10.7.3.9 Switch Engine VLAN Command Register (SWE_VLAN_CMD)
Register #:
180Bh
Size:
32 bits
This register is used to read and write the VLAN or Port VID tables. A write to this address performs the specified access.
For a read access, the Operation Pending bit in the Switch Engine VLAN Command Status Register (SWE_VLAN_C-
MD_STS) indicates when the command is finished. The Switch Engine VLAN Read Data Register (SWE_VLAN_RD_-
DATA) can then be read.
For a write access, the Switch Engine VLAN Write Data Register (SWE_VLAN_WR_DATA) should be written first. The
Operation Pending bit in the Switch Engine VLAN Command Status Register (SWE_VLAN_CMD_STS) indicates when
the command is finished.
