Accton Technology VDSL Switch-VS4512, Management Manual, Page: 233 / 334

Interface Commands
4-87
Command Usage
• When auto-negotiation is enabled the switch will negotiate the best settings for
a link based on the capabilities command. When auto-negotiation is disabled,
you must manually specify the link attributes with the speed-duplex and
flowcontrol commands.
• If autonegotiation is disabled, auto-MDI/MDI-X pin signal configuration will also
be disabled for the RJ-45 ports.
Example
The following example configures port 11 to use autonegotiation.

capabilities
This command advertises the port capabilities of a given interface during
autonegotiation. Use the
no form with parameters to remove an advertised
capability, or the no form without parameters to restore the default values.
Syntax
[ no ] capabilities { 1000full | 100full | 100half | 10full | 10half | flowcontrol |
symmetric }
• 1000full - Supports 1000 Mbps full-duplex operation
• 100full - Supports 100 Mbps full-duplex operation
• 100half - Supports 100 Mbps half-duplex operation
• 10full - Supports 10 Mbps full-duplex operation
• 10half - Supports 10 Mbps half-duplex operation
• flowcontrol - Supports flow control
• symmetric (Gigabit only) - When specified, the port transmits and receives
pause frames; when not specified, the port will auto-negotiate to determine
the sender and receiver for asymmetric pause frames. (
The current switch
ASIC only supports symmetric pause frames. )
Default Setting
• 1000BASE-T: 10half, 10full, 100half, 100full, 1000full
• 1000BASE-SX/LX/LH: 1000full
