Speed Auto; Storm-Constrain - H3C S7500E Series Command Reference Manual

speed auto

Syntax
speed auto [ 10 | 100 | 1000 ] *
undo speed
View
Ethernet interface view
Default Level
2: System level
Parameters
10: Sets 10 Mbps as an option for speed auto negotiation.
100: Sets 100 Mbps as an option for speed auto negotiation.
1000: Sets 1000 Mbps as an option for speed auto negotiation.
Description
Use the speed auto command to set options for speed auto negotiation.
Use the undo speed command to restore the default.
By default, an Ethernet port negotiates with its peer for the highest speed supported by both ends. If
the highest speed is not desirable, narrow down the speed option list for negotiation with the speed
auto command. The two ends will pick out the highest speed supported by both ends on the list.
The speed command and the speed auto command supersede each other, and whichever is
configured last takes effect.
For example, 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.
This function is available for auto-negotiation-capable 100 MB or Gigabit Layer-2 Ethernet
electrical ports only.
To avoid negotiation failure, ensure that at least one speed option is supported at both ends.
Examples
# Configure port GigabitEthernet 2/0/1 to use 10 Mbps and 1000 Mbps for speed negotiation.
