Configuring Network Devices for Management

After a short overview, this chapter describes how to configure the various devices in the Cisco MGC node. This task is typically done by the system administrator.

Note Take precautions to avoid more than one user simultaneously accessing and modifying the same network device or any of its components. Establish access schedules for all your users.

Overview of Configuration

In Cisco MNM, device configuration means setting up devices that are in the Cisco MGC node to forward alarms ("SNMP traps," from the point of view of the device) to Cisco MNM. For Cisco MNM to be able to receive and manage alarms, the devices must be configured to send them. Configuration involves editing the SNMP configuration file on the device to specify:

•The Cisco MNM management server's IP address as the SNMP trap destination

•Depending on the device, the severity level of traps to be forwarded, the configuration of SNMP community strings, and the SNMP trap source

Note The other task in setting up the management of your network is deploying the network devices, adding them to the Cisco MNM network model. Deployment tells Cisco MNM how to communicate with the managed devices; configuration tells the devices how to communicate with Cisco MNM. Deployment is typically done by users; configuration is typically done by the system administrator. See "Deploying Your Network in Cisco MNM" for details of deployment.

Note For information on configuring trap forwarding from Cisco MNM to northbound management systems, see "Managing Faults with Cisco MNM."

The Cisco MGC host, BAMS, Cisco SLT, and the Cisco LAN Switch are configured by opening a Telnet session with the device and entering the prescribed SNMP configuration settings. You can initiate the Telnet session at the UNIX command prompt, or, if the device has been deployed in Cisco MNM, you can use Cisco MNM to initiate the Telnet session.

Information Needed for Configuration

Have on hand the following information:

•For the Cisco MGC and BAMS, the superuser password.

•For the Cisco SLT and the Cisco LAN switch, the login and enable passwords for the device.

•The IP address of the Cisco MNM server (standalone server or management server in a distributed configuration), to be used as the SNMP trap destination. If multiple IP addresses and host names are configured on your server, choose the IP address that is in the same LAN as the devices.

•For the Cisco SLT and Cisco LAN Switch, the IP address of the device (this is the same address that is entered when the device is deployed in Cisco MNM).

Configuring the Cisco MGC

Use this procedure to configure the Cisco MGC for network management:

Step 1 Access the Cisco MGC in either of the following ways:

•Enter the command:

telnet Cisco-MGC-IP-address

•If the device has been deployed in Cisco MNM, in the Map Viewer, right-click on it and choose Tools > Telnet. A Telnet window opens.

Step 2 Type su - root to become the root user.

You see the password prompt.

Step 3 Enter the super-user password.

Step 4 Type cd /etc/srconf/agt.

Step 5 Use a text editor to edit the snmpd.cnf file.

Step 6 Search for the keyword sysName, and change the system name to the host name of the Cisco MGC. The entry should be:

sysName Cisco-MGC-hostname

Step 7 Add the following line after the existing snmpNotifyEntry lines:

snmpNotifyEntry 33 rambler trap nonVolatile

Note The second field on the line (33 in the example) must be a value that is unique in the snmpNotifyEntry section.

Step 8 Add the following line after the existing snmpTargetAddrEntry lines:

snmpTargetAddrEntry 35 snmpUDPDomain 10.1.1.1:0 100 3 rambler \ v2cExampleParams nonVolatile 255.255.255.255:0 2048

Note The \ character at the end of the first line in the command above indicates that this entire command should be entered on one line.

Note In the example above, the IP address of the Cisco MNM is 10.1.1.1.

Note The second field on the line (34 in the example) must be a value that is unique in the TargetAddrEntry section.

Step 9 Check your typing to verify that you have entered the exact information specified. UNIX is case-sensitive, so make sure that "rambler" is typed in the same case each time it is entered.

Step 10 Save the changes you made to the snmpd.cnf file.

