- 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.
