LOG_MSG_INT

Controls logMessageInterval when REW_CMD[5] = 1:

For multicast Delay_Resp frames, SWAP_MAC_ENA and LOG_MSG_INT encode a new

logMessageInterval:

SWAP_MAC_ENA=0, LOG_MSG_INT=0: logMessageInterval = 0

SWAP_MAC_ENA=0, LOG_MSG_INT=1: logMessageInterval = 1

...

SWAP_MAC_ENA=0, LOG_MSG_INT=7: logMessageInterval = 7

SWAP_MAC_ENA=1, LOG_MSG_INT=0: logMessageInterval = –8

SWAP_MAC_ENA=1, LOG_MSG_INT=1: logMessageInterval = –7

...

SWAP_MAC_ENA=1, LOG_MSG_INT=7: logMessageInterval = –1

MASK_MODE

Controls how PORT_MASK is applied.

0: OR_DSTMASK: Or PORT_MASK with destination mask.

1: AND_VLANMASK: And PORT_MASK with VLAN mask.

2: REPLACE_PGID: Replace PGID port mask from MAC table lookup by PORT_MASK.

3: REPLACE_ALL: Use PORT_MASK as final destination set replacing all other port

masks. Note that with REPLACE_ALL, the port mask becomes sticky and cannot be

modified by later processing steps.

4: REDIR_PGID: Redirect using PORT_MASK[7:0] as PGID table index. See

PORT_MASK for extra configuration options.

options. Note that the port mask becomes sticky and cannot be modified by subsequent

processing steps.

5: OR_PGID_MASK: Or PORT_MASK with PGID port mask from MAC table lookup.

6: Reserved.

7: Reserved.

The CPU port is untouched by MASK_MODE.

PORT_MASK

Port mask applied to the forwarding decision.

MASK_MODE=4:

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.

MASK_MODE=4:

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.

MIRROR_PROBE

Mirroring performed according to configuration of a mirror probe.

0: No mirroring.

1: Mirror probe 0.

2: Mirror probe 1.

3: Mirror probe 2.
