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

switchCfgSpeed

Configures the speed for all ports on a switch.
SYNOPSIS
switchcfgspeed speed
DESCRIPTION
Use this command to configure the port speed on a switch. This command sets the speed for all user
ports. If any port on the switch is not capable of the specified speed setting, an error message is
displayed for that port. The configuration is saved in nonvolatile memory and persists across switch
reboots or power cycles.
On Condor 3-based platforms, the switchCfgSpeed command checks if the requested speed is allowed,
based on the combination configured for the octet that contains the first eight physical ports of the switch
or blade. If the requested speed is not supported by the current octet speed combination, this command
logs a RASlog message and moves on to the next port. Use the portCfgOctetSpeedCombo command
to the set the suggested combination before re-executing the switchCfgSpeed command.
Use the portShow command to display actual port speed settings. Use the portCfgShow command to
display user-configured speed settings.
NOTES
This configuration cannot be set on VE_Ports or VEX_Ports.
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
