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 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
100BASE-TX: 10half, 10full, 100half, 100full
1000BASE-T: 10half, 10full, 100half, 100full, 1000full
1000BASE-SX/LX/ZX (SFP): 1000full
Command Mode
Interface Configuration (Ethernet - Ports 17-19, Port Channel)
Command Usage
• The 1000BASE-T standard does not support forced mode.
Auto-negotiation should always be used to establish a connection over
any 1000BASE-T port or trunk.
• 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
