Step 3: Configure the SNMP subagents
There are several SNMP subagents shipped with z/OS® Communications Server:
- The TCP/IP subagent reports information about the TCP/IP stack. For details on configuring this subagent, see TCP/IP subagent configuration.
- The OMPROUTE subagent reports information specific to OSPF. The ROUTESA_CONFIG statement is used in the OMPROUTE configuration file to configure the OMPROUTE subagent. For details on ROUTESA_CONFIG, see z/OS Communications Server: IP Configuration Reference.
- The Network SLAPM2 subagent reports information about defined policies and performance statistics related to traffic using those policies. For configuration information about the Network SLAPM2 subagent, see Quality of service.
- The TN3270E Telnet subagent reports information about TN3270E Telnet server connections and monitoring values. For information on the TNSACONFIG statement and the parameters needed to start the TN3270E Telnet subagent, see z/OS Communications Server: IP Configuration Reference.
- The OSA-Express® Direct SNMP subagent is also shipped with z/OS CS but is supported by the System z® OSA Support Group. The OSA-Express Direct SNMP subagent and the OSA MIB provided by the System z OSA Support Group can be used with Communications Server SNMP support to provide SNMP management data for some OSA adapters. For details regarding the OSA-Express Direct SNMP subagent and OSA MIB, see zEnterprise System and System z10 OSA-Express Customer's Guide and Reference.
These subagents use the stack's IPv4 primary interface IP address when connecting to the SNMP agent. The IPv4 primary interface IP address is either the first IPv4 IP address specified in the HOME profile statement, or the IP address of the IPv4 interface specified on a PRIMARYINTERFACE profile statement. If the subagents cannot obtain the IPv4 primary interface IP address, they will use the IPv4 loopback IP address, 127.0.0.1, to connect to the agent. For information on using the IPv4 primary interface IP address and a community name to permit the subagents to connect to the SNMP agent, see Provide community name information or Provide community-based and user-based security and notification destination information.
