        Cisco Core Network Switch WS-X6816-10G-2T 16 Port X2 10 Gigabit Ethernet Module



Each port group can operate in either oversubscription mode or performance mode. In oversubscription mode, you can use up to 4 ports in the port group. In performance mode, only the first port of the port group is enabled, and that port comes with enhanced buffering and quality-of-service (QoS) functionality. The other 3 ports in the port group will be administratively shut down. The 16-port 10 Gigabit Ethernet module works in oversubscription mode by default.


The software command Cat6500(config)#[no] hw-module slot x oversubscription port-group y will put port group y (1, 2, 3, or 4) in performance mode and administratively disable the oversubscribed ports (ports 2-4 in port group 1, ports 6-8 in port group 2, ports 10-12 in port group 3, and ports 14-16 in port group 4) and put them in shutdown state. In this mode, the user cannot do “no shut” on the disabled ports.


The following command will display the current configuration of all the port groups in slot x. The output of this command will be something like that shown in Table 1



Table 1. Cat6500# show hw-module slot x Oversubscription


Port Group Oversubscription Mode
1 Enabled
2 Disabled
3 Enabled
4 Disabled
