a routed port by toggling the port mode.

On the same page, Cisco Configuration Professional allows users to configure multiple ports at once. To configure multiple ports at once, select multiple ports in the switch view to select multiple ports in Windows, Ctrl-click; on a Mac, Command-click. Note: When multiple interfaces are selected, the old port configurations of the individual ports are erased.

This list can also be exported to a spreadsheet for easy documentation. Different kinds of end clients can connect to the switch, such as IP phones, PCs, cameras, access points, VM servers, printers, point-of-sale devices, etc. Cisco Configuration Professional provides ways to easily monitor and manage clients connected.

If the end client is drawing power from the switch to boot up, the port clearly indicates the amount of power being drawn. When PCs and laptops are connected to the IP phone port, which in turn is connected to the switch port, it is best practice is to segregate the voice traffic from the IP phone and the data traffic from the PC. Any preexisting configurations on the ports selected will be erased. When connecting VM server ports or access points that carry WLAN traffic to the switch, the switch port will need to be configured as a trunk.

See all of the ACLs that are configured on the controller by entering this command:. The Counter text box increments each time a packet matches an ACL rule, and the DenyCounter text box increments each time a packet does not match any of the rules. When you try to create an interface name with space, the controller CLI does not create an interface. For example, if you want to create an interface name int 3, the CLI will not create this since there is a space between int and 3.

Configure an ACL rule by entering config [ipv6] acl rule command:. Save your changes by entering this command:. You can configure rules for Layer 2 access control lists ACLs based on the Ethertype associated with the packets. This is applicable only for locally-switched WLANs. Fast-Path looks into the Ethernet headers associated with the packets and forwards the packets whose Ethertype matches with the one that is configured for the ACL.

The AP forwarding plane looks into the Ethernet headers associated with the packets and forwards or denies the packets based on the action whose Ethertype matches with the one that is configured for the ACL. Controllers configured to preform Central Switching and Centralized Authentication displays the name of the Layer-2 ACL being applied to roaming users incorrectly.

The situation occurs when an authorized device preforms a Layer-3 roam from the anchor controller to a foreign controller. After roaming, if an administrator issues the show acl layer2 summary command on the CLI of the foreign controller the incorrect information is displayed.

It is expected that the ACL applied by the anchor will follow the authenticated client as it roams from controller to controller. This command is applicable for all types of ACLs. In an HA environment, the counters are not synchronized between the active and standby controllers.

The controller supports up to 16 rules for each ACL. In the Sequence text box, enter a value between 1 and 16 to determine the order of this rule in relation to any other rules defined for this ACL. If rules 1 through 4 are already defined and you add rule 15, it is added as rule 5.

If you add or change a sequence number for a rule, the sequence numbers for other rules adjust to maintain a continuous sequence. From the Ether Type drop-down list, choose any option from the following Ether type:. When using these devices, you can set pre-authentication ACLs on the controller to determine where devices have the right to go. In Release 8. Specifies to create ACL. Specifies to add a new URL domain for the access control list. URL domain name should be given in a valid format, for example, Cisco.

The hostname comparison is a sub string matched wildcard based. You must use the ACL name that you have created already. Specifies to delete an existing URL domain for the access control list. If you want to see if packets are hitting any of the ACLs configured on your controller, check the Enable Counters check box and click Apply.

The URL domain name should be given in a valid format, for example, Cisco. URL filtering feature allows you to control access to websites. It does so by permitting or denying access to specific websites based on information contained in a URL access control list ACL. Controllers support up to 64 ACLs. To create or delete access control lists in an WLAN. To have seamless access to websites which use different port number instead of default port 80, you will need to create a rule which includes the port number in URL-name:Port format.

Example: Enter the URL as website. Enter the Match Role String in the text box. The interface page for the selected interface appears. Choose the Advanced tab. Choose the Policy-Mapping tab. Enter the Priority Index value. Choose the local policy from the Local Policy drop-down list. Click Add. Hover the mouse cursor over the blue drop-down arrow for that local policy. Choose Remove. Click OK. Mapping the policy to an AP Group in the network. Choose the AP Group. Choose the WLANs tab.

