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. A Condor 3 ASIC has six octets, each of which
contains eight ports. You can configure up to 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:
•
•
•
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:
•
•
•
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 Condor 3-based platforms and only on the first eight ports of a blade
(slot) or a standalone switch.
The operation of the portCfgOctetSpeedCombo can be disruptive. For example, when you install a 10G
SFP in the first eight ports of the switch and subsequently change the speed for this octet from default to
2 or 3, the SFP does not receive a state change and continues to show the mod_inv state (Incompatible
vendor or module speed mismatch). You must disable and re-enable the ports for the SFP to come online
with the configured speed of 10 Gbps. The same is the case when you replace a 10G SFP with an 8G
SFP or a 16G SFP with a 10G SFP.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
OPERANDS
This command has the following operands:
slot
port
672
Autonegotiated or fixed port speeds of 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)
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.
On bladed systems only, specifies the slot number of the port to be configured,
followed by a slash (/).
Sets the speed combination for the specified port and all other ports in the octet
port group.
