• 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 for 1 Gbps connections.)
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
• 1000BASE-T and 10GBASE-T do not support forced mode. Auto-negotiation
should always be used to establish a connection over any 1000BASE-T or
10GBASE-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 manually specify the link
attributes with the
speed-duplex
and
flowcontrol
commands.
Example
The following example configures Ethernet port 5 capabilities to 100half and 100full.
Console(config)#interface ethernet 1/5
Console(config-if)#capabilities 100half
Console(config-if)#capabilities 100full
Console(config-if)#
