The help output shows that 0 is the only option available. To verify these settings, select a module and click Edit Module. If configuration files were previously saved on the router and switch, initialize and reload these devices back to their default configurations. (Cisco Secure ACS includes this detail in its logs. To learn more about the reporting IP address, its role, and dependencies, see Understanding Access IP, Reporting IP, and Interface Settings, page 2-8. In addition, MARS can discover settings, such as network address translations, attached networks, and active access rules, that improve the accuracy of false positive identification, attack path analysis, and L3 network discovery. For more information on determining the access type, see Selecting the Access Type, page 2-10. (The term lines is actually reminiscent of very old technologies so do not worry about why they are called such). These logs relate the authorization communications between clients and the posture validation servers. To configure the supervisor SNMP server and enabled SNMP traps on the Catalyst switch, follow these steps: Step 2 Set the SNMP read community string as follows: Step 3 Set the SNMP write community string as follows: Step 4 To collect RMON Ethernet statistics, RMON data collection must be enabled in the CatOS agent (this is not required in Native IOS). When using telnet or ssh to connect to the IOS, you cannot enter the enable mode if an enable secret or password has not been configured. Step 6 If you entered an address in the Access IP field, select TELNET, SSH, or FTP from the Access Type list, and continue with the procedure that matches your selection: Result: MARS monitors the module for anomalous consumption of resources, such as memory and CPU. a. The steps to setting up a Cisco Router or a switch including configuration and verification/testing are as follows: Connect Pc to router by using console cable. Result: If the username and password are correct and the MARS Appliance is configured as an administrative host for the module, the "Discovery is done." Telnet lines are called vty lines because they are virtual unlike console and auxiliary. Student Name: Carolyn Venable AXIA COLLEGE IT/242 INTRO INTO WAN TECHNOLOGIES Instructor’s Name: Mark Burke Date: July 30, 2011 Router and Switch Configuration The vital components in networking are the routers and switches by plugging the devices installing the routers and switches … Step 6 If you entered an address in the Access IP field, select SNMP from the Access Type list. STP, which is enabled by default on Cisco Switches, should remain enabled, as it is required for L2 mitigation. Connect the Switch to PuTTY. This chapter describes how to bootstrap routers and switches and add those reporting devices and mitigation devices to MARS. NAC Phase II enables Cisco switches to act as network access devices. Learn how to configure and manage a Cisco Switch step by step with this basic switch commands and configuration … … The configuration of the switch varies between these two operating system, as does the addition of the device in MARS. The most basic thing you can do is change the router password from its default to something more secure and unique. Setting up a Wireless Network: Check your Internet settings. These features are not critical to the functions of the router in a network, but these features help make administrating the router easier and secure. This section contains the following topics: When you perform a discovery operation on a base module, MARS lists the discovered modules. Step 10 To add this device to the MARS database, click Submit. dialog box appears when the discovery operation completes. This access allows MARS to retrieve XML files that contain the events generated by the IOS IPS feature. To support this new feature, you must configure the Cisco switch to initiate 802.1x authentication when the link state changes from down to up and periodically if the port remains up but unauthenticated. To enable configuration discovery using FTP access, you must place a copy the Cisco router's or switch's configuration file on an FTP server to which the MARS Appliance has access. After reaching the CLI prompt, a user is at the user exec mode where they cannot even view the configuration. You can add any L2 or L3 device to the MARS as long as SNMP is enabled on the device. Step 2 Select one of the following options from the Device Type list: Step 3 Enter the name of the device in the Device Name field. This diagram illustrates a direct connection without a router or … Cisco routers provide data about the network and its activities in the form of syslog messages and SNMP RO MIBs. b. Enter the corresponding password in the Password field. Result: The IOS IPS Information page appears. •If the switch is running Cisco IOS 12.2 or later, select one of the following options from the Device Type list: Step 9 (Optional) If you defined an access IP and selected and configured an access type, click Discover to determine the device settings. Note IOS IPS does not refer to an IPS module. To prevent this, the passwords can be encrypted using the service password-encryption command in the global configuration mode. Configure router host name such as Router (config) #hostname Configure interface and assign IP address such as Router (config … To be able to view or edit the configuration, the user needs to go to the privileged exec mode using the enable command. GfgSwitch#clock set … From this list, you can select the modules to monitor using MARS. No unauthorized access.