Ethernet Configuration Commands 399
no speed
Parameter Description
Default Configuration
Auto is enabled by default.
Command Mode
Interface Configuration (Ethernet) mode
User Guidelines
When auto is used with a set of speeds, only those speeds are used by the port
for the negotiation capabilities. Alternatively, if no speed arguments are
configured, then all the speed capabilities are considered. SFP transceivers
support auto-negotiation mode only.
Example
The following example configures the speed operation of Ethernet port 1/0/5
to force 100-Mbps operation.
console(config)#interface gigabitethernet 1/0/5
console(config-if)#speed 100
Parameter Description
10 Configures the port to 10 Mbps operation.
100 Configures the port to 100 Mbps operation.
1000 Configures the port to 1000 Mbps operation.
10000 Configures the port to 10 Gbps operation.
auto The port automatically detects the speed it should run based on
the port at the other end of the link. If you use the 10, 100, or
1000 keywords with the auto keyword, the port only negotiates
at the specified speeds.
