Single-Agent Connections

When only one SNMP agent uses a TCP/IP process, defining the request/response

connection is straightforward. Use the default host address value and ensure that at

least one subnet is available to handle communication with the SNMP managers. You

can issue SCF INFO and STATUS commands against the TCP/IP subsystem SUBNET

object to find out about the availability of subnets. For example:

info subnet $ztc0.*

TCPIP Info SUBNET \WEST.$ZTC0.*

Name Devicename *IPADDRESS TYPE *SUBNETMASK

#LOOP0 \NOSYS.$NOIOP 127.0.0.1 LOOP-BACK %HFF000000

#SUBNET1 \WEST.LAN1 130.252.88.1 ETHERNET %HFFFF0000

#SUBNET2 \WEST.LAN2 130.252.87.1 ETHERNET %HFFFF0000

status subnet $ztc0.#subnet2

TCPIP Status SUBNET \WEST.$ZTC0.#SUBNET2

Name Status

#SUBNET2 STARTED

Multiple-Agent Connections

If the same TCP/IP subsystem is handling SNMP agent/manager communication for

more than one SNMP agent process, each SNMP agent must either be reached

through a separate Internet address or must be configured at startup to use a unique

port. You must configure nonoverlapping host address values in request/response

connection definitions.

If a request/response connection has been defined to use the full wild-card

specification (0.0.0.0) to refer to all Internet addresses associated with a particular

TCP/IP process, and you want to start another SNMP agent process to be reached

through the same TCP/IP process, you must configure nonoverlapping host address

values in the two SNMP agents’ request/response connection definitions.
