capabilities
Use this command to advertise 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
• 100BASE-TX: 10half, 10full, 100half, 100full
• 1000BASE-T: 10half, 10full, 100half, 100full, 1000full
• 1000BASE-SX/LX/LH: 1000full
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
When auto-negotiation is enabled with the negotiation command, 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.
