You can query the SNMP agent to collect the sysgroup information and to send configured SNMP alerts to the configured host names or IP addresses.
Note: If you plan to configure Simple Network Management
Protocol (SNMP) traps on the management module, you must install and
compile the management information base (MIB) on your SNMP manager.
The MIB supports SNMP traps. The MIB is included in the management-module
firmware update package that you downloaded from http://www.ibm.com/systems/support/.
To configure SNMP, complete the following
steps:
- Log in to the management module on which you want to configure SNMP. For more information, see Starting the management-module web interface.
- In the navigation pane, click MM Control
→ General Settings. In the management-module information page
that opens, specify the following information:
- Name: The name that you want to use to identify the management module. The name is included with email and SNMP alert notifications to identify the source of the alert. If more than one management module is installed in a BladeCenter unit, each management module can be given a unique name.
- Contact: The name and phone number of the person to contact if there is a problem with the BladeCenter® unit.
- Location: Sufficient detail to quickly locate the BladeCenter unit for maintenance or other purposes.
- Scroll to the bottom of the page and click Save.
- In the navigation pane, click MM Control
→ Network Protocols; then, click the Simple Network Management
Protocol (SNMP) link. A page similar to the one in the following
illustration is displayed.
- Select Enabled in the applicable
SNMP agent fields and in the SNMP traps field to forward alerts
to SNMP communities and users on your network. For you to enable an
SNMP agent, the following criteria must be met:
- System contacts must be specified on the General Settings page.
- The system location must be specified on the General Settings page.
- For SNMPv1, at least one community name must be specified, with
an access type set for each community name:
- Get: All hosts in the community can query MIB objects and receive traps.
- Set: All hosts in the community can query and set MIB objects and receive traps.
- Trap: All hosts in the community can receive traps.
- At least one valid IP address or host name (if DNS is enabled) must be specified for each community.
- For SNMPv3, each SNMPv3 user must be configured.
Note: Alert recipients whose notification method is SNMP will not receive alerts unless both the SNMP agent and the SNMP traps are enabled. - If
you are enabling the SNMPv1 agent, complete the following steps to
set up a community that defines the administrative relationship between
SNMP agents and SNMP managers; otherwise, continue with step 7.
You must define at least one SNMPv1 community. Each community definition
consists of the following parameters:
- Community name
- Host name or IP address
If either of these parameters is not correct, SNMP management access is not granted.
Notes:- If an error message window opens, make the necessary adjustments to the fields that are listed in the error window; then, scroll to the bottom of the page and click Save to save the corrected information. You must configure at least one community to enable the SNMP agent.
- You can have one wildcard IP address with 0.0.0.0 (for IPv4) or 0::0 (for IPv6) in the first position of the first community, with the access type selected as SET. This community address supports GET and SET operations from any IP address. The remaining eight community addresses enable specific IP or host addresses to specify a receiver of traps.
- In the Community Name field, enter a name or authentication string to specify the community.
- Select the Access Type for the community.
- In the corresponding Host Name or IP Address field, enter the host name or IP address of each community manager.
- Complete
one of the following steps, based on DNS server availability:
- If a DNS server is not available on your network, scroll to the bottom of the page and click Save.
- If a DNS server is available on your
network, scroll to the
Domain
Name System (DNS) section. A page similar to the one in the following
illustration is displayed.
- If a DNS server (or servers) is available on your network, select Enabled in the DNS field. The DNS field specifies whether you use a DNS server on your network to translate host names into IP addresses.
- (Optional) If you enabled DNS and IPv6 addressing is enabled, use the Preferred DNS Servers field to select which IP addresses to use first when both IPv6 and IPv4 IP addresses are specified for the DNS servers (IPv6 is the default setting).
- (Optional) If you enabled DNS, select the Send DDNS updates to these servers checkbox to send DNS information to the dynamic domain name servers (DDNS).
- (Optional) If you enabled DNS, in the DNS server IP address fields, specify the IP addresses of up to three DNS servers each for IPv4 and IPv6 on your network.
- Scroll to the bottom of the page and click Save.
- If you are enabling the SNMPv3
agent, complete the following steps to configure the SNMPv3 profile
for each SNMPv3 user; otherwise, configuration is complete.
- Click the Login Profiles link in the Simple Network Management Protocol (SNMP) section or, in the navigation pane, click MM Control → Login Profiles.
- Select
the user that is to be configured; then, click the Configure SNMPv3
User link at the bottom of the Login Profile page. A page similar
to the one in the following illustration is displayed.
- Specify the SNMPv3 configuration
information for this user; then, click Save. Note: If the security settings require passwords, the SNMPv3 Authentication Protocol cannot be set to None if the user has an Access Type of Get or Set. This means that when passwords are required, a user can receive SNMP traps only when the SNMPv3 Authentication Protocol is set to None.
- Repeat step 13.b and step 13.c for each SNMPv3 user.