Step 11 Determine the process ID. From the Sun Solaris command line, enter the command:

#ps -ef | grep snmpdm

You see information similar to the following:

root 565 1 0 Mar 20 ? 0:01 /opt/CiscoMGC/bin/snmpdm -d

mgcusr 7463 23729 0 12:33:04 pts/13 0:00 grep snmpdm

The process ID of the snmpdm daemon is the second field on the line that ends with snmpdm -d. In this example, the process ID of the SNMP daemon is 565.

Step 12 Terminate and restart the SNMP daemon. Enter the command:

#kill -9 SNMP-daemon-process-ID

Note The SNMP daemon restarts automatically after termination.

Step 13 Repeat Step 11 to verify that the SNMP daemon restarted.

Configuring the Cisco SLT

Use the following procedure to configure the Cisco SLT for network management:

Step 1 Access the Cisco SLT in either of the following ways:

•Enter the command:

telnet Cisco-SLT-IP-address

•If the device has been deployed in Cisco MNM, in the Map Viewer, right-click on it, and choose Tools > Telnet. A Telnet window opens.

The password prompt displays.

Step 2 Enter the login password for the Cisco SLT.

You see the slt prompt.

Step 3 Enter the command enable.

The password prompt displays.

Step 4 Enter the enable password for the Cisco SLT.

You see the slt prompt.

Step 5 Enter the command configure terminal.

You see the slt(config) prompt.

Step 6 Configure SNMP community strings. For example, to set the read-only community string to public and the read-write community string to private, enter the commands:

snmp-server community public RO

snmp-server community private RW

Step 7 Configure traps to be sent to Cisco MNM.

a. To configure the Cisco SLT to send all types of traps, enter the command:

snmp-server enable traps

b. To configure the Cisco SLT to send traps for all syslog messages with a severity of warnings or worse, enter the command (you can set this severity to the level you want):

logging history warnings

c. To configure the IP address of the Cisco MNM to which traps are sent, enter the command (in this example the IP address of the Cisco MNM is 10.1.1.1):

snmp-server host 10.1.1.1 public

Step 8 Set the SNMP trap source, which specifies the Cisco SLT interface from which traps are sent. The SNMP trap source should be the interface with the IP address that the Cisco MNM is configured to use for SNMP communications.

For example, suppose that the IP address 10.2.2.2 is assigned to interface Ethernet 0/0 on the Cisco SLT. If Cisco MNM is configured to communicate with the Cisco SLT using IP address 10.2.2.2 (the address given when the device is deployed in Cisco MNM), then the trap interface on the Cisco SLT should be Ethernet 0/0. In this example, you would enter the command:

snmp-server trap-source Ethernet0/0

Step 9 Set the maximum SNMP packet size to 2 kB by entering the command:

snmp-server packetsize 2048

Step 10 To exit configuration mode, press Ctrl Z. Then enter the write command to write the configuration to Flash memory.

Configuring the Cisco LAN Switch Catalyst 2900XL

Use the following procedure to configure the Cisco Catalyst 2900XL LAN switch for network management:

Step 1 Access the Cisco LAN Switch in either of the following ways:

•Enter the command:

telnet Cisco-LAN-switch-IP-address

•If the device has been deployed in Cisco MNM, in the Map Viewer, right-click on it and choose Tools > Telnet. A Telnet window opens.

You see the password prompt.

Step 2 Enter the login password for the LAN switch.

You see the 2900xl prompt.

Step 3 Enter the command enable.

You see the password prompt.

Step 4 Enter the enable password for the LAN switch.

You see the 2900xl prompt.

Step 5 Enter the command configure terminal.

You see the 2900xl(config) prompt.

