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 {10000full | 1000full | 100full | 100half | 10full |
10half | flowcontrol | symmetric}
• 10000full - Supports 10 Gbps full-duplex operation
• 1000full - Supports 1 Gbps 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 (SFP): 1000full
• 10GBASE-SR/LR/ER (XFP): 10000full
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
capabilites command. When auto-negotiation is disabled, you must
manually specify the link attributes with the speed-duplex and
flowcontrol commands.
