then brought back online immediately.

Table 80 on page 812 lists the scenarios of handling oversubscription on the 10-port
10-Gigabit Oversubscribed Ethernet (OSE) PIC for different combinations of port
groups and active ports on the PIC.

Line Rate Mode: In this mode, only five alternate ports (ports 0, 2, 4, 6, and 8)
are enabled. The PIC operates in line rate mode at 50 Gbps.

Status of Oversubscription and Throughput
Oversubscription is not active. Each port will receive
10 Gbps throughput.
Oversubscription is not active. Each port will receive
10 Gbps throughput.
Oversubscription is not active. Each port will receive
10 Gbps throughput.
Oversubscription is active. Each port will receive 5

Oversubscription is active for the port group that has
two active ports. Each port in this port group will
receive 5 Gbps throughput (with default shaper

For the remaining four ports, oversubscription is not
active. Each port will receive 10 Gbps throughput.
