Basic IP Parameters and Defaults – HP 6208M-SX

IP is enabled by default. The following tables list the switch IP parameters, their default values, and where to find configuration information.

NOTE: The HP 6208M-SX also provides IP multicast forwarding, which is enabled by default. For information about this feature, see the “Configuring Basic Features” chapter of the Installation and Getting Started Guide.
