portCfgSpeed
Configures the speed for a single port.
Synopsis portcfgspeed [slotnumber/]portnumber, speed
Description Use this command to set the speed on a specified port. This command disables and then
re-enables the port, and the port comes 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 actual port speed levels. Use the portCfgShow command to
display user-specified speed settings.
Notes This configuration cannot be set on VE/VEX_Ports. For a virtual FC port, the speed is always 10 GbE
and port speed auto-negotiation is not possible.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to “Understanding Virtual Fabric restrictions” on page 32 and “Understanding
Admin Domain restrictions” on page 33 for details.
Operands This command has the following operands:
slotnumber For bladed systems only, specifies the slot number of the port to be
configured, followed by a slash (/).
portnumber Specifies the port to be configured, relative to its slot for bladed systems. Use
switchShow for a listing of valid ports.
speed_level Specifies the speed of a port. This operand is required. Valid values are one
of the following:
0 Auto-sensing mode (hardware). The port automatically configures for
maximum speed.
ax Auto-sensing mode (hardware). The port automatically configures for
maximum speed with enhanced retries.
s Auto-sensing mode (software). The port automatically configures for
maximum speed with enhanced retries.
1 The port is set at a fixed speed of 1 Gbps.
2 The port is set at a fixed speed of 2 Gbps.
4 The port is set at a fixed speed of 4 Gbps.
8 The port is set at a fixed speed of 8 Gbps.