Configure the URL based Filtering feature by entering this command:. Configure an acl to an interface by entering this command:. Create or delete a ACL by entering this command:. Configure the URL address in a valid format example: www. Configure the action of the rule by entering this command:. Example: enter the URL as website.

View the details of a policy by entering this command:. View client details by MAC address by entering this command:. View the WLAN configuration details by entering this command:. View the interface details by entering this command:. Clear the counters by entering this command:. You can troubleshoot the URL Filtering feature by entering these commands:.

The dataplane options available are 0, 1, All. Choose Enable from the Support for CoA drop-down list. Choose Web Policy from the Layer 3 Security drop-down list. This feature allows you to control access to websites by permitting or denying access to websites using DNS-based access control list ACL. These ACLs are configured to either permit or deny traffic based on allowed list or blocked list on any protocol.

Hence when a URL request is blocked, access is denied regardless of the protocol. An ACL can either be an allowed list permit or a blocked list deny. Rules with an independent permit or deny settings are not supported within an ACL. Direct IP address access is blocked in the allowed list. However, it is not blocked in the blocked list.

Action—Select Permit or Deny. To have seamless access to websites which use a different port number instead of the default port 80, create a rule which includes the port number in URL-name: Port format. Configure the external server to the redirect the web page requests by entering this command:. Skip to content Skip to search Skip to footer. Book Contents Book Contents.

Find Matches in This Book. Log in to Save Content. PDF - Complete Book Updated: March 28, Chapter: Access Control Lists. When high priority for an ACL is enabled, two types of rules are possible as follows: Deny : If you add the Deny rule, all the relevant services under the rule are blocked or disabled. Step 2 If you want to see if packets are hitting any of the ACLs configured on your controller, select the Enable Counters check box and click Apply. Step 5 Choose the ACL type.

Step 6 Click Apply. Note If rules 1 through 4 are already defined and you add rule 29, it is added as rule 5. From the Source drop-down list, choose one of these options to specify the source of the packets to which this ACL applies: Any —Any source this is the default value. From the Destination drop-down list, choose one of these options to specify the destination of the packets to which this ACL applies: Any —Any destination this is the default value. Other types of packets such as ARP packets cannot be specified.

The Deny Counters fields shows the number of times that packets have matched the explicit deny ACL rule. Step 9 Click Save Configuration to save your changes. Step 10 Repeat this procedure to add any additional ACLs. Step 2 Click the name of the desired interface. Step 4 Click Save Configuration to save your changes. Step 6 Click Apply to commit your changes. Step 7 Click Save Configuration to save your changes. Step 5 Click Apply. Step 6 Click Save Configuration. Step 4 Select the Web Policy check box.

Bluetooth0 An uplinks can be configured as a trunk interface Layer 2 port or can be assigned an IP address Layer 3 port. All other traffic will be permitted from inside.

Usually the servers which are publicly accessible from the Internet are placed in a DMZ security zone not in the internal protected zone. In the example below, we have a webserver with IP Although the webserver is placed in a DMZ zone, the access-list is applied to the outside interface of the ASA because this is where the traffic comes in. This means that if the Webserver has a private IP configured on its network card e.

Assume we have 4 Web servers in a DMZ zone and we want to allow access to those servers from the Internet. Then we can use this object group in the ACL instead of using each host individually. The advantage of using object groups for both network hosts and service ports is that you can just add or remove entries within the object group without having to change anything on the ACL. For both inbound and outbound access control lists, the IP addresses specified in the ACL depend on the interface where the ACL is applied as discussed before.

For ASA version after 8. For example, assume an inside host with private address This is shown in the figure below. Similarly, a scenario with inbound traffic outside to inside works again the same way. For ASA 8.

For example, assume we have a Web Server located on the inside network should be on a DMZ for better security but for the sake of simplicity we assume it is located on the inside network. The private address configured on the Web Server is Inbound traffic coming from the Internet towards the public address of the Web Server will first go through an ACL to verify if the traffic is permitted or not.

For Cisco ASA version 8. Just to summarize all the above:. Your email address will not be published. This site uses Akismet to reduce spam.
