portCfgOctetSpeedCombo portCfgOctetSpeedCombo Sets port speed combination for a port octet. Synopsis portcfgoctetspeedcombo [slot]port combo portcfgoctetspeedcombo [slot]port -default Description Use this command to configure the speed for a port octet. Each port octet contains eight ports. You can configure any three different speed combinations. When you configure a given port, the combination applies to all ports in the octet. You can specify the octet by any port within the octet. To change the first octet, for example, you can specify any port from 0 through 7 as a port argument value. The following speed combinations are supported: • Autonegotiated or fixed port speeds of 32Gbps, 16 Gbps,8 Gbps,4 Gbps, and 2 Gbps (1) • Autonegotiated or fixed port speeds of 10 Gbps,8 Gbps,4 Gbps, and 2 Gbps (2) • Autonegotiated or fixed port speeds of 16 Gbps and 10 Gbps (3) A port octet can be set to any of the three octet combinations, and the ports in the octet can run on any speed supported by its octet combination. This applies to both autonegotiated and fixed speeds. Before you change the octet speed combination, make sure that the following conditions are met: • All fixed speed ports are configured at a speed supported by the new combination. • All online ports in autonegotiation mode have a negotiated speed supported by the new combination. • If a port is running at a speed not supported in the new combo, you must disable the port or change the speed to a supported fixed speed before you can set the combo. If any of the ports does not meet the conditions, the operation fails with an appropriate error message. You can change the port speed or disable the ports and retry the command. The octet combination default is 1. Use the portCfgOctetSpeedCombo port -default command to reset the octet combination to its default value. Notes This command is supported only on 16 Gbps-capable and 32 Gbps-capable platforms. On the Brocade 6505, the command is not supported. The operation of the portCfgOctetSpeedCombo can be disruptive. The execution of this command is subject to Virtual Fabric restrictions that may be in place.
