Example: Handling Oversubscription on 10-ort 10-Gigabit Oversubscribed Ethernet PIC

Table 1 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.

Status of Oversubscription and Throughput

0

1

1

Oversubscription is not active. Each port will receive 10 Gbps throughput.

0

2

2

Oversubscription is not active. Each port will receive 10 Gbps throughput.

0

5

5

Oversubscription is not active. Each port will receive 10 Gbps throughput.

1

0

2

Oversubscription is active. Each port will receive 5 Gbps throughput (with default shaper configuration).

1

4

6

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 configuration).

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

3

6

Oversubscription is active. Each port will receive 5 Gbps throughput (with default shaper configuration).

5

0

10

Oversubscription is active on all ten ports (five port groups). Each port will receive 5 Gbps throughput (with default shaper configuration).
