This page and its sub-pages define SNMP Agent extensions (AgentX). AgentX is an Agent chain of master agent and subagents. If the master agent does not directly handle a subtree itself, SNMP queries its appropriate subagent. AgentX mode will be probably switched off on hosts where WSO2 SOA Enablement Server SNMP agent is the only SNMP agent running. 'AgentX off' is therefore the default mode.
AgentX consists of a single processing entity called a 'master agent' and zero or more processing entities called 'subagents'. The maser agent and subagents can reside on the same device or communicate via a proxy device. The master agent communicates with the NMS (Network Management Stations), like a traditional SNMP agent. The subagents have direct access to the MIB, whereas the master agent does not. Consequently, the subagents perform management functions on the managed variables, then communicate this information to the master agent via the AgentX protocol, which is not SNMP-based.
AgentX is designed to be independent of any particular SNMP version. An AgentX subagent will work with an SNMPv1, SNMPv2c and/or SNMPv3 master agent without any additional changes.
SNMP Agent Type: Define the type of the AgentX by selecting one from the combo box. Agent types are described further. It is also possible to choose no AgentX.
This page is used to control the SNMP Agent's behavior when it acts as a 'master agent' with a WSO2 SOA Enablement Server subagent included.
Master Agent Port: Set the port number used by the Master Agent.
Authorized SNMP Subagents Table lists the IP addresses of authorized SNMP subagents. If no SNMP manager address is specified, then all IP addresses will be accepted.
IP Addresses can be comma-separated lists of hosts, each of which can be expressed as one of the following:
Numeric IP address, such as 192.168.2.20
Host name, such as server.somewhere.com
CIDR format of subnet notation, such as A.B.C.D/16 192.168.1.0/24 would include all addresses between 192.168.1.0 and 192.168.1.255 192.168.1.0/25 would include all addresses between 192.168.1.0 and 192.168.1.127 192.168.1.128/25 would include 192.168.1.128 and 192.168.1.255
This page is used to control the WSO2 SOA Enablement Server SNMP Agent's behavior when it acts as a 'subagent' connected to an external legacy 'master agent'.
Remote Master Address: When this agent is a subagent, this field specifies the remote master's IP address.
Remote Master Port: When this agent is a subagent, this field specifies the remote master's listening port.
Forward Traps To Master: When this agent is a subagent and the option is checked, SNMP traps will be forwarded to the master agent instead of being sent directly as specified here in trap sinks.
