This article provides methods for configuring the network coredump feature in vSphere ESXi 5.x. For more information on the network coredump functionality, see ESXi Network Dump Collector in VMware vSphere 5.x/6.0 (1032051). For more information on configuring a network dump collector to receive diagnostic information, see Configuring the Network Dump Collector service in vSphere 5.0 (2002954).
The vSphere ESXi 5.x network coredump client can be configuring using esxcli
or using Host Profiles. Select a method appropriate to your environment. A host configured using esxcli
can be subsequently used as a reference for creating host profiles.
Generally, the host is configured with a VMkernel interface attached to a standard vSwitch which has an active uplink port, and the target netdump server's IP address and port is specified.