Step 6 Configure SNMP community strings. For example, to set the read-only community string to public and the read-write community string to private, enter the commands:

snmp-server community public RO

snmp-server community private RW

Step 7 Configure traps to be sent to Cisco MNM.

a. To configure the LAN switch to send all types of traps, enter the command:

snmp-server enable traps

b. To configure the IP address of the Cisco MNM to which traps are sent, enter the command (in this example the IP address of the Cisco MNM is 10.1.1.1):

snmp-server host 10.1.1.1 public

Step 8 Set the SNMP trap source, which specifies the LAN switch interface from which traps are sent. The SNMP trap source should be the interface with the IP address that the Cisco MNM is configured to use for SNMP communications.

For example, suppose that the IP address 10.2.2.2 is assigned to interface VLAN1 on the LAN switch. If Cisco MNM is configured to communicate with the LAN switch using IP address 10.2.2.2 (the address given when the device is deployed in Cisco MNM), the trap interface on the LAN switch should be VLAN1. In this example, you would enter the command:

snmp-server trap-source VLAN1

Step 9 Set the maximum SNMP packet size to 2 kB by entering the command:

snmp-server packetsize 2048

Step 10 To exit configuration mode, press Ctrl Z. Then enter the write command to write the configuration to Flash memory.

•Enter the command:

telnet Cisco-LAN-switch-IP-address

•If the device has been deployed in Cisco MNM, in the Map Viewer, right-click on it and choose Tools > Telnet. A Telnet window opens.

You see the password prompt.

Step 2 Enter the login password for the LAN switch.

You see the cat prompt.

Step 3 Enter the command enable.

You see the password prompt.

Step 4 Enter the enable password for the LAN switch.

You see the cat(enable) prompt.

Step 5 Configure SNMP community strings. For example, to set the read-only community string to public and the read-write community string to private, enter the commands:

set snmp-community read-only public

set snmp-community read-write private

Step 6 Configure traps to be sent to Cisco MNM.

a. To configure the LAN switch to send all types of traps, enter the command:

set snmp trap enable

b. To configure the IP address of the Cisco MNM to which traps are sent, enter the command (in this example the IP address of the Cisco MNM is 10.1.1.1):

set snmp trap 10.1.1.1 public

Step 7 To exit enable mode, type exit.

Configuring BAMS

Use the following procedure to configure a BAMS server for network management:

Step 1 Access the BAMS server in either of the following ways:

•Enter the command:

telnet Cisco-BAMS-server-IP-address

•If the device has been deployed in Cisco MNM, in the Map Viewer, right-click on it and choose Tools > Telnet. A Telnet window opens.

Step 2 Type su - root to become the root user.

Step 3 Type cd /etc/srconf/agt.

Step 4 Use a text editor to edit the snmpd.cnf file.

Step 5 Search for the keyword sysName and change the system name to the host name of the BAMS. The entry should be:

sysName BAMS-server-hostname

Step 6 Add the following line after the existing snmpNotifyEntry lines:

snmpNotifyEntry 32 rambler trap nonVolatile

Note The second field on the line (32 in the example) must be a value that is unique in the snmpNotifyEntry section.

Step 7 Add the following line after the existing snmpTargetAddrEntry lines:

snmpTargetAddrEntry 34 snmpUDPDomain 10.1.1.1:0 100 3 rambler \ v2cExampleParams nonVolatile 255.255.255.255:0 2048

Note In the example above, the IP address of the Cisco MNM is 10.1.1.1, and the \ character entered at the end of the first line indicates that the entire command should be entered on one line.

Note The second field on the line (34 in the example) must be a value that is unique in the TargetAddrEntry section.

Step 8 Check your typing to verify that you have entered the exact information specified. UNIX is case-sensitive, so make sure that "rambler" is typed in the same case each time it is entered.

Step 9 Save the changes you made to the snmpd.cnf file.Save the changes you made to the snmpd.cnf file.

Step 10 Determine the process ID. From the Sun Solaris command line, enter the command:

#ps -ef | grep snmpdm

You see information that resembles the following:

root 565 1 0 Mar 20 ? 0:01 /opt/BAMS/bin/snmpdm -d

mgcusr 7463 23729 0 12:33:04 pts/13 0:00 grep snmpdm
