14.3.10Host MAC VLAN2 Tag Register (HMAC_VLAN2)
Offset: | Ah | Size: | 32 bits |
This read/write register contains the VLAN tag field to identify VLAN2 frames. When a VLAN2 frame is detected, the legal frame length is increased from 1518 bytes to 1538 bytes. Refer to Section 9.3, "Virtual Local Area Network (VLAN) Support," on page 114 for additional information.

15:0 | VLAN2 Tag Identifier (VTI2) | R/W | FFFFh |
| This field contains the VLAN Tag used to identify VLAN2 frames. This field |
|
|
| is compared with the 13th and 14th bytes of the incoming frames for VLAN2 |
|
|
| frame detection. |
|
|
| Note: If used, this register is typically set to the standard VLAN value of |
|
|
| 8100h. If both VLAN1 and VLAN2 Tag Identifiers are used, they |
|
|
| should be unique. If both are set to the same value, VLAN1 is |
|
|
| given higher precedence and the maximum legal frame length is |
|
|
| set to 1522. |
