Setting Auto-Negotiation Options
The negotiation auto command provides a mode option for configuring an individual port to forced master/
forced slave once auto-negotiation is enabled.

Command Reference.
Adjust the keepalive timer
Use the keepalive command to change the time interval between keepalive messages on the interfaces. The
interface sends keepalive messages to itself to test network connectivity on the interface.
To change the default time interval between keepalive messages, use the following command:
Caution: Ensure that only one end of the node is configured as forced-master and the other is configured as
forced-slave. If both are configured the same (that is both as forced-master or both as forced-slave), the show
interface
command will flap between an auto-neg-error and forced-master/slave states.
