Handling Oversubscription on a 10-Port 10-Gigabit Ethernet LAN/WAN PIC
Table 1 lists the scenarios of handling oversubscription on the 10-port 10-Gigabit Ethernet LAN/WAN PIC with SFP+ (model number PD-5-10XGE-SFPP) in oversubscribed mode and for different combinations of port groups and active ports on the PIC.
Table 1: Handling Oversubscription on 10–port 10-Gigabit Ethernet LAN/WAN PICs
Number of Port Groups with Two Active Ports (A) | Number of Port Groups with One Active Port (B) | Total Number of Ports Used on PIC (C = Ax2 + B) | 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 | 0 | 6 | Oversubscription is active. Each port will receive 5 Gbps throughput (with default shaper configuration). |
5 | 0 | 10 | Oversubscription is active on all 10 ports (5 port groups). Each port will receive 5 Gbps throughput (with default shaper configuration). |
