About the management station 14-10 Configuring the SNMP Agent 2. Click Add to add the community to the list (or OK if you are modifying a community) and return to the Configuration tab. Defining a trap destination The Trap Destination window enables you to define a new host or to modify an existing host in the Trap Destination list. The hosts in this list will receive traps issued by the Sidewinder G2. Follow the steps below. About the management station 1. In the Host Name or Address field, type the name or IP address of the host you want added to the Trap Destinations list. 2. [Optional] In the Community name field, type the community name associated with this host. 3. Click Add to add the trap destination to the list (or OK if you are modifying a trap destination) and return to the Configuration tab. Enabling/disabling the SNMP server Perform the following steps to enable or disable the SNMP server. 1. In the Admin Console select Services Configuration -> Servers. 2. Select snmpd from the list of server names, and then click the Control tab. 3. Select the burb for which the SNMP agent will be enabled or disabled. The SNMP agent can only be enabled for one burb, and it cannot be enabled for the Firewall burb. 4. Click the Save icon. Note: You must define an allow all rule for the SNMP agent before SNMP queries will be allowed through the Sidewinder G2. For information on creating rules, see “Creating proxy rules” on page 7-4. Note: Enabling the SNMP server will cause the Sidewinder G2 to send a ColdStart trap to the management station(s). The administrator of the SNMP management station should be made aware of the following in order to retrieve information from the Sidewinder G2 SNMP agent:
Communication with systems in an external network Communication with systems in an external network Sidewinder G2 host name or IP address This is needed to set up communication with the Sidewinder G2. Note 1: If the burb in which the SNMP agent is running contains more than one interface, specify the address of the first interface in the burb. The SNMP agent will only respond to the first interface in the burb. Note 2: If you are using High Availability (HA), specify the shared HA cluster IP address or host name, not the actual interface address or host name. Community names configured in the Sidewinder G2 SNMP agent This is needed to allow the management station to retrieve MIB objects from the SNMP agent. MIB information This may be needed to properly translate the object identifications. Be sure to inform the administrator that the Sidewinder G2 supports the Host Resources MIB. Important: On the Sidewinder G2, all Secure Computing Corporation MIB files are located in the /etc/sidewinder/snmp directory. If for some reason these files cannot be accessed from the Sidewinder G2, they can be downloaded via an FTP client or Web browser. The MIB files are scc-mib and scc-sw-mib. To retrieve the files using anonymous FTP, use an FTP client and log in to ftp.securecomputing.com. The directory where the files are located is /pub/mibs. To retrieve the files using a Web browser, point the browser to ftp://ftp.securecomputing.com/pub/mibs/. You can route (or forward) SNMP messages between a management station behind the Sidewinder G2 and any SNMP managed node on the other side of the Sidewinder G2. You can also allow an external management station to access the Sidewinder G2 SNMP agent. Both of these scenarios require the use of a UDP proxy. Important: A UDP proxy is not needed to allow the Sidewinder G2 SNMP agent to communicate with a management station in an internal network (behind the Sidewinder G2). Figure 14-5 summarizes which SNMP configurations require you to configure a UDP proxy. Configuring the SNMP Agent 14-11
