4.3.2. Ethernet Header Insertion/Removal
The Ethernet header insertion block inserts Ethernet header to incoming eCPRI packet on TX path. Optionally it can insert IPv4/UDP headers to the packet based on the configuration. The Ethernet header removal block removes Ethernet header to incoming eCPRI packet on RX path. Optionally it can remove IPv4/UDP headers to the packet based on the configuration selected. The Ethernet header encapsulated the incoming eCPRI packets as shown in the figure below. The table listed the source of each fields within the Ethernet header.
If you select IPv4 header as encapsulation to eCPRI payload, the following table lists the CSR to fill the IPv4 header fields:
Figure 7. Ethernet Header Field
Ethernet Header Field | CSR |
---|---|
Destination MAC address | Destination MAC address <N=0,1,2,3,4,5,6,7> Register 0,1 With enabled Advance mapping mode: N – eCPRI message PCID [2:0] Default mapping mode: N = 0 for all eCPRI message |
Source MAC address | Source MAC address register 0, and 1 |
VLAN tag | VLAN Tag Register <N=0,1,2,3,4,5,6,7> With Enabled advance mapping mode: N – eCPRI message PCID [2:0] Default mapping mode: N = 0 for all eCPRI message |
