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.
