Configuring TCP/IP Request/Response Connections
Configuring TCP/IP Request/Response
Connections
The TCP/IP process handling the communication between the SNMP agent process
and SNMP managers is represented by a request/response connection definition. You
specify and request information about the request/response connections by issuing:
•
SCF commands against ENDPOINT objects.
•
SNMP Set requests against the SNMP agent’s zagInEndpointTable entry objects,
as described in Section 3, MIBs Supported by the SNMP Agent.
A TCP/IP request/response connection definition has the following attributes:
•
You name the object when you define it.
•
HOSTADDR or zagInEpHostAddr is the Internet address by which the SNMP
agent can be addressed. The Internet address is the TCP/IP subnet address
through which the SNMP agent receives requests from SNMP managers.
•
NETWORK or zagInEpNetwork is the TCP/IP process that handles
request/response messages.
The default TCP/IP request/response connection definition specifies that the SNMP
agent receives SNMP requests and returns responses through any available subnet
associated with TCP/IP process $ZTC0 on the node on which the agent process is
running.
You can specify that a different TCP/IP process be used in the default configuration by
including a TCPIP^PROCESS^NAME startup parameter in the RUN command when
you start the SNMP agent process.
Using the default request/response connection definition or passing a TCP/IP process
name at startup works for an SNMP agent process that is not sharing the same TCP/IP
subsystem with other SNMP agent processes. However, when multiple SNMP agent
processes use the same TCP/IP subsystem to communicate with SNMP managers,
you must ensure that each SNMP agent process has a distinct subnet available for its
own use or that each SNMP agent process has been configured at startup to use a
unique port. Configuring distinct subnets ensures that each message is routed to the
appropriate target SNMP agent.
