speed {10 | 100 | 1000 | 10000 | auto [10 | 100 | 1000 | 10000]}
no speed
Parameter Description
Default Configuration
Auto-negotiation is enabled by default on copper ports.
Command Mode
Interface Configuration (Ethernet) mode
User Guidelines
To disable auto-negotiation on a port, it is necessary to enter both the speed
and duplex commands without using the auto parameter. Fiber ports do
not support auto-negotiation and therefore require the operator to enter both
the duplex full command and the speed command with the desired
operating bandwidth. Disabling auto-negotiation on 1G copper ports may
lead to random frame loss as the clock master has not been arbitrated by the
auto-negotiation process. Auto-negotiation is required on 10G/40G copper
ports, and is always recommended for copper ports. When the auto parameter
is used with a set of speeds, only those speeds are advertised during auto-
negotiation. Alternatively, if no speed arguments are configured, then all the
speeds which the port is capable of supporting are advertised. Not all ports
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.
40000 Configures the port to 40 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.
