| Setup for CPU Port which is not a member of any VLAN
|
| ========================================================================
|
|
|
| Previous SOHO switch devices were low port count and/or used for Routers. |
| In this environment, the CPU must be a member of all VLANs, so it can |
| route the frames from one VLAN to another. |
| In a high port count managed switch, the CPU is not a router but the |
| manager of the switch. In this environment, the CPU doesn't want to be a |
| member of any VLAN. If it is, it can get saturated with non-management |
| frames preventing it from receiving the important management frames. |
| |
| In order to support the feature, the following has to be provided:
|
|
|
| 1. For the devices that support gsysSetARPDest API: |
| 0) Remove CPU port from VLAN Member Table. |
| 1) Mirror ARPs to the CPU with To_CPU Marvell Tag. |
| 2) Convert unicast frames directed to the CPU into To_CPU Marvell Tag. |
|
|
| 2. For the devices that support gprtSetARPtoCPU API: |
| 0) Remove CPU port from VLAN Member Table. |
| 1) Enable ARP to CPU for each port. |
