• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

Bits 4-5: WAN Extract Decap Source (WEDS[2:1])
Note that not all decapsulators are available in all Forwarding Modes. The user should consult the forwarding
diagrams in Section 8.9.1 for the available decapsulators for the configured Forwarding Mode.
Bit 3: WAN Extract VLAN ID Trap (WEVIT)
Note: Invalid if the WAN Extract Decapsulator (selected by WEDS) has been configured to add an Ethernet Header
(in PP.DMCR.DAE[1:0]). Adding an Ethernet header implies that there is no VLAN ID to Trap.
Bit 2: WAN Extract Ethernet Type Trap (WEETT)
Note: Invalid if the WAN Extract Decapsulator (selected by WEDS) has been configured to add an Ethernet Header
(in PP.DMCR.DAE[1:0]). Adding an Ethernet header implies that there is no Ethernet Type field to Trap. Note that
WAN Extract Ethernet Type trapping is not available for frame formats in which the Ethernet Type field is more than
32 bytes into the frame. Thus, Ethernet Type trapping is not applicable on WAN frames in the LLC/SNAP frame
format with 4/8 byte frame headers plus dual VLAN Tags.
Bit 1: WAN Extract Destination Address Trap (WEDAT)
Note: Invalid if the WAN Extract Decapsulator (selected by WEDS) has been configured to add an Ethernet Header
(in PP.DMCR.DAE[1:0]). Adding an Ethernet header implies that there is no Ethernet DA to Trap.
Bit 0: WAN Extract Header Trap (WEHT)
