Portcfgspeed - Brocade Communications Systems Brocade 8/12c Command Reference Manual

portCfgSpeed

Configures the speed for a port or a range of ports.
SYNOPSIS
portcfgspeed [slot/]port speed
portcfgspeed -i [index1[-index2] [-f] speed]
portcfgspeed -slot [slot1[-slot2] [...] speed
portcfgspeed -h
DESCRIPTION
Use this command to set the speed on a specified port or port range. This command disables and then
re-enables the ports, and the ports come online with the new speed setting. The configuration is saved in
nonvolatile memory and is persistent across switch reboots or power cycles. Use the portShow
command to display supported port speed levels. Use the portCfgShow command to display configured
speed settings.
On Condor 3-based plat forms ,the portCfgSpeed command checks if the requested speed is allowed,
based on the combination configured for the octet that contains the port. If the speed is not supported by
the current octet speed combination, this command exits with a warning message that displays the
combination compatible with desired speed . Use the portCfgOctetSpeedCombo command to the set
the suggested combination before re-executing the portCfgSpeed command.
You can identify a single port to be configured by its port number or by its port index number. Port ranges
are supported with index numbers or by specifying a slot or a slot range. Use switchShow for a listing of
valid ports, slots, and port index numbers.
Specifying multiple ports with the index (-i) or slot (-s) option is supported only if PortSwap is disabled.
They are not supported on GbE ports and configured F_Port trunks. Use the -i option without a port index
argument to display the portSwap status, or alternately use portSwapShow.
NOTES
This configuration cannot be set on VE/VEX_Ports. For a virtual FC port, the speed is always 10 GbE
and port speed autonegotiation is not possible.
Speed configuration is not applicable to FCoE ports.
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.

For bladed systems only, specifies the slot number of the ports to be configured,
followed by a slash (/).
Configures a single port identified by the port number relative to the slot on bladed
systems.
Configures a port or a range of ports identified by port index numbers. Multiple
port ranges are not supported with this command.
