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
• 100BASE-TX: 10half, 10full, 100half, 100full
• 1000BASE-T: 10half, 10full, 100half, 100full, 1000full
• SFP: 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 capabilites command. When auto-negotiation is disabled, you must manually specify the link attributes with
the speed-duplex and flowcontrol commands.
Example
The following
Example configures Ethernet port 5 capabilities to 100half, 100full and flow control.
