VMDS-10492 VSC7440 Datasheet Revision 4.2

PORT_MASK

Port mask.

MASK_MODE=4 (REDIR_PGID):

PORT_MASK[52]: SRC_PORT_MASK_ENA. If set,

SRC_PORT_MASK is AND’ed with destination result.

PORT_MASK[51]: AGGR_PORT_MASK_ENA. If set,

AGGR_PORT_MASK is AND’ed with destination result.

PORT_MASK[50]: VLAN_PORT_MASK_ENA. If set,

VLAN_PORT_MASK is AND’ed with destination result.

PORT_MASK[7:0]: PGID table index.

RT_SEL

Controls routing.

0: No change to routing.

1: Enable routing.

2: Disable routing.

FWD_DIS

If set, forwarding of the frame to front ports is disabled. CPU

extraction is still possible.

xxx

CPU_ENA

Copy frame to specified CPU extraction queue.

xxxx

CPU_Q

CPU extraction queue when frame is forwarded to CPU.

xxxx

MIP_SEL

Controls the MIP selection.

0: No change in MIP selection.

1: Enable MIP.

2: Disable MIP.

If enabled, the MIP_IDX is given by the IPT table.

OAM_Y1731_SEL determines the number of VLAN tags required

for processing a frame in the MIP.

2x x

OAM_Y1731_SEL

Selects which frames are detected as OAM frames by MEP and

MIP.

0: No change in detection.

1: Disable OAM.

2: Detect untagged OAM.

3: Detect single tagged OAM.

4: Detect double tagged OAM.

5: Detect triple tagged OAM.

6: Enable Y1731 OAM unconditionally.

7: Enable any tags and EtherType as OAM unconditionally.

x x

RSVD_LBL_VAL

Use when MPLS_OAM_TYPE = 2, 4, or 5.

Configures the reserved label used as OAM label for this MEP or

MIP. Only the lower 4 bits of the label value is configured.

Normally this field should be set to 13 (GAL label value).

If MPLS_OAM_TYPE is set to 2, 4, or 5 and action record does

not include RSVD_LBL_VAL, then a value of 13 (GAL label

value) is used.

TC_ENA

Use the label’s TC as classified TC.

TTL_ENA

Use the label’s TTL as classified TTL
