Setting Up SNMP Traps for
Windows NT Servers
Windows NT Servers
To configure a Windows NT server to send
SNMP traps to one or more enterprise management consoles, you need to
configure each SNMP service on the server to make sure that:
- The server lists the community
string or community name of the enterprise management console.
- The server lists the enterprise management
console as the recipient of traps from the Windows
NT agents software.
Checking the Community
String
You can use the default community name or
community string of public. However, choosing a community name other than
public provides more security because it limits the communication to only
those computers that have the specified community string.
To set the community string for Windows
NT 4.0:
- In the Control Panel window, double-click
the Network icon, and then click the Services tab if it
is not already selected.
In the Network Services list, scroll to the SNMP service,
click once to select it, and then click Properties.
The Microsoft SNMP Properties window is displayed.
NOTE: If you do not have the SNMP
service installed, you can install it by clicking Add in the
Network window. The Select Network Service window is displayed,
from which you can select SNMP Service. You need to insert the Windows
NT 4.0 CD to enable the computer to copy the necessary files for the
SNMP service.
- Click the Security tab in the Microsoft
SNMP Properties window to display the Security settings.
- Make sure that the community name or community
string that you want to use for the server is specified in the Accepted
Community Names list.
If the name is not already on the list, click Add to display
the SANscape window. Type the new name in the entry field and click
Add in that window. The Security tab is displayed with the new
name on the Accepted Community Names list.
NOTE: Community names or community
strings are case-sensitive.
- (Optional) If desired, change the default
setting of Accept SNMP Packets from Any Host to Only Accept
SNMP Packets from These Hosts and add the network address of the
enterprise management computer that receives the traps from the SANscape
Agent on the server.
Using this setting provides more security because it lets you specify
the computer or computers from which the Windows NT agents accept information.
To add the network address of the computer with SANscape management
console software to the lower list box, click Add to access the Security
Configuration window. Type the IP address in the Entry box and click
Add in that window. The Security tab reappears with the SANscape management
console computers address.
- Click OK.
Specifying
the Trap Recipient
In this procedure, you are
listing the enterprise management console as a recipient of traps from
the server.
NOTE: For the procedure,
you need the IP address of the enterprise management console that receives
the traps. The procedure also requires the same community name as specified
in Setting Up Servers for
Traps.
The steps for specifying
an enterprise management console computer as the recipient of the agent
traps are as follows.
- Click the Traps
tab of the Microsoft SNMP Properties window to display the
Traps settings.
- Make sure the same community
name is specified as the community name that was indicated in the
Security tab earlier.
If you need to correct the community name, type the name in the Community
Name field and click Add. If another name is already in
the entry field, it is retained after you type over it. To remove
a name, select it and click Remove.
- Add the IP address of
the enterprise management console in the Trap Destinations
list.
- Click Add.
The Service Configuration window is displayed.
- Type the IP address
in the Entry field and click Add.
The Traps tab is displayed with the new network address in
the Trap Destinations list.
- Type each IP address
in the following format: AAA.BBB.CCC.DDD
You do not need to type leading zeros. An example of an appropriate
address is: 192.168.100.1
- If you want to send optional
SANscape traps to another enterprise management console, type the
network address of that management workstation.
If you have more than one enterprise management console, each one
needs to have its address indicated here.
- Click OK to confirm
your settings.
- Click Close to
leave the Network window.
- Exit Windows NT and restart
the server.
If you are planning to install SANscape, you do not have to reboot
until after you install the software.
