Release 5.5 for VMware ESXi supports SNMPv1, SNMPv2c, and SNMPv3 with a stand-alone snmpd process. This release features support for monitoring multiple IP Stacks. The standard IP-MIB, UDP-MIB, and TCP-MIB may be used with a context set to the IP Stack Name as found in ENTITY-MIB entLogicalTable or via command: esxcli network ip netstack list An example using net-snmp's snmpwalk command:: snmpwalk -v2c -n defaultTcpipStack ip No vDR instrumentation is yet available. This agent supports read-only protocol operations. This implies that configuring the SNMPv3 Agent can not be done via SET operations. Hence IETF standard SNMPv3 agent configuration mibs are not provided. The SNMPv3 protocol is fully supported once configured via the CLI command interface (esxcli system snmp) command set or vCenter Server host profiles. Lastly this SNMP agent provides one read-only view of the entire system to which all SNMPv3 users configured are assigned.
