Configuring Kernel Stack

Kernel Stack (kstack) uses well known Linux APIs to manage the routes and front panel ports. Open Containers, like the Guest Shell, are Linux environments that are decoupled from the host software. You can install or modify software within that environment without impacting the host software packages.

Verifying a DME Configuration

The following table contains the distinguished name (DN) for each managed object (MO) in the DME payload. Issue a GET request using the DN to verify the configuration was posted or to get information about the configured properties of a particular object.

MO	DN
tcpudpEntity	sys/tcpudp
tcpudpInst	sys/tcpudp/inst

tcpudpInst Properties

The following table contains information about the tcpudpInst properties in the DME payload. For more information about the properties and MOs, see the NX-API DME Model Reference linked in the Related Documentation section below.
