Speed Auto - HP 3100 v2 Series Command Reference Manual

Description
Use speed to set the speed of an Ethernet interface.
Use undo speed to restore the default.
By default, an Ethernet interface automatically negotiates a speed with the peer.
For an Ethernet copper port, use the speed command to set its speed to match the speed of the peer
interface.
For a fiber port, use the speed command to set its speed to match the rate of a pluggable
transceiver.
NOTE:
The keywords 10 and 1000 are unavailable on SFP ports inserted with 100-Mbps SFP transceiver
modules. The keywords 10 and 100 are unavailable on SFP ports inserted with 1000-Mbps SFP
transceiver modules.

Description
Use speed auto to set options for speed auto negotiation.
Use undo speed to restore the default.
By default, an Ethernet interface automatically negotiates a speed with the peer.
The speed command and the speed auto command supersede each other. The command that is
configured last takes effect.
If you configure speed 100 after configuring speed auto 100 1000 on an interface, the interface
speed is set to 100 Mbps by force without negotiation. If you configure speed auto 100 1000 after
configuring speed 100 on the interface, the interface negotiates with its peer, and the negotiated
speed is either 100 Mbps or 1000 Mbps.
