3.9.3. PCS Bonding Channels Placement Restrictions

There are some placement restrictions for the bonded channels.

Scenario 1

The hard PCS bonding channels span across channels adjacent to PCIe HIP and channels not adjacent to PCIe HIP as shown in the following figure. The master channel of the PCS bonding channels must be assigned to a channel that is adjacent to PCIe HIP.

Figure 186. Hard PCS Bonding Channels Span Across Channels Adjacent to PCIe HIP and Channels Not Adjacent to PCIe HIP

Scenario 2

The hard PCS bonding channels are not allowed to span across two HIPs as shown in the following figure. You must not use the hard PCS bonding. Implement the soft bonding logic in the core if the bonding channels must span across two HIPs.
