In certain situations, it is useful to be able to auto-negotiate a specific speed and

duplex value. In these situations, the switch can allow for attachment at an

operating mode other than its highest supported value.

For example, if the switch only advertises a 100 Mbps full-duplex capability on a

specific link, then the link only goes active if the neighboring device is also

capable of auto-negotiating a 100 Mbps full-duplex capability. This prevents

mismatched speed/duplex modes if customers disable auto-negotiation on the

neighboring device.

CANA is available through the Command Line Interface (CLI). The CLI provides

the following commands for CANA:

• show auto-negotiation-advertisements [port

<portlist>]

• no auto-negotiation-advertisements [port <portlist>]

To show hardware advertisement capabilities (userExec mode):

• show auto-negotiation-capabilities [port <portlist>]

To configure advertisements (interface configuration mode):

• auto-negotiation-advertisements [port <portlist>]

[10-full] [10-half] [100-full] [100-half]

[1000-full] [1000-half] [asymm-pause-frame] [none]

[pause-frame]

• default auto-negotiation-advertisements [port

<portlist>]

When custom autonegotiation advertisements is in use on a port, autonegotiation

is displayed as “custom” in the console and web-based management interfaces.

Note: This feature is available only for built-in 10/100 ethernet ports.
