(with text nodes and any number of top-level elements). The XML data type is not required to be bound to an XML schema when the data is checked for a well-formed format, but malformed data is rejected.
Untyped XML can be used when the schema is not known to be apriori and therefore results in a map-based solution that is not possible to implement. If schemas are known, but mapping to relational data models is complex and difficult to maintain, or there are multiple schemas that are l

Set the default gateway, that is, set the default route. You can use the route command provided by linux to add or delete route information.

If the DHCP protocol on vnic 8 is enabled,Set vnic 8 to automatically obtain the ip address,You can ping the internet.
Try Setting gw of vnic 8 to 10.1.10.1,When the ip address is set to 10.1.10.2, You can ping the internet.
