By default, the SNMP agent does the following:
•
Receives and sends SNMP messages through NonStop Kernel IPC calls or 
through any available subnet associated with the TCP/IP process $ZTC0 on the 
local node
•
Accepts any request received through TCP/IP that contains the community name 
“public,” and gives the “public” community READONLY access
•
Accepts any request received through the IPC interface and grants the requesting 
manager READWRITE access to all MIB objects supported by the SNMP agent 
and subagents except the SNMP agent’s private zagInProfile group objects 
•
Sends traps through the TCP/IP process $ZTC0 to the Internet address associated 
with each SNMP manager from which a request is received; includes the 
community Tandem in the traps.  $ZTC0 is on the local node. The SNMP manager 
must be using TCP/IP.
•
Sends the event messages that the SNMP agent generates to the EMS collector 
process $0 on the local node.
•
Forwards requests pertaining to managed resources other than those defined in 
the System and SNMP MIB-II groups to the appropriate subagent and returns 
responses back to the requesting manager. The SNMP agent processes the 
SNMP MIB-II groups.
Note. Objects in the SNMP agent’s zagInProfile group (see Using SCF to Configure 
Components of the SNMP Agent Environment on page 2-16) are accessible only if the 
process accessor ID (PAID) of the manager process is compatible with that of the agent 
process.
