A DSA switch port is a component of a switch that manages one MAC, and can
|
||
|
|
pass Ethernet frames. It can act as a stanadard Ethernet switch port, or have
|
||
|
|
DSA-specific functionality.

possible. Useful when a device supports multiple protocols and

the default is incompatible with the Ethernet device.
