(10/100/1000) or to auto or the link may not come up.
C-Series, E-Series, S-Series, Z-Series, S4810
Syntax
speed {10 | 100 | 1000 | auto}
To return to the default setting, use the no speed {10 | 100 | 1000} command.
Parameters
10 Enter the keyword 10 to set the interface’s speed to 10 Mb/s.
NOTE: This interface speed is not supported on the LC-EH-GE-50P
or the LC-EJ-GE-50P card. If the command is entered for these
interfaces, an error message appears.
100 Enter the keyword 100 to set the interface’s speed to 10/100 Mb/s.
NOTE: When this setting is enabled, only 100Base-FX optics are
supported on the LC-EH-GE-50P or the LC-EJ-GE-50P card.
1000 Enter the keyword 1000 to set the interface’s speed to 1000 Mb/s.
Auto-negotiation is enabled. For more information, refer to
negotiation auto.
NOTE: When this setting is enabled, only 100oBase-FX optics are
supported on the LC-EH-GE-50P or the LC-EJ-GE-50P card.
auto Enter the keyword auto to set the interface to auto-negotiate its