$. Any events published by the device to MARS before activation can be queried using the reporting IP address of the device as a match criterion. The system will ask whether you want … Part 2: Configure Devices and Verify Connectivity In … •Network access device logs. For devices that cannot be discovered, such as Windows and Linux hosts and host applications, MARS uses the provided value. •SNMP traffic. Any events published by the device or its modules to MARS before activation can be queried using the reporting IP address of the device or module as a match criterion. •Access lists or NAT statements. The syslog messages provide information about activities on the network, including accepted and rejected sessions. STEP2: Set up a hostname for the particular switch to distinguish it in the network. Cisco routers and switches that are running Cisco IOS Software release 12.2 and later can be configured to provide different types of data to MARS: •Syslog messages. This feature ensures that MARS receives reliable data and identifies the port number of the 802.1x supplicant. For instructions on performing these two steps, refer to the following topics: •Add and Configure a Cisco Switch in MARS. From this mode you can only see some statistic information. To enable SDEE protocol on the Cisco IOS device that supports IOS IPS, follow these steps: Step 1 Log in to the Cisco IOS device using the enable password. 6. Such discussions are provided in Configuring Firewall Devices, page 5-1, and Configuring Network-based IDS and IPS Devices, page 7-1. Enable secret is encrypted before being stored in the config while the enable password is stored as plain text. Before you add a Cisco router to MARS, make sure that you have enabled SNMP, Telnet, SSH, or FTP access to the router. The following topics describe how to configure these settings: To send syslog messages to the MARS Appliance from a device running Cisco IOS Software Release 12.2 and later, follow these steps: Step 1 Log in to the Cisco IOS device with enabled password. One final thing you need to know about passwords is that the line passwords and the enable password is stored in the configuration as plain text. They need not have the same configuration. Resource utilization statistics are also used to generate reports. You must copy the running configuration from the Cisco router or switch. A configuration management tool is a router configuration software that can be used to: Download configurations from Cisco routers and switches; Compare date-based configurations of Cisco routers and switches; Upload configurations to Cisco routers and switches; View and make changes to running router & switch … You must use an FTP server. c. In the Port field, verify the port used for SDEE communications with this device. Step 4 Set the SNMP write community string as follows: The Add and Configure a Cisco Router in MARS procedure provides instructions for configuring the MARS Appliance to discover configuration and settings using these strings. To configure the SNMP RO string settings, follow these steps: Step 2 Enter the configure terminal command to enter configuration mode: Step 3 Set the SNMP read community string as follows: Note This information is required to retrieve the MAC addresses and associated L2 information. 3. 4. You must enable administrative access by the MARS Appliance to any Cisco routers or switches running Cisco IOS Software release 12.2 and later. However, a best practice for basic switch configuration is to change the management VLAN to a VLAN other than VLAN 1. Router is used by LAN as well as MAN. Hence it is essential to secure access to your network devices. Remember that all of the commands in this section work on routers as well as switches. Enable Administrative Access to Devices Running Cisco IOS 12.2 and Later, Configure the Device Running Cisco IOS 12.2 and Later to Generate Required Data, Enable Communications Between Devices Running CatOS and MARS, Configure the Device Running CatOS to Generate Required Data, Configure ExtremeWare to Generate the Required Data, Add and Configure an ExtremeWare Switch in MARS, Add and Configure a Generic Router in MARS. After the base module is defined in the web interface, you can discover the modules that are installed in the switch (click Add Available Module) or add them manually (click Add Module). Second you will need to specify the line number that you want to configure. MARS also uses the MIB to identify trunks to other switches, which are used to populate VLAN information used in L2 path calculations. For more information, see Configuring Resource Usage Data, page 2-42. Step 7 (Optional) To enable MARS to retrieve MIB objects for this reporting device, enter the device's read-only community string in the SNMP RO Community field. Step 6 To add these modules to the base module defined in the MARS database, click Submit. 5. Here I’m explaining how to configure this specific setup. Some people prefer to create also local user accounts (usernames and passwords) on the router itself in order to authenticate to the device. To generate those keys, you must first set the hostname and domain name of the device and then use the crypto key command as shown below: If you leave out the telnet option from the above command, only SSH will be allowed to the device. A malicious user who gets access to these devices can cause network wide problems such as theft of data, loss of connectivity and more. First, you must configure the MARS Appliance as an IP address that is permited to access the switch. A home network with a switch must designate one computer as the gateway to the Internet, and that device must possess two network adapters for sharing, one for the home LAN and one for the Internet WAN.
